1. THE POLE-CLIMBING SLOTH

A slippery sloth climbs six feet up a utility pole during the day, then slides back down five feet during the night. If the pole is 30 feet high and the sloth starts from the ground (zero feet), how many days does it take the sloth to reach the top of the pole?

Answer: 25 days. The math here boils down to a net gain of one foot per day, along with a threshold (24 feet at the beginning of a day) that must be attained so that the sloth can get to the 30-foot mark within a given day. After 24 days and 24 nights, the sloth is 24 feet up. On that 25th day, the sloth scrambles up six feet, attaining the 30-foot top of the pole. Left to the reader is a motivation for the sloth to attempt this feat in the first place. Perhaps there is something tasty atop the pole?

2. THE PIRATE RIDDLE

A group of five pirates have to divide up their bounty of 100 coins, as described in the video below. The captain gets to propose a distribution plan, and all five of the pirates vote "yarr" or "nay" on the proposal. If a majority votes "nay," the captain walks the plank. The pirates are arranged in order, and vote in that order: the captain, Bart, Charlotte, Daniel, and Eliza. If a majority vote "nay" and the captain walks the plank, the captain's hat goes to Bart, and the process repeats down the line, with a series of proposals, votes, and other acceptance or plank-walking.

How can the captain stay alive, while getting as much gold as possible? (In other words, what is the optimal amount of gold the captain should offer to each pirate, himself included, in his proposal?) Watch the video below for all the rules.

Answer: The captain should propose that he keep 98 coins, distribute one coin each to Charlotte and Eliza, and offer nothing to Bart and Daniel. Bart and Daniel will vote nay, but Charlotte and Eliza have done the math and vote yarr, knowing that the alternative would get them even less booty.

3. THE HIKER'S DILEMMA

A hiker comes across an intersection where three roads cross. He looks for the sign indicating the direction to his destination city. He finds that the pole carrying three city names and arrows pointing to them has fallen. He picks it up, considers it, and pops it back into place, pointing out the correct direction for his destination. How did he do it?

Answer: He knew which city he had just come from. He pointed that arrow back toward his origin point, which oriented the signs properly for his destination and a third city.

4. THE PASSCODE RIDDLE

In the video below, the rules of this riddle are laid out. Here's a snippet: Three team members are imprisoned, and one is allowed the opportunity to escape by facing a challenge. Given perfect logical skills, how can the remaining two team members listen in on what the chosen team member does, and infer the three-digit passcode to get them out?

Answer: The passcode is 2-2-9, for hallway 13.

5. COUNTING BILLS

I had a wad of money in my pocket. I gave half away and of what remained, I spent half. Then, I lost five dollars. That left me with just five bucks. How much money did I start with?

Answer: 40 dollars.

6. THE AIRPLANE FUEL RIDDLE

Professor Fukanō plans to circumnavigate the world in his new airplane, as shown in the video below. But the plane's fuel tank doesn't hold enough for the trip—in fact, it holds only enough for half the trip. Fukanō has two identical support planes, piloted by his assistants Fugori and Orokana. The planes can transfer fuel in midair, and they must all take off from and land at the same airport on the equator.

How can the three cooperate and share fuel so that Fukanō gets all the way around the world and nobody crashes? (Check the video for more details.)

Answer: All three planes took off at noon, flying west, fully loaded with fuel (180 kiloliters each). At 12:45, each plane has 135 kl remaining. Orokana gives 45 kl to each of the other two planes, then heads back to the airport. At 14:15, Fugori gives another 45 kl to the professor, then heads back to the airport. At 15:00, Orokana flies east, effectively flying toward the professor around the globe. At precisely 16:30, Orokana gives him 45 kl and flips around, now flying alongside the professor. Meanwhile, Fugori takes off and heads for the pair. He meets them at 17:15 and transfers 45 kl to each plane. All three planes now have 45 kl and make it back to the airport.

7. THE HAYSTACK PROBLEM

A farmer has a field with six haystacks in one corner, a third as many in another corner, twice as many in a third corner, and five in the fourth corner. While piling the hay together in the center of the field, the farmer let one of the stacks get scattered all over the field by the wind. How many haystacks did the farmer end up with?

Answer: Just one. The farmer had piled them all up the middle, remember?

8. THE THREE ALIENS RIDDLE

In this video riddle, you have crashed landed on a planet with three alien overlords named Tee, Eff, and Arr. There are also three artifacts on the planet, each matching a single alien. To appease the aliens, you need to match up the artifacts with the aliens—but you don't know which alien is which.

You are allowed to ask three yes-or-no questions, each addressed to any one alien. You can choose to ask the same alien multiple questions, but you don't have to.

It gets more complex, though, and this wickedly tricky riddle is best explained (both its problem and its solution) by watching the video above.

9. THE FARMER'S WILL

One day, a farmer decided to do some estate planning. He sought to apportion his farmland among his three daughters. He had twin daughters, as well as a younger daughter. His land formed a 9-acre square. He wanted the eldest daughters to get equally sized pieces of land, and the younger daughter to get a smaller piece. How can he divide up the land to accomplish this goal?

Three square illustrations.
Three possible solutions.
Chris Higgins

Answer: Shown above are three possible solutions. In each, the box marked 1 is a perfect square for one twin, and the two sections marked 2 combine to make a square of the same size for the second twin. The area marked 3 is a small perfect square for the youngest child.

10. COINS

In my hand I have two American coins that are currently minted. Together, they total 55 cents. One isn't a nickel. What are the coins?

Answer: A nickel and a 50-cent piece. (Lately the U.S. 50-cent piece features John F. Kennedy.)

(Adapted from a brain teaser by Jan Weaver.)

11. THE BRIDGE RIDDLE

A student, a lab assistant, a janitor, and an old man need to cross a bridge to avoid being eaten by zombies, as shown in the video below. The student can cross the bridge in one minute, the lab assistant takes two minutes, the janitor takes five minutes, and the professor takes 10 minutes. The group only has one lantern, which needs to be carried on any trip across. The zombies arrive in 17 minutes, and the bridge can only hold two people at a time. How can you get across in the time allotted, so you can cut the rope bridge and prevent the zombies from stepping on the bridge and/or eating your brains? (See the video for more details!)

Answer: The student and lab assistant go together first, and the student returns, putting three minutes total on the clock. Then, the professor and the janitor take the lantern and cross together, taking 10 minutes, putting the total clock at 13 minutes. The lab assistant grabs the lantern, crosses in two minutes, then the student and lab assistant cross together just in the nick of time—a total of 17 minutes.

12. LITTLE NANCY ETTICOAT

Here's a nursery rhyme riddle:

Little Nancy Etticoat
In her white petticoat
With a red nose—
The longer she stands
The shorter she grows

Given this rhyme, what is "she?"

Answer: A candle.

(Adapted from a brain teaser by J. Michael Shannon.)

13. THE GREEN-EYED LOGIC PUZZLE

In the green-eyed logic puzzle, there is an island of 100 perfectly logical prisoners who have green eyes—but they don't know that. They have been trapped on the island since birth, have never seen a mirror, and have never discussed their eye color.

On the island, green-eyed people are allowed to leave, but only if they go alone, at night, to a guard booth, where the guard will examine eye color and either let the person go (green eyes) or throw them in the volcano (non-green eyes). The people don't know their own eye color; they can never discuss or learn their own eye color; they can only leave at night; and they are given only a single hint when someone from the outside visits the island. That's a tough life!

One day, a visitor comes to the island. The visitor tells the prisoners: "At least one of you has green eyes." On the 100th morning after, all the prisoners are gone, all having asked to leave on the night before. How did they figure it out?

Watch the video for a visual explanation of the puzzle and its solution.

Answer: Each person can't be sure whether they have green eyes. They can only deduce this fact by observing the behavior of the other members of the group. If each person looks at the group and sees 99 others with green eyes, then logically speaking, they must wait 100 nights to give the others opportunities to stay or leave (and for each to make that calculation independently). By the 100th night, using inductive reasoning, the entire group has offered every person in the group an opportunity to leave, and can figure that it's safe to go.

14. THE NUMBER ROW

The numbers one through 10, below, are listed in an order. What is the rule that causes them to be in this order?

8 5 4 9 1 7 6 10 3 2

Answer: The numbers are ordered alphabetically, based on their English spelling: eight, five, four, nine, one, seven, six, ten, three, two.

(Adapted from a brain teaser by Carl Proujan.)

15. THE COUNTERFEIT COIN PUZZLE

In the video below, you must find a single counterfeit coin among a dozen candidates. You're allowed the use of a marker (to make notes on the coins, which doesn't change their weight), and just three uses of a balance scale. How can you find the one counterfeit—which is slightly lighter or heavier than the legitimate coins—among the set?

Answer: First, divide the coins into three equal piles of four. Put one pile on each side of the balance scale. If the sides balance (let's call this Case 1), all eight of those coins are real and the fake must be in the other pile of four. Mark the legitimate coins with a zero (circle) using your marker, take three of them, and weigh against three of the remaining unmarked coins. If they balance, the remaining unmarked coin is counterfeit. If they don't, make a different mark (the video above suggests a plus sign for heavier, minus for lighter) on the three new coins on the scale. Test two of these coins on the scale (one on each side)—if they have plus marks, the heavier of those tested will be the fake. If they have minus marks, the lighter is the fake. (If they balance, the coin not tested is the fake.) For Case 2, check out the video.

16. THE ESCALATOR RUNNER

Each step of an escalator is 8 inches taller than the previous step. The total vertical height of the escalator is 20 feet. The escalator moves upward one half step per second. If I step on the lowest step at the moment it is level with the lower floor, and run up at a rate of one step per second, how many steps do I take to reach the upper floor? (Note: Do not include the steps taken to step on and off the escalator.)

Answer: 20 steps. To understand the math, take a period of two seconds. Within that two seconds, I run up two steps on my own power, and the escalator lifts me the height of an extra step, for a total of three steps—this could also be expressed as 3 times 8 inches, or two feet. Therefore, over 20 seconds I reach the upper floor having taken 20 steps.

(Adapted from a brain teaser by Carl Proujan.)

17. A RIVER CROSSING PUZZLE

In the video riddle below, three lions and three wildebeest are stranded on the east bank of a river and need to reach the west. A raft is available, which can carry a maximum of two animals at a time and needs at least one animal onboard to row it across. If the lions ever outnumber the wildebeest on either side of the river (including the animals in the boat if it's on that side), the lions will eat the wildebeest.

Given these rules, how can all the animals make the crossing and survive?

Answer: There are two optimal solutions. Let's take one solution first. In the first crossing, one of each animal goes from east to west. In the second crossing, one wildebeest returns from west to east. Then on the third crossing, two lions cross from east to west. One lion returns (west to east). On crossing five, two wildebeest cross from east to west. On crossing six, one lion and one wildebeest return from west to east. On crossing seven, two wildebeest go from east to west. Now all three wildebeest are on the west bank, and the sole lion on the west bank rafts back to the east. From there (crossings eight through eleven), lions simply ferry back and forth, until all the animals make it.

For the other solution, consult the video.

18. THE THREE WATCHES

I am marooned on an island with three watches, all of which were set to the correct time before I got stuck here. One watch is broken and doesn't run at all. One runs slow, losing one minute every day. The final watch runs fast, gaining one minute every day.

After being marooned for a moment, I begin to worry about timekeeping. Which watch is most likely to show the correct time if I glance at the watches at any particular moment? Which would be least likely to show the correct time?

Answer: We know that the stopped watch must tell the correct time twice a day—every 12 hours. The watch that loses one minute per day will not show the correct time until 720 days into its cycle of time loss (60 minutes in an hour times 12 hours), when it will momentarily be exactly 12 hours behind schedule. Similarly, the watch that gains one minute a day is also wrong until 720 days after its journey into incorrectness, when it will be 12 hours ahead of schedule. Because of this, the watch that doesn't run at all is most likely to show the correct time. The other two are equally likely to be incorrect.

(Adapted from a brain teaser by Carl Proujan.)

19. EINSTEIN'S RIDDLE

In this riddle, erroneously attributed to Albert Einstein, you're presented with a series of facts and must deduce one fact that's not presented. In the case of the video below, a fish has been kidnapped. There are five identical-looking houses in a row (numbered one through five), and one of them contains the fish.

Watch the video for the various bits of information about the occupants of each house, the rules for deducing new information, and figure out where that fish is hiding! (Note: You really need to watch the video to understand this one, and the list of clues is helpful too.)

Answer: The fish is in House 4, where the German lives.

20. MONKEY MATH

Three castaways and a monkey are marooned together on a tropical island. They spend a day collecting a large pile of bananas, numbering between 50 and 100. The castaways agree that the next morning the three of them will divide up the bananas equally among them.

During the night, one of the castaways wakes up. He fears that the others might cheat him, so he takes his one-third share and hides it. Since there is one banana more than a quantity which could be divided equally into thirds, he gives the extra banana to the monkey and goes back to sleep.

Later in the night, a second castaway awakes and repeats the same behavior, plagued by the same fear. Again, he takes one-third of the bananas in the pile and again the quantity is one greater than would allow an even split into thirds, so he hands the extra banana to the monkey and hides his share.

Still later, the final castaway gets up and repeats the exact same procedure, unaware that the other two have already done it. Yet again, he takes a third of the bananas and ends up with one extra, which he gives to the monkey. The monkey is most pleased.

When the castaways meet in the morning to divide the banana loot, they all see that the pile has shrunk considerably, but say nothing—they're each afraid of admitting their nighttime banana thievery. They divide the remaining bananas three ways, and end up with one extra for the monkey.

Given all this, how many bananas were there in the original pile? (Note: There are no fractional bananas in this problem. We are always dealing with whole bananas.)

Answer: 79. Note that if the pile were bigger, the next possible number that would meet the criteria above would be 160—but that's outside the scope listed in the second sentence ("between 50 and 100") of the puzzle.

(Adapted from a brain teaser by Carl Proujan.)

21. THE VIRUS RIDDLE

In the video below, a virus has gotten loose in a lab. The lab is a single story building, built as a 4x4 grid of rooms, for a total of 16 rooms—15 of which are contaminated. (The entrance room is still safe.) There's an entrance at the northwest corner and an exit at the southeast corner. Only the entrance and exit rooms are connected to the outside. Each room is connected to its adjacent rooms by airlocks. Once you enter a contaminated room, you must pull a self-destruct switch, which destroys the room and the virus within it—as soon as you leave for the next room. You cannot re-enter a room after its switch has been activated.

If you enter via the entrance room and exit via the exit room, how can you be sure to decontaminate the entire lab? What route can you take? See the video for a great visual explanation of the problem and the solution.

Answer: The key lies in the entrance room, which is not contaminated and which you may therefore re-enter after exiting it. If you enter that room, move one room to the east (or the south) and decontaminate it, then re-enter the entrance room and destroy it on your way to the next room. From there, your path becomes clear—you actually have four options to complete the path, which are shown in the video above. (Sketching this one on paper is an easy way to see the routes.)

22. THE IN-LAW CONUNDRUM

According to puzzle book author Carl Proujan, this one was a favorite of author Lewis Carroll.

The prime minister is planning a dinner party, but he wants it to be small. He doesn't like crowds. He plans to invite his father's brother-in-law, his brother's father-in-law, his father-in-law's brother, and his brother-in-law's father.

If the relationships in the prime minister's family happened to be arranged in the most optimal manner, what would be the minimum possible number of guests be at the party? Note that we should assume that cousin marriages are permitted.

Answer: One. It is possible, through some complex paths in the prime minister's family, to get the guest list down to one person. Here's what must be true: The PM's mother has two brothers. Let's call them brother 1 and brother 2. The PM also has a brother who married the daughter of brother 1, a cousin. The PM also has a sister who married the son of brother 1. The host himself is married to the daughter of brother 2. Because of all this, brother 1 is the PM's father's brother-in-law, the PM's brother's father-in-law, the PM's father-in-law's brother, and the PM's brother-in-law's father. Brother 1 is the sole guest at the party.

(Adapted from a brain teaser by Carl Proujan.)

23. THE PRISONER BOXES RIDDLE

In the video, ten band members have had their musical instruments randomly placed in boxes marked with pictures of musical instruments. Those pictures may or may not match up with the contents.

Each member gets five shots at opening boxes, trying to find their own instrument. Then, they must close the boxes. They're not allowed to communicate about what they find. If the entire band fails to find their instruments, they'll all be fired. The odds of them randomly guessing their way through this is one in 1024. But the drummer has an idea that will radically increase their odds of success, to more than 35 percent. What's his idea?

Answer: The drummer told everyone to first open the box with the picture of their instrument. If their instrument is inside, they're done. If not, the band member observes what instrument is found, then opens the box with that instrument's picture on it—and so forth. Watch the video for more on why this works mathematically.

24. S-N-O-W-I-N-G

One snowy morning, Jane awoke to find that her bedroom window was misty with condensation. She drew the word "SNOWING" on it with her finger. Then she crossed out the letter N, turning it into another English word: "SOWING." She continued this way, removing one letter at a time, until there was just one letter remaining, which is itself a word. What words did Jane make, and in what order?

Answer: Snowing, sowing, owing, wing, win, in, I.

(Adapted from a brain teaser by Martin Gardner.)

25. THE MYSTERY STAMPS

While on vacation on the island of Bima, I visited the post office to send some packages home. The currency on Bima is called the pim, and the postmaster told me that he only had stamps of five different values, though these values are not printed on the stamps. Instead, the stamps have colors.

The stamps were black, red, green, violet, and yellow, in descending order of value. (Thus the black stamps had the highest denomination and yellow the lowest.)

One package required 100 pims worth of stamps, and the postmaster handed me nine stamps: five black stamps, one green stamp, and three violet stamps.

The other two packages required 50 pims worth each; for those, the postmaster handed me two different sets of nine stamps. One set comprised one black stamp and two each of the other colors. The other set was five green stamps, and one each of the other colors.

What would be the smallest number of stamps needed to mail a 50-pim package, and what colors would they be?

Answer: Two black stamps, one red stamp, one green stamp, and one yellow stamp. (It may help to write out the stamp formulas given above using the various b, r, g, v, and y. Because we know that b > r > g > v > y, and we have three described cases, we can do some algebra to arrive at values for each stamp. Black stamps are worth 18 pim, red are worth 9, green are worth 4, violet are worth 2, and yellow are worth 1.)

How 25 of Your Favorite Halloween Candies Got Their Names

iStock/mediaphotos
iStock/mediaphotos

Soon, small superheroes and ghosts and all sorts of other strange creatures will be canvassing your neighborhood begging for candy. But as you pass out your wares, you can also dole out some (not terribly spooky) etymologies.

1. 3 MUSKETEERS

3 Musketeers candy bar.
Erin McCarthy

When 3 Musketeers bars were introduced in 1932, they consisted of three flavors—chocolate, vanilla, and strawberry—and were labeled "The 3 Musketeers, Chocolate, Vanilla, Strawberry. 3 bars in a package.' Eventually the vanilla and strawberry flavors would disappear, although there’s evidence that they weren't ever particularly important flavors. A 1933 Notice of Judgment from the Acting Secretary of Agriculture describes a shipment of the treats that was seized in part because "[t]he strawberry and vanilla bars had no recognizable flavor of strawberry or vanilla and the strawberry bars were also artificially colored."

2. AIRHEADS

According to Steve Bruner, who invented the name, he had heard that it takes a generation for a candy name to become part of the collective consciousness—unless it was already a commonly used word. So he asked his children, "What would you call your friend who did something silly?" and one of them came up with 'Airhead.'

3. BUTTERFINGER

Three Butterfinger candy bars.

According to legend, the Curtiss Candy Company of Chicago decided to run a contest to name their new candy bar, and someone suggested 'butterfinger,' a term used in the form "butter-fingered" since the early 17th century to describe someone who lets things fall from their hands.

4. CANDY CORN

In the late 19th century, confections shaped like other things were all the rage (the Candy Professor tells of children then eating candies shaped like cockroaches … for Christmas). Candy corn was invented around this time, and was a stand-out novelty product because real corn kernels—which the candy vaguely resembled—were then mainly a food for livestock, not people.

5. DUM DUMS

Jar of Dum Dums lollipops.
Sarah Browning, Flickr // CC BY-NC 2.0

According to the Spangler Candy Company, the manufacturer, the name Dum Dum was chosen because it "was a word any child could say."

6. HEATH BAR

Two Heath candy bars.
Erika Berlin

In 1914, L.S. Heath decided to buy a candy shop and soda fountain so his children could have a good career. Several years later, the family got hold of the toffee recipe (potential sources range from a traveling salesman to nearby Greek candy makers) that made them famous, especially after they started supplying candy to troops during WWII.

7. HERSHEY'S

Hershey's chocolate bars in a basket.

Milton Hershey had worked for a few years in various candy businesses, but it was in Denver that he came across the caramel recipe that would become a massive hit. Not resting on his laurels, he learned of the new European craze for "milk chocolate" and brought it to the masses in America.

8. HERSHEY'S COOKIES 'N' CREME

Hershey's Cookies 'n' Creme candy bar.
Like_the_Grand_Canyon, Flickr // CC BY-NC 2.0

The candy bar came about in 1994, somewhere around 15-20 years after the ice cream flavor that it was capitalizing on. Where the ice cream comes from is a mystery—claimants range from South Dakota State University to a Blue Bell Creameries employee (to make matters more difficult, many versions of the story have the invention happening after a visit to some anonymous ice cream parlor that put Oreos on their ice cream, and as early as 1959 Nabisco was suggesting that crumbled Oreos in-between layers of ice cream made a great party parfait). No matter the culinary origin, the name origin is generally agreed upon—Nabisco balked at allowing ice cream companies to use their Oreo trademark.

9. HERSHEY'S KISSES

Hershey Kisses on an orange table.
Song Zhen, Flickr // CC BY-NC-ND 2.0

Over 100 years ago, kiss was a generic term for any number of small pieces of confectionery. So when Hershey came out with their product, it was a natural generic name. As years went by and "kiss" lost this particular meaning, Hershey was able to assert control over the name.

10. JOLLY RANCHERS

Bowl of Jolly Rancher candies.
Thomas Hawk, Flickr // CC BY-NC 2.0

When William and Dorothy Harmsen set out to Colorado, their goal was to start a small farm/ranch. Eventually, they decided to open up an ice cream parlor named The Jolly Rancher, evoking both Western hospitality and the Jolly Miller—a hotel in their native Minnesota. The story goes that as sales declined in the winter months, the Harmsens decided to add candies to their menu, which soon outstripped the popularity of all their other offerings.

11. KIT KAT

No one is quite sure where this comes from. The oldest use of the word "kit-cat" in the Oxford English Dictionary is from 1665 to describe a game more commonly known as tipcat, but this is probably coincidence. More likely is that it’s somehow related to the Kit-Cat Club of the early 18th century, which met at a place operated by a mutton pieman named something like Christopher Katt or Christopher Catling. Both he and his pies were named Kit-Kats/Kit-Cats (the prologue to the 1700 play The Reformed Wife even has a line "A Kit-Cat is a supper for a lord"), and the club took its name from either the pie or the pieman.

The jump from a gentleman's club or mutton pie to a candy is more mysterious. A popular theory is that it's related to kit-cat pictures, a type of portrait that the OED describes as "less than half-length, but [includes] the hands." But like most other hypotheses, this doesn't really work because the producer, Rowntree's, registered the name years before there was a candy to go with it, and the candy was originally known as Rowntree’s Chocolate Crisp. Most likely is that someone just liked the name.

12. LIFE SAVERS

Pile of Life Savers candies.
Erika Berlin

The name Life Savers is fairly self-explanatory—they're broadly shaped like a life saver. (Any rumors of the hole existing to prevent a choking death have no merit.)

13. MILKY WAY

Milky Way candy bar.
Like_the_Grand_Canyon, Flickr // CC BY-NC 2.0

Before 1970, Milky Way had a very different connotation. That year, headlines in newspapers across the country blared "FTC Decides Candy Bar Isn't Equal to Milk." The reason for this headline is that the FTC criticized Mars for implying in their advertising things like "Milky Way's nutritional value is equivalent to a glass of milk" and 'That it can and should be substituted for milk." (Odd nutrition claims were nothing new though—early on, Hershey’s advertised their chocolate bars as being "more sustaining than meat.")

While the galaxy certainly helped with the name, the original focus of the Milky Way was about how "milky" it was, and specifically that it was milkier than a malted milk you could get at a soda fountain.

14. M&M's

The two Ms stand for Mars and Murrie. This Mars was Forrest Mars, the son of Mars candy company founder Frank Mars. Forrest and Frank had a falling out, which resulted in Forrest going to Europe and founding his own candy company (many years later, he would return to take over Mars, Inc after his father's death).

How he came up with the idea for M&M's is a bit mysterious (with versions ranging from wholesale ripoff to inspiration during the Spanish Civil War), but is generally related to a candy-covered British chocolate called Smarties (unrelated to the American Smarties). When Forrest Mars returned to the United States to make these candies, he recognized that he needed a steady supply of chocolate. At the time, Hershey was a major supplier of chocolate to other businesses and was run by a man named William Murrie. Forrest decided to go into business with William's son, Bruce (which long rumored to be a shameless ploy by Forrest to ensure a chocolate supply during World War II), and they named the candy M&M's.

15. MR. GOODBAR

Bowl of Mr. Goodbar candy bars.
Erika Berlin

According to corporate history, Hershey chemists had been working on a new peanut candy bar. As they were testing it, someone said "that's a good bar" which Milton Hershey misheard as "Mr. Goodbar."

16. REESE'S PEANUT BUTTER CUPS

Stack of Reese's Peanut Butter Cups.
Sheila Sund, Flickr // CC BY-NC 2.0

Harry Burnett Reese started working for the Hershey Chocolate Company in 1916 as a dairy farmer, but after leaving and returning to Hershey's a few times over the following years, Reese set out on his own. His great peanut butter cup invention was supposedly inspired by a store owner who told him that they were having difficulties with their supplier of chocolate-covered peanut butter sweets.

17. SKITTLES

Bags of Skittles in a vending machine.

Skittles originated in the United Kingdom, where "skittles" is a type of bowling, either on lawns or on a tabletop in pubs. The phrase "beer and skittles" emerged to describe pure happiness (now more commonly seen in "life is not beer and skittles"). So the name for the candy likely emerged to associate it with fun.

The candy bar was named after the Mars family horse. The Mars family was very into horses, even naming their farm the Milky Way Farm—which produced the 1940 Kentucky Derby champion Gallahadion.

Originally called Mars Men, the Sour Patch Kid was renamed to capitalize on the popularity of the '80s craze of Cabbage Patch Kids.

The Toblerone is a portmanteau of the candy inventor—Theodor Tobler—and torrone, a name for various Italian nougats. As for the distinctive triangle shape, it's generally credited to the Swiss Alps, but Toblerone’s UK site suggests something a little racier—"a red and cream-frilled line of dancers at the Folies Bergères in Paris, forming a shapely pyramid at the end of a show.”

21. TOOTSIE ROLL

The official story is that in the late 19th century, Leo Hirschfeld invented the Tootsie Roll—Tootsie coming from his daughter's nickname. But the Candy Professor has blown multiple holes in the official story, finding evidence from patents to trademark filings that show Tootsie Rolls came into existence circa 1907. And as for the Tootsie? The Candy Professor has also found that the company that applied for those trademarks had an earlier product called Bromangelon that had as a mascot the character "Tattling Tootsie." Whether this Tootsie was named after Hirschfeld’s daughter or something mysterious is still debated.

22. TWIX

The meaning behind Twix has been lost to time (and marketing). But the general consensus is that it's a portmanteau of twin and sticks (stix), or possibly twin and mix.

23. TWIZZLERS

Another term where the true origin is unknown, but it’s certainly related to the word twizzle, which dates back to the 18th century. One of the definitions the Oxford English Dictionary gives is "To twirl, twist; to turn round; to form by twisting."

24. YORK PEPPERMINT PATTIES

The popular patties were originally created by the York Cone Company out of York, Pennsylvania, which made ice cream cones before going all in on their new invention. As for the "Peanuts" character Peppermint Patty, Charles Schulz said that the name inspiration was "A dish of candy sitting in our living room." But as the York version was still regional at the time, the inspiration was probably a different peppermint patty.

25. BABY RUTH

A debate for the ages. Otto Schnering named the bar after either Ruth Cleveland, daughter of President Grover Cleveland (whose New York Times obituary said, "She was known to the Nation as 'Baby Ruth' while she was a child in the White House") or Babe Ruth, the famous baseball player. While Baby Ruth was a very popular name (and not just for Presidential daughters. An actress at the time of the candy bar’s introduction was known as "Baby" Ruth Sullivan), Babe Ruth proponents point out that Cleveland’s daughter died in 1904, around 17 years before the candy was introduced. But claims of a recently discovered court document has Schnering answering under oath the question "When you adopted the trade mark Baby Ruth…did you at that time [take] into consideration any value that the nickname Babe Ruth…might have?”

Schnering responded, "The bar was named for Baby Ruth, the first baby of the White House, Cleveland, dating back to the Cleveland administration…There was a suggestion, at the time, that Babe Ruth, however not a big figure at the time as he later developed to be, might have possibilities of developing in such a way as to help our merchandising of our bar Baby Ruth."

In the latest story, the headstrong pigeon pivots to something it very much does not want to do—go to school.

A high-spirited, unique squirrel named Taco provides color commentary on regular squirrel facts in This Is a Taco!, a book that is much more than a factual guide to squirrels. In it, Taco embellishes, acts out, and sometimes completely changes the facts to be truer to his personal experience as a squirrel, which involves being opinionated and eating lots of tacos.
