The world’s most famous dinosaur is a lot more interesting than many people realize. Some 65 million years after its extinction, Tyrannosaurus rex is still captivating scientists, movie makers, and the general public alike. Here’s some neat stuff you might not know about the “tyrant lizard king.”

1. Those Arms Weren’t So Puny After All.

T. rex’s supposedly wimpy arms have become a prehistoric punch line, but according to paleontologist Jack Conrad, this misconception needs to go extinct. “The bicep alone—and this is a conservative estimate—could curl 430 pounds,” he said.

2. Adult Rexes Might’ve Been Covered In Feathers

Fluffy dinosaur skeletons are nothing new, but until recently many assumed feathers were the exclusive property of smaller dinosaur species. That all changed with the discovery of Yutyrannus huali in 2012. This Chinese T. rex relative reached an impressive length of over 25 feet and sported six-inch feathers which covered much of its body. The find has raised the very serious possibility that the Tyrannosaurus might have had some fuzzy feathers of its own.

3. T. rex Was Almost Re-Named Manospondylus gigas

“Manospondylus gigas” doesn’t exactly roll off the tongue. However, the rules of scientific naming usually dictate that the discoverer of a new species earns the naming rights. This caused a brief debate when it was revealed in 1999 that fossil hunter Edward Drinker Cope had unearthed a T. rex vertebrae, which he dubbed “Manospondylus gigas,” some 13 years before the word “Tyrannosaurus” was ever coined. Some scientists felt that “M. gigas” should replace “T. rex” as the dino’s official moniker. The International Commission on Zoological Nomenclature (ICZN), which dictates such matters, later ruled that because “Tyrannosaurus rex” had been a valid name for over 50 years, it warranted special protected status.

4. T. rex Had Excellent Vision

The lizard king had darn good eyesight by dinosaur standards thanks to special adaptations in its skull. Like humans and birds of prey, T. rex had “binocular vision,” meaning its eyes looked directly forward and their planes of vision overlapped, enhancing the beast’s depth perception capabilities.

5. Tyrannosaurs May Have Practiced Cannibalism

Over the years, many Tyrannosaurus skeletal remains have been found with tell-tale bite marks that most likely came from other T. rexes, although it’s impossible to determine if this was the result of scavenging or predation.

6. Juveniles Grew Up Quick

Talk about a teenage growth spurt. Research conducted in 2004 indicates that between ages 14 and 18, young “rexes” would gain a whopping five pounds per day.  

7. A Prime Specimen Was Once Sold For Over $8 Million

The whirlwind saga of “Sue” the T. rex (nicknamed in honor of paleontologist Sue Hendrickson) still sends shockwaves throughout the paleontological community. Her skeleton was over 90 percent complete, a true rarity by fossilization standards—which was made all the more unlikely by Sue’s immense size (she was roughly 42 feet long from end to end). Her discovery prompted an intense legal battle which resulted in the Tyrannosaurus being put up for auction in 1997. The Chicago Field Museum teamed up with McDonald’s and the Disney Corporation to bring her to the Windy City at a cost of $8.36 million, keeping this one-of-a-kind specimen available to the public.

8. The Chase Scene in Jurassic Park Probably Couldn’t Have Happened

In the film, a Tyrannosaurus is seen charging at 45 miles per hour in hot pursuit of a jeep. Thrilling as this scene was, in order for such a massive animal to reach those speeds, 86 percent of its muscle content would have to be concentrated in its legs, an anatomical impossibility.  For more, check this out.

9. Contrary to What You Might’ve Heard, T. rex Was, In All Likelihood, Both a Hunter and a Scavenger

“Was T. rex a ferocious hunter or a lowly scavenger?” is an oft-asked dino question, much to the chagrin of many paleontologists. Most modern carnivores dine on carcasses and live prey alike, and—despite sensationalist headlines like this one—there’s no reason to assume that Tyrannosaurus didn’t behave likewise. As science writer Brian Switek recently put it, “there was never any legitimate debate on this point. Our beloved T. rex was undoubtedly a predator and a scavenger, and the ongoing fascination with the dinosaur’s reputation has a lot more to do with muddled media than science.”

10. The World’s First Known T. rex Footprint Might Have Been Found At A Boy Scout Camp

Unless a prehistoric animal literally dies in its tracks, we can’t determine the exact identity of its maker when a fossilized footprint is discovered. However, a gigantic footprint was unearthed at the Philmont Boy Scout Ranch in northern New Mexico in 1983 by geologist Charles Pillmore. Because of its striking similarities to the T. rex's distinctive feet, the scientific community has tentatively concluded that it was most likely produced by an adult Tyrannosaurus.

11. Buffalo, South Dakota is the Self-Described “T. rex Capital of the World”

At least seven T. rex skeletons have been unearthed near this sleepy town of 330. Notable Buffalo rexes include a large specimen affectionately called “Stan” and a famous individual known as “Samson,” which was briefly put up for sale on eBay (though it failed to meet the sellers’ multi-million-dollar asking price).

When both parties weigh several tons, consummating a relationship can be a daunting task. Located in northern Spain, the Jurassic Museum of Asturias features a series of extensive dinosaur exhibits, one of which includes two Tyrannosaurus skeleton replicas mounted in a very speculative sex position.

10 Surprising Facts About Mr. Mom
Shout! Factory
Shout! Factory

John Hughes penned the script for 1983's Mr. Mom, a comedy about a family man named Jack Butler (Micheal Keaton) who loses his job. To ensure their three kids are taken care of, his wife, Caroline (Teri Garr), goes back to work—leaving Jack to fight off a vacuum cleaner and learn why it's never a good idea to feed chili to a baby.

In 1982, Keaton turned in a star-making role in Ron Howard’s Night Shift, but Mr. Mom marked the first time he headlined a movie, and it launched his career. Hughes had written National Lampoon's Vacation, which—oddly enough—was released in theaters the weekend after Mr. Mom. But Hughes himself was still a relative unknown, as it would be another year before he entered the teen flick phase of his career, which would make him iconic.

In the meantime, Mr. Mom hit home for a lot of viewers, as the economy was on the downturn and more and more women were entering (or reentering) the workforce. But some people think that the movie's ending—which sees the couple revert to traditional gender roles—sidelined the movie's message. Still, on the 35th anniversary of its release, Mr. Mom remains an ahead-of-its-time comedy classic.

1. IT'S BASED ON A TRUE STORY.

Mr. Mom producer Lauren Shuler Donner came across a funny article John Hughes had written for National Lampoon. Based on that, she contacted him and the two became friends. “One day, he was telling me that his wife had gone down to Arizona and he was in charge of the two boys and he didn’t know what he was doing,” Donner told IGN. “It was hilarious! I was on the floor laughing. He said, ‘Do you think this would make a good movie?’ And I said, ‘Yeah, this is really funny.’ So he said, ‘Well, I have about 80 pages in a drawer. Would you look at it?’ So I looked at it and I said, ‘This is great! Let’s do it!’ We kind of developed it ourselves.” In the book Movie Moguls Speak, Donner mentioned how Hughes “had never been to a grocery store, he had never operated a vacuum cleaner. John was so ignorant, that in his ignorance, he was hilarious.”

The players involved with the movie told Donner and Hughes they thought it should be a TV movie. Hughes had a TV deal with Aaron Spelling, who came aboard to executive produce. “Then the players involved were upset because John was writing out of Chicago instead of L.A.,” Donner said in Movie Moguls Speak. “They fired John and brought in a group of TV writers. In the end, John and I were muscled out. It was a good movie, but if you ever read John’s original script for Mr. Mom, it’s far better.”

2. JOHN HUGHES REJECTED THE IDEA OF DIRECTING MR. MOM.

Stan Dragoti ended up directing the film, but only after Hughes turned it down, because he preferred to make his movies in Chicago, not Hollywood. “I don’t like being around the people in the movie business,” Hughes told Roger Ebert. “In Hollywood, you spend all of your time having lunch and making deals. Everybody is trying to shoot you down. I like to get my actors out here where we can make our movies in privacy.” Hughes remained in Chicago and filmed his directorial debut, Sixteen Candles, there.

3. MICHAEL KEATON GOT THE ROLE BECAUSE OF NIGHT SHIFT.

In 1982’s Night Shift, Keaton’s character works at a morgue and starts a prostitution ring with co-worker Henry Winkler. Donner had an agent friend, Laurie Perlman, who represented the not-yet-famous actor. She contacted Donner and pitched Keaton to her. “’Look, I represent this guy who is really funny. Would you meet with him?’" Donner recalled of the conversation. "So I met with him. Usually I don’t like to do this unless we’re casting, but I met with him because she was my friend. And then she said, ‘You have to see this movie Night Shift that he’s in.’ So I went to see Night Shift, and midway through I couldn’t wait to get out of that theater to give Mr. Mom to Michael Keaton. Fortunately, he liked it."

Keaton told Grantland that he turned down one of the main roles in Splash to play Jack Butler. “I just remember at the time thinking I wanted to get away from what I’d just done on Night Shift,” he said. “I thought if I do it again, I might get myself stuck. So then Mr. Mom came along. So I said no [to Splash] so I could set up this framework right away where I could do different things.”

4. THE FILM BROKE NEW GROUND.

In 1983, more women stayed at home than worked, so it was a novelty for a man to be a stay-at-home dad. Today, an estimated 1.4 million men are stay-at-home dads, and 7 million men are their children's primary caregiver. “Mr. Mom became part of the vernacular,” Donner told Newsweek. “Mr. Mom represented a segment of men who were at home dealing with the kids who, up until then, really hadn’t been heard from. That’s what really told me about the power of film, because it spoke for a lot of men. It also helped women, because I think that women sometimes, if you’re a housewife, you’re not really appreciated for what you do. This sort of made women feel better about what they did because they knew that men were understanding it.”

5. TODAY, “MR. MOM” IS CONSIDERED A PEJORATIVE TERM.

More than 30 years after the film’s release, stay-at-home dads feel the term “Mr. Mom” should die. The National At-Home Dad Network launched a campaign to terminate the phrase and instead have people refer to men as “Dad.” In 2014 Lake Superior State University voted to banish “Mr. Mom” from the lexicon.

“At least, the pop-culture image of the inept dad who wouldn’t know a diaper genie from a garbage disposal has begun to fade,” wrote The Wall Street Journal, after declaring “Mr. Mom is dead.”

6. TERI GARR DIDN’T KNOW IT WAS A MESSAGE MOVIE.

The movie redefined gender roles, but when the producers pitched the premise to Garr, they hid the plot reversal. “They just told me it was about a guy who does the work that a woman does, because it’s so easy,” she told The A.V. Club. “And I went, ‘Oh, yeah. Ha ha.’ It’s so easy. All the women I know who stay home and take care of their kids, they go, ‘Oh yeah, this is easy.’ Hmm.”

7. MARTIN MULL IMPROVISED THE “220, 221” LINE.

The quote everyone remembers from the movie comes from Jack, holding a chainsaw, standing next to Ron Richardson (Martin Mull) and discussing what kind of wiring Jack will use in renovating the house: “220, 221, whatever it takes,” Jack says.

“We’re doing the scene and it was okay,” Keaton told Esquire. “And I remember saying to the prop guy, ‘Go find me a chainsaw.’ When he comes back with it, he says, ‘You wanna wear these?’ And he holds up some goggles. I go, ‘Yeah.’ You know, they make me look crazy. And when Martin shows up, I know I should look under control, I’m not sweating it. I’m a dude. So we’re standing there, Martin pulls me aside and says, ‘You know what you ought to say? When I ask about the wiring, you oughta just deadpan: ‘220, 221.’ I died. It was perfect. I may have added ‘whatever it takes.’ But it was his.”

“That was a little ad-lib that we just threw in, but every carpenter or construction person I’ve ever worked with, they’re always quoting that line from Mr. Mom,” Mull told The A.V. Club.

8. MR. MOM OUTGROSSED HUGHES’S OTHER 1983 SUMMER MOVIE—VACATION.

Mr. Mom only opened on 126 screens on July 22, 1983, but managed to gross $947,197 during its opening weekend. Once the film went wide a month later to 1235 screens, it hit number one at the box office and spent five weeks at the top. By the end of its run, the film had grossed just shy of $65 million, making it the ninth highest-grossing film of 1983 (just between Staying Alive and Risky Business). National Lampoon’s Vacation, Hughes’s other film that summer, came out July 29 and ended its theatrical run with $61,399,552 (at its height, it showed on 1248 screens). Vacation finished the year in 11th place.

9. THE MOVIE LED TO HUGHES BEING CALLED “A PURVEYOR OF HORNY SEX COMEDIES.”

During a 1986 interview with Seventeen magazine, Molly Ringwald asked the writer-director why he never showed teen sex in Sixteen Candles or The Breakfast Club. “In Sixteen Candles, I figured it would only be gratuitous to show Samantha and Jake in anything more than a kiss,” he said. “The kiss is the most beautiful moment. I was really amused when someone once called me a ‘purveyor of horny sex comedies.’ He listed The Breakfast Club and Mr. Mom in parentheses. I thought, ‘What kind of sex?’ Yes, in Mr. Mom there’s a baby in a bathtub and you see its bare butt.”

10. MR. MOM WAS MADE INTO A TV MOVIE AFTER ALL.

In the beginning, producers wanted Mr. Mom to be a TV movie, not a feature film. But a year after the film came out in theaters, ABC produced a TV movie called Mr. Mom, with the same characters and premise. Barry Van Dyke played Jack and Rebecca York played Caroline. A People magazine review of the movie stated: “They and their three kids are immediately likable … But it goes downhill from there as the script lobotomizes all its characters. Here’s a textbook case in how TV takes a cute idea—and a script that does have some good lines—and leeches the wit out of it.”

Though he made his living as a writer, Ernest Hemingway was just as famous for his lust for adventure. Whether he was running with the bulls in Pamplona, fishing for marlin in Bimini, throwing back rum cocktails in Havana, or hanging out with his six-toed cats in Key West, the Nobel and Pulitzer Prize-winning author never did anything halfway. And he used his adventures as fodder for the unparalleled collection of novels, short stories, and nonfiction books he left behind, The Sun Also Rises, A Farewell to Arms, Death in the Afternoon, For Whom the Bell Tolls, and The Old Man and the Sea among them.

On what would be his 119th birthday—he was born in Oak Park, Illinois on July 21, 1899—here are 20 memorable quotes that offer a keen perspective into Hemingway’s way of life.

"I like to listen. I have learned a great deal from listening carefully. Most people never listen."

ON TRUST

"The best way to find out if you can trust somebody is to trust them."

ON DECIDING WHAT TO WRITE ABOUT

"Happiness in intelligent people is the rarest thing I know."

ON TRUTH

"There's no one thing that is true. They're all true."

ON THE DOWNSIDE OF PEOPLE

"The only thing that could spoil a day was people. People were always the limiters of happiness, except for the very few that were as good as spring itself."

ON SUFFERING FOR YOUR ART

"There is nothing to writing. All you do is sit down at a typewriter and bleed."

ON TAKING ACTION

"Never mistake motion for action."

ON GETTING WORDS OUT

"I wake up in the morning and my mind starts making sentences, and I have to get rid of them fast—talk them or write them down."

ON KEEPING PROMISES

"Always do sober what you said you'd do drunk. That will teach you to keep your mouth shut."

ON GOOD VS. EVIL

"About morals, I know only that what is moral is what you feel good after and what is immoral is what you feel bad after."

ON REACHING FOR THE UNATTAINABLE

"For a true writer, each book should be a new beginning where he tries again for something that is beyond attainment. He should always try for something that has never been done or that others have tried and failed. Then sometimes, with great luck, he will succeed."

ON HAPPY ENDINGS

"There is no lonelier man in death, except the suicide, than that man who has lived many years with a good wife and then outlived her. If two people love each other there can be no happy end to it."
