Most parts of the country will be losing an hour this weekend (or "springing forward," if your glass is half-full) when clocks are reset for Daylight Saving Time. And while this means there will be some appreciated extra sunlight in the evenings, early risers are likely already dreading Sunday morning. Here are 10 things you should know before making the biannual change.

1. BENJAMIN FRANKLIN WAS HALF JOKING WHEN HE SUGGESTED IT.

More than a century before Daylight Saving Time (DST) was adopted by any major country, Benjamin Franklin proposed a similar concept in a satirical essay. In a piece called "An Economical Project for Diminishing the Cost of Light," published in The Journal of Paris in 1784, he argued:

All the difficulty will be in the first two or three days; after which the reformation will be as natural and easy as the present irregularity [...] Oblige a man to rise at four in the morning, and it is more than probable he will go willingly to bed at eight in the evening; and, having had eight hours sleep, he will rise more willingly at four in the morning following.

In one prophetic passage, he pitched the idea as a money-saver (though at the time people would have been conserving candle wax rather than electricity). To enforce the out-there plan, Franklin suggested taxing shutters, rationing candles, banning non-emergency coach travel after dark, and firing cannons at sunrise to rouse late-sleepers. While his essay clearly brought up some practical points, Franklin may have originally written it as an excuse to poke fun at the French for being lazy. He wrote that the amount of sunlight that goes wasted each morning would likely come as a shock to readers who "have never seen any signs of sunshine before noon."

2. OFFICIAL CREDIT FOR THE IDEA GOES TO A BUG COLLECTOR.

The first serious case for DST came from a peculiar place. While working at a post office by day, an entomologist named George Vernon Hudson, who did most of his bug hunting at night, soon became frustrated by how early the sun set during the summer months. He reasoned that springing the clocks forward would allow more daylight for bug collecting—along with other evening activities. The clocks could be switched back in the winter when people (and bugs) were less likely to be found outdoors.

When the idea was proposed to a scientific society in New Zealand in 1895 it was panned for being pointless and overly complicated. Just two decades later, Daylight Saving Time would begin its spread across the developed world.

3. WWI PUSHED DAYLIGHT SAVING INTO LAW.

In 1916, Germany became the first country to officially adopt Daylight Saving Time. It was born out of an effort to conserve coal during World War I, and Britain, along with many other European nations, was quick to follow the Germans' lead. It wasn't until 1918 that the time change spread to the U.S. A year after entering the war, America began practicing DST as an electricity-saving measure. Most countries, including the U.S., ceased nationwide observation of the switch following wartime. Until, that is …

4. IT GAINED RENEWED POPULARITY DURING THE ENERGY CRISIS.

Although it was already being practiced in many states, the U.S. reconsidered nationwide DST in the 1970s, when, once again, the argument pivoted back to energy conservation. The oil embargo of 1973 had kicked off a nationwide energy crisis and the government was looking for ways to reduce public consumption. Year-round Daylight Saving Time was imposed in the beginning of 1974 to save energy in the winter months. Not everyone was enthusiastic about the change: Some of the harshest critics were parents suddenly forced to send their children to school before sunrise.

5. IT MAY ACTUALLY BE AN ENERGY WASTER.

Despite Daylight Saving Time's origins as an energy saving strategy, research suggests it might actually be hurting the cause. One 2008 study conducted in Indiana found that the statewide implementation of DST two years earlier had boosted overall energy consumption by one percent. While it's true that changing the clocks can save residents money on lighting, the cost of heating and air conditioning tends to go up. That extra hour of daylight is only beneficial when people are willing to go outside to enjoy it.

6. IT'S ALSO A HEALTH HAZARD.

Even if DST was good for your energy bill, that wouldn't negate the adverse impact it can have on human health. Numerous studies show that the extra hour of sleep we lose by springing ahead can affect us in dangerous ways. An increased risk of heart attack, stroke, and susceptibility to illness have all been linked to the time change.

7. BUT THERE ARE SOME BENEFITS.

Though people love to complain about it, Daylight Saving Time isn't all bad news. One notable benefit of the change is a decrease in crime. According to one study published in 2015, daily incidents of robbery dropped by seven percent following the start of DST in the spring. This number was heavily skewed by a 27 percent dip in robberies during the well-lit evening hours.

8. IT'S NOT OBSERVED NATIONWIDE.

DST has been widely accepted across the country, but it's still not mandated by federal law. U.S. residents resistant to springing forward and falling back each year might consider moving to Arizona. The state isn't exactly desperate for extra sunlight, so every spring they skip the time jump. This leaves the Navajo Nation, which does observe the change, in a peculiar situation. The reservation is fully located within Arizona, and the smaller Hopi reservation is fully located within the Navajo Nation. The Hopi ignores DST like the rest of Arizona, making the Navajo Nation a Daylight Saving doughnut of sorts, suspended one hour in the future for half the year.

9. IT STARTS AT 2 A.M. FOR A REASON.

Daylight Saving Time doesn't begin at the stroke of midnight like you might expect it to. Rather, the time change is delayed until most people (hopefully) aren't awake to notice it. By waiting until two in the morning to give or take an hour, the idea is that most workers with early shifts will still be in bed and most bars and restaurants will already be closed.

10. THE CANDY INDUSTRY LOBBIED FOR AN EXTENSION.

Until recently, losing an hour of daylight in the fall presented a problem for the candy industry. That's because Daylight Saving Time traditionally ended on the last Sunday in October, a.k.a. before Halloween night. Intense lobbying to push back the date went on for decades. According to one report, candy lobbyists even went so far as to place tiny candy pumpkins on the seats of everyone in the Senate in 1986. A law extending DST into November finally went into effect in 2007.

8 Tips for Interviewing a Serial Killer, According to Famed FBI Profiler John Douglas

Over the course of his career, former FBI agent and behavioral analyst John E. Douglas has interviewed criminals ranging from repeated hijacker Garrett Trapnell and cult leader Charles Manson to serial killers Edmund Kemper (a.k.a. the Co-Ed Killer) and Dennis Rader (a.k.a. B.T.K.). In his new book, The Killer Across the Table, Douglas takes readers into the room as he interviews four very different offenders.

In these conversations, “I'm trying to gain [their] trust [to get] information that I'll be able to apply to current cases,” Douglas tells Mental Floss. Here, he outlines how he prepares for an interview with a killer to figure out what makes them tick.

1. Never go into an interview cold.

“Preparation is the number one factor for a successful interview” of this kind, Douglas says. “Before I go in to do an interview, [I] go back into the files and fully look at the case that got him or her incarcerated to begin with. Which means looking at the police reports, the preliminary protocol that the medical examiner did regarding the autopsy, autopsy photographs, and then looking in the corrections reports as well. You want to be totally armed with the case when you go in.”

2. Memorize everything—don’t use notes or a tape recorder.

Early on in his interviews with killers, Douglas used a tape recorder, which he now says was a mistake. “You're dealing with very paranoid individuals. They don't trust you, they don't trust the [corrections] system,” he says. “If my head is down, [they’ll ask], ‘What, are you taping this? Why are you writing these notes down?’” Memorizing the case is key—when he goes in, he won’t have notes or a tape recorder: “It's going to be key [for] me to maintain some eye contact with them.”

3. Make sure the environment is right.

The key in these interviews, Douglas says, is to make the environment feel open so that the killer feels comfortable and like he’s in control. “When you go into a prison, sometimes you're forced to deal with what you've got,” he says. “But if I have time, I try to [make arrangements] depending on the personality.”

Douglas prefers to conduct his interviews at night, relying only on low table lights to create a soothing, stress-free atmosphere. Douglas will even think about seating arrangements. “If I'm dealing with a real paranoid type of individual, I need to put this person near a window—if there's a window—so that he can look out the window and psychologically escape, or I may have him face a door,” he says. Both Charles Manson and Richard Speck chose to sit on the backs of their chairs so they could look down on him. Douglas’s attitude is: “You hate me. I know you hate me, but go ahead and do it. I'm just trying to get a little bit of information now.”

4. Don’t rely on what a killer tells you.

Douglas never takes a killer’s word for anything, which is why memorizing the case is so important. Typically, he knows the answers to the questions he’s asking, and it allows him to call out the offender if he or she lies. “If you don't look deeply into the material, you don't know who in the heck you're talking to,” Douglas says. “You're talking to somebody who's pulling the wool over your eyes … If [an interviewer relies] on self-reporting, they're going to be filled with a lot of lies coming from the person they're interviewing.”

5. Know that this is not an interrogation.

Once he knows who’s committed a crime, Douglas says, his main goal is to find out what motivated them. The best way to get that out of them is to ask his questions “in a very relaxed kind of a format, making the subject—even if it's a guy like Manson or some of the worst killers you'd ever want to meet—feel real comfortable and feel at the same time that they are controlling me during the interview.”

What Douglas ultimately tries to do is have a conversation with the offender. “That means if they're asking me a lot of questions about myself, about maybe my family, my job, and I'm pretty honest with them,” he says. “They will trust me and open up to me as long as they know that I know the case, backwards and forwards. If they start fudging on the case trying to send me down the wrong path, I will confront them, but not in mean [way]. I'll laugh and say, ‘Look, come on. I know what you did. What are you doing here?’ That’s how you gain their trust.”

6. Be mindful of your body language—and the actual language you’re using.

When he’s in an interview, Douglas isn’t sitting there with his arms crossed, looking uncomfortable. “The body language should be just relaxed, not a defensive kind of posture,” he says. “[It should be] very comfortable—like on a date kind of thing.”

Douglas also avoids words like killing, murder, and rape, and, as awful as it might sound, avoids placing the blame on the killer. “I'm trying to get him to talk so we're going to project the blame," Douglas says. "[Some killers] use this projection, never accepting responsibility, not admitting that it was free will, that they had the ability to make choices and they made the wrong choices in their lives, even though they may have come from a very, very bad background.”

This kind of approach is what helped Douglas gain insights from Ed Kemper. When Douglas asked how Kemper—who was 6 feet, 9 inches tall and 300 pounds—would get young women in his car, Kemper revealed that he would pull up next to them and look at his watch, which would give them the impression that he had somewhere to be. “I’ll go with this guy. He’s got an appointment, nothing’s going to happen to me,” Douglas says. “Just a little thing like that was real helpful to me.”

7. Play it cool, no matter what happens.

Being confrontational is no way to get a killer to open up. “In an interview, whether it's a serial killer or any type of violent offender, I'll never challenge them or be negative toward them,” Douglas says. “I'll never do anything like that. If I feel that they're not being truthful, I'll bring it to their attention. But I’m on a fact-finding mission. There are several shows on television right now where celebrity types are going into prisons doing interviews. They get in the guy's face and they call him a liar. [So] the guy, what does he want to do? ‘I want to go back to my cell. Screw you. I'm out of here.’ And you can't hold him there—he's got to go back. So, you never do anything like that.”

8. Don’t be afraid to feign empathy.

Sometimes getting what you need out of an offender means fudging the truth. Sometimes Douglas will tell the killer that he’s earning points with the warden by doing the interview. “There's still always this glimmer of hope that they'll get out of prison one day, even if they're in there for multiple murders,” he says. “The warden doesn't give a damn about him, but I'm just telling them this to try to get him to speak up.”

Sometimes Douglas will play to his subject's pride and narcissism. “They want to be the big daddy,” he says. "'But I'm the main guy, right? You're doing this research and you guys got the real McCoy here. I'm the best and the worst of the worst.'" And sometimes, he feigns empathy—all with the goal of finding out information that will help prevent and solve other crimes.

"Let the person feel they are in control of the interview,” Douglas says. "Be open with yourself. Give them information about yourself to this person and it should go well."

14 Secrets of McDonald's Employees

While there’s virtually no end to the number of fast food options for people seeking a quick meal, none have entered the public consciousness quite like McDonald’s. Originally a barbecue shop with a limited menu when it was founded by brothers Richard and Maurice McDonald in the 1940s, the Golden Arches have grown into a franchised behemoth with more than 36,000 locations worldwide.

Staffing those busy kitchens and registers are nearly 2 million McDonald's employees. To get a better idea of what many consider to be the most popular entry-level job in the nation—staff members on the floor make an average of $9 an hour—we asked several workers to share details of their experiences with errant ice cream machines, drive-through protocols, and special requests. Here’s what they had to say about life behind the counter.

1. McDonald's employees can't always deliver fast food all that fast.

While McDonald’s and other fast-service restaurants pride themselves on getting customers on their way, some menu items just don’t lend themselves to record service times. According to Bob, an assistant store manager at a McDonald’s in the Midwest, pies take an average of 10 to 12 minutes to prepare; grilled chicken, 10 minutes; and biscuits for Egg McMuffins, eight to 10 minutes. In the mood for something light, like a grilled chicken and salad? That will take a few minutes, too. Bob says salads are pre-made with lettuce but still need to have chicken and other ingredients added.

The labor-intensive nature of assembling ingredients is part of why the chain has more recently shied away from menu items with too many ingredients. “We are trained to go as fast down the line as we can, and if we have to stop to make something that has 10 ingredients, it tends to slow things down,” Bob tells Mental Floss. “Corporate has realized this and has taken many of these items off in recent years, [like] McWraps, Clubhouse, more recently the Smokehouse and mushroom and Swiss and moved to items that can go a lot quicker.”

2. McDonald's workers wish you’d stop asking for fries without salt.

A common “trick” for customers seeking fresh fries is to ask for them without salt. The idea is that fries that have been under a heating lamp will already be salted and that the employee in the kitchen will need to put down a new batch in the fryer. This does work, but customers can also just ask for fresh fries. It’s less of a hassle and may even save employees some discomfort.

“People can ask for fresh fries and it's actually way easier to do fresh fries rather than no-salt fries,” Andy, an employee who’s worked at three different McDonald’s locations in the Midwest, tells Mental Floss. “For those, we have to pour the fries onto a tray from the fryer so they don't come in contact with salt. It can get awkward sometimes getting everything into position, especially if you have a lot of people working in close proximity and it's busy, so I've had some scalded hands a couple of times trying to get fries out in a timely way.”

3. McDonald's workers have to pay careful attention to the order of ingredients.

McDonald’s is pretty specific about how their burgers and other items are supposed to be assembled, with layers—meat, cheese, sauce—arranged in a specific order. If they mess it up, customers can notice. “In some cases it has a big impact,” Sam, a department manager and nine-year veteran of the restaurant in Canada, tells Mental Floss. “Like placing the cheese between the patties with a McDouble. If they don’t put the cheese between the patties, the cheese won’t melt.”

4. There’s a reason McDonald’s employees ask you to park at the drive-through.

After ordering at the drive-through window, you may be slightly puzzled when a cashier asks you to pull into one of the designated parking spots. That’s because employees are measured on how quickly they process cars at the drive-through. If your order is taking a long time to prepare, they’ll take you out of the queue to keep the line moving. “My store has sensors in the drive-through that actually tell us exactly how long you are at each spot in the drive-through,” Bob says. “We get measured based on something we call OEPE. Order end, present end. [That measures] from the second that your tires move from the speaker until your back tires pass over the sensor on the present window. My store is expected to be under two minutes.” If an order will take longer than that, you'll be asked to park.

5. The McDonald's drive-through employees can hear everything going on in your car.

While the quality of the speakers at a drive-through window can vary, it’s best to assume employees inside the restaurant can hear everything happening in your car even before you place an order. “The speaker is activated by the metal in the car, so as soon as you drive up, the speaker turns on in our headset,” Andy says. “We can hear everything, and I do mean everything. Loud music, yelling at your kids to shut up, etc.”

6. The employees at McDonald’s like their regulars.

With hot coffee, plenty of tables, Wi-Fi, and newspapers, McDonald’s can wind up being a popular hang-out for repeat customers. “[We have] a ton of regulars who come into my store,” Bob says. “I'd say at least 75 percent of my daily customers know us all by name and we know them all, too. It makes it nice and makes the service feel a lot more personal when a customer can walk into my location, and we can look them in the eye and say, ‘Hey Mark! Getting the usual today?’ and we've already started making his coffee exactly how he takes it.”

7. McDonald’s staff get prank calls.

Unless they’re trying to cater an event, customers usually don’t have any reason to phone a McDonald’s. When the phone rings, employees brace themselves. In addition to sometimes being asked a legitimate question like when the store closes, Sam says his store gets a lot of prank calls. “Sometimes it’s people asking about directions to Wendy’s,” he says. “A lot of inappropriate ones. Most are pretty lame.”

8. For a McDonald’s worker, the ice cream machine is like automated stress.

The internet is full of stories of frustrated McDonald’s customers who believe the chain’s ice cream machines are always inoperable. That’s not entirely true, but the machine does experience a lot of downtime. According to Bob, that’s because it’s always in need of maintenance. “The thing is, it is a very sensitive machine,” he says. “It's not made to be making 50 cones in a row, or 10 shakes at a time. It takes time for the mix to freeze to a proper consistency. It also requires a daily heat mode, [where] the whole machine heats up to about 130 degrees or so. The heat mode typically takes about four hours to complete, so you try to schedule it during the slowest time.” Stores also need to take the machine entirely apart every one to two weeks to clean it thoroughly.

Bob adds that the machine’s O-rings can crack or tear, rendering the unit inoperable. Seasoned workers can tell if a unit is faulty by the consistency of the shakes or ice cream coming out, and sometimes by the noises it makes.

9. McDonald's employees don't mind if you order a grilled cheese.

Contrary to rumor, there’s no “secret menu” at McDonald’s. But that doesn’t mean you can’t sometimes snag something not listed on the board. Andy says a lot of people order a grilled cheese sandwich. “I've made many a grilled cheese before,” he says. But it’s not without consequences. “Sometimes it can get a bit risky doing it because the bun toaster wasn't designed to make grilled cheeses so sometimes you get some burnt buns or cheese or the cheese sticks inside and it slows down the other buns from getting out on time so that causes more burnt buns.”

Another common request is for customers to ask for a McDouble dressed as a Big Mac, with added Big Mac sauce and shredded lettuce. “I think [it’s] a way more practical way to eat a Big Mac since there's less bun in the way, and it's also way cheaper even if you do get charged for Mac sauce.”

10. McDonald’s workers recommend always checking your order.

Nothing stings worse than the revelation that an employee has forgotten part of your food order. Contrary to popular belief, it’s not because the employees are being lazy or inattentive. According to Bob, it’s simply due to the volume of customers a typical location has to process in a given day. “We are human,” he says. “Mistakes do happen. We always feel terrible when they do but when we serve 1000-plus people a day, it's bound to happen.”

Bob recommends checking your bag before leaving the restaurant and not taking it personally if there’s an issue. “Be nice to us if you have a problem,” he says. “It's a huge difference between coming to us and saying, ‘Hey, I seem to be missing a fry from my bag,’ and ‘You bastards didn't give me my fries!’” If you want to check your bag at the drive-through, though, he recommends trying to pull ahead so cars behind you can move forward.

11. McDonald's employees don't recommend the grilled chicken.

If a menu item isn’t all that popular, it can wind up experiencing a low rate of turnover. Of all the food at McDonald’s, the most neglected might be the grilled chicken. Because it doesn't move quickly, workers find that it can turn unappetizing in a hurry. “That stuff has a supposed shelf life of 60 minutes in the heated cabinet, but it dries out so quickly that even if it's within an acceptable time frame, it looks like burnt rubber, and probably tastes like it, too,” Andy says.

12. Golden Arches employees aren’t crazy about Happy Meal collectors.

Happy Meals are boxed combos that come with a toy inside. Usually, it’s tied into some kind of movie promotion. That means both Happy Meal collectors and fans of a given entertainment property can swarm stores looking for the product. “The biggest pain involving the Happy Meals is the people who collect them,” Bob says. “I personally hate trying to dig through the toys looking for one specific one. We usually only have one to three toys on hand. It's especially a pain in the butt during big toys events such as the Avengers one we just had. There was like 26 different toys, and some customers get really mad when you don't have the one that they want.”

And no, employees don’t usually take home leftover toys. They’ve saved for future use as a substitute in case a location runs out of toys for their current promotion.

13. McDonald's employees can’t mess with Monopoly.

The McDonald’s Monopoly promotion has been a perennial success for the chain, with game pieces affixed to drink cups and fry containers. But if you think employees spend their spare time peeling the pieces off cups looking for prizes, think again. Following a widely-publicized scandal in 2000 that saw an employee of the company that printed the pieces intercepting them for his own gain, the chain has pretty strict rules about the promotion. “Monopoly pieces and things like them get sent back to corporate,” Bob says. “We aren't allowed to touch them, open them, or redeem them as employees.”

14. One McDonald's worker admits there have been sign mishaps.

Many McDonald’s locations sport signs under the arches advertising specials or promotions. Some are analog, with letters that need to be mounted and replaced. Others have LED screens. Either way, there can be mistakes. “I've never seen anyone mess around with the letters,” Andy says. “But I do remember one time we were serving the Angus Burgers and the ‘G’ fell off of the word ‘Angus.’ Good times.”
