The act of high-fiving a friend in celebration may seem like it’s been around forever, but in fact, the gesture originated even more recently than cellphones or email. Lacking any earlier reputable reports, the most widely accepted origin story goes as follows: The high-five was first used during a baseball game between the Los Angeles Dodgers and Houston Astros on October 2, 1977. After hitting his 30th home run of the season, left fielder Dusty Baker was greeted by his teammate Glenn Burke, who excitedly offered a raised hand to celebrate, which Baker then slapped in return. Burke then hit a home run of his own, and the pair repeated the motion. 

The players celebrated another homer hit three days later with their new gesture, and that moment was photographed by the Los Angeles Times, which ran the image on the front page of the October 6 edition with the caption “GIVE HIM A HAND.” It wasn’t until 1980 that the term “high-five” was definitively coined and began appearing in print, with its first such appearance in a March 25 Boston Globe article, according to the Oxford English Dictionary.

The thumbs-up is considered offensive in certain cultures.

Despite its positive connotation in Western culture, the thumbs-up gesture is akin to giving the middle finger in other parts of the world. It remains taboo in parts of West Africa, the Middle East, Australia, Greece, and elsewhere, though younger generations may not consider it as offensive.

Another oft-cited report attributes the creation of the high-five to the 1978-1979 University of Louisville men’s basketball team. During practice, Wiley Brown offered his teammate Derek Smith a low-five — a knee-level gesture that was commonly used by African Americans as a symbol of unity. At that moment, as reported in The Week, Smith responded, “No. Up high,” thus giving literal rise to a new gesture. This was cited as the origin of the high-five in a New York Times article on September 1, 1980. However, this event postdates the Baker-Burke story, which makes the NYT’s claim suspect (assuming the reported timelines are indeed accurate).

Handshakes date back to ancient Mesopotamia.

Handshakes were used by people in ancient Mesopotamia no later than the ninth century BCE. One of the earliest examples is a stone relief from that era depicting the kings of Babylon and Assyria shaking hands to commemorate a pact. The gesture was later mentioned several times by Homer in the “Iliad” and “Odyssey” as a way to convey trust between two parties.

Shaking hands as a greeting was popularized, in part, by Quakers in the 17th century. Many Quakers weren’t particularly fond of greeting people with traditional bows or curtsies, as those gestures reinforced an unequal, hierarchical structure. Instead, they began using handshakes as a sign of equal respect.

The Appalachian Mountains aren’t the world’s largest mountains. And though they stretch from Canada to Alabama, they aren’t even the world’s longest (that honor goes to the mid-ocean ridge, a chain 40,389 miles long). However, the Appalachian chain does stand among the world’s oldest mountains, with some of its rocks dating back 1.2 billion years — a milestone that makes these peaks older than the Atlantic Ocean. 

There are mountains under the ocean.

Earth’s mountains don’t just reach into the sky; they also take up much of the ocean floor. These underwater mountains — aka seamounts — are created by deep-sea volcanoes, and scientists estimate they account for more than 11 million square miles of the planet’s surface.

The oldest parts of the Appalachian Mountains began to rise when our planet looked much different. At the time of their creation, North America was still attached to Europe and most of Asia, making up the supercontinent Laurasia. However, a collision between Laurasia and Gondwana — the massive continental fusion that included Africa, India, South America, Australia, and Antarctica — would eventually create Pangaea, and the first Appalachian peaks along with it. As Pangaea formed around 320 million years ago, the earliest Appalachian mountains began to grow, reaching far higher into the sky than they do today; initially, the southern subrange we call the Blue Ridge Mountains had the largest summits in the world. However, Pangaea eventually broke apart, leaving a rift that would become the Atlantic Ocean about 150 million years ago, as the continents separated. 

Today, around 3 million people hike through the Appalachian Mountains along the Appalachian Trail, a feat that wouldn’t at all be possible had the mountain range remained as high as the Himalayas. Thankfully for backpackers, millions of years of erosion have brought the still-stunning mountain chain to a more trekkable level, averaging a more manageable 3,000 feet above sea level.

Earth hasn’t always had oceans.

Some scientists believe Earth’s earliest form didn’t have an ocean for its first billion years. Initially, Earth’s temperatures were too hot, and while water molecules did exist on the planet, above-boiling temps kept them from condensing into a liquid. As the planet slowly began to cool, water no longer evaporated, and oceans had a chance to form; researchers theorize the first major body of water began appearing around 3.8 billion years ago. Over millions of years, the ocean gradually collected more water, and filled in the planet’s basins and hollows. Today the life-sustaining liquid covers more than 70% of our world’s surface.

Spend enough time at Disneyland and you’ll see them. Maybe you’ll spot one snoozing in the bushes near the Jungle Cruise or observing you warily as you ride the tram, but one thing is certain: However many cats you see, there are more out of sight. About 200 feral cats roam the Happiest Place on Earth, where they earn their keep by helping to control the rodent population. The felines were first seen not long after Disneyland opened in 1955, when they took up residence in Sleeping Beauty Castle, and it soon became evident that keeping them around had more advantages than trying to escort them off the premises.

Disneyland was almost built somewhere else.

Though the park ended up being built in Anaheim, Walt Disney originally proposed constructing it just down the street from Walt Disney Studios in Burbank. Anaheim was chosen in part because there was more land available to accommodate Disney’s expanding vision.

The mutually beneficial alliance even includes permanent feeding stations for the cats, as well as spaying or neutering and vaccinations. Though not official cast members, these adept hunters — who mostly come out at night — have earned a devoted following of their own. There are websites, Instagram feeds, and YouTube videos devoted to them. They’re not quite as popular as the actual rides at Disneyland, of course, but for cat lovers, they’re an attraction all their own.

Our friends in ancient Rome indulged in a lot of activities that we would find unseemly today — including and especially gladiators fighting to the death — but they drew the line at eating butter. To do so was considered barbaric, with Pliny the Elder going so far as to call butter “the choicest food among barbarian tribes.” In addition to a general disdain for drinking too much milk, Romans took issue with butter specifically because they used it for treating burns and thus thought of it as a medicinal salve, not a food. 

Rome was founded by twin brothers Romulus and Remus.

It’s a great story, but it’s just that — a story. The mythological siblings who were nursed by a she-wolf after being sent down the River Tiber in a basket have long been a key part of Roman mythology.

They weren’t alone in their contempt. The Greeks also considered the dairy product uncivilized, and “butter eater” was among the most cutting insults of the day. In both cases, this can be partly explained by climate — butter didn’t keep as well in warm southern climates as it did in northern Europe, where groups such as the Celts gloried in their butter. Instead, the Greeks and Romans relied on olive oil, which served a similar purpose. To be fair, though, Romans considered anyone who lived beyond the Empire’s borders (read: most of the world) to be barbarians, so butter eaters were in good company.

Nero didn’t actually fiddle while Rome burned.

It would have been impossible for him to do so, as the fiddle didn’t exist yet. That’s not to say that Nero was a good emperor (or person), however. In addition to murdering his mother, first wife, and possibly his second wife as well, Nero may have even started the infamous fire that burned for six days in 64 CE and destroyed 70% of the city so that he could expand his Golden Palace and nearby gardens. (Or at least, that’s what some of the populace and some ancient writers suspected.) For all that, Rome’s fifth emperor wasn’t entirely reviled during his time — and it’s been suggested that his cruelty was at least somewhat exaggerated by later historians who were looking to smear his dynastic line, known as the Julio-Claudians. And he was a gifted musician who played the cithara, an ancient stringed instrument similar to a lyre — just not the fiddle.

Like many classic Hollywood stars, Joan Crawford was known by a stage name rather than her real name. Born Lucille Fay LeSueur, the future Oscar winner made her silver-screen debut in 1925’s Lady of the Night under her birth name. Metro-Goldwyn-Mayer, which had signed her to a $75-a-week contract, saw potential in the starlet but feared her name would be a hindrance; Pete Smith, the head of publicity at MGM, thought her surname sounded too much like the word “sewer.” 

So the upper brass at MGM landed on a novel solution: a contest run in the fan magazine Movie Weekly, which offered between $50 and $500 for coming up with a new name for “a beautiful young screen actress.” The perfect name, according to MGM, “must be moderately short and euphonious. It must not imitate the name of some already established artiste. It must be easy to spell, pronounce, and remember. It must be impressive and suitable to the bearer’s type.”

No one’s sure when Joan Crawford was born.

Ready to reveal?

Oops, incorrect!

It's a fact

Though biographers know her birthday was March 23, the year has been listed as 1904, 1905, 1906, and 1908 by various sources.

The winner, as fate would have it, wasn’t Joan Crawford; it was Joan Arden, which was already the name of an extra who threatened to sue MGM. And so the second-place winner was chosen instead, not that the new Joan Crawford was happy about it — she initially hated the name before making the most of it.

Crawford accepted her Oscar from bed.

After a string of hits in the late 1920s and early ’30s, Crawford’s luck so reversed itself that she was deemed “box-office poison” in TIME magazine by the end of the decade. Her comeback wasn’t fully solidified until she took the title role in 1945’s Mildred Pierce, which resulted in her sole Academy Award — not that she was expecting to win.

Believing Ingrid Bergman would take home the Oscar for The Bells of St. Mary’s, Crawford was disinclined to attend any ceremony where she wouldn’t be victorious and opted to feign illness. Upon learning she’d won, however, she put on her makeup, invited members of the press to her bedroom, and accepted the statuette from the comfort of her own bed.

The world’s largest coffeehouse chain, Starbucks, almost had a very different name. According to a 2008 Seattle Times interview with the company’s co-founder Gordon Bowker, the famous java chain was once “desperately close” to being called “Cargo House,” a name meant to tie the first store (in Seattle’s Pike Place Market) to the idea of beans coming from far away. Anxious for another, more pleasing moniker, a brand consultant working with Bowker mentioned that words starting with “st” felt especially strong. Bowker ran with the idea, listing every “st” word he could think of. The breakthrough moment occurred after the consultant brought out some old maps of the Cascade mountains and Mount Rainier — both close to the company’s hometown of Seattle — and Bowker stumbled across an old mining town named “Starbo.” The name lit up a literary reference embedded in his mind: Starbuck. 

The musician Moby is related to Herman Melville, the author of “Moby-Dick.”

Ready to reveal?

Oops, incorrect!

It's a fact

Born Richard Melville Hall but nicknamed “Moby” as a baby, the musician says he’s the great-great-great-nephew of author Herman Melville. In 2016, Moby followed in his ancestor’s publishing footsteps and came out with a memoir titled “Porcelain.” He has since released a second memoir.

The name comes from Herman Melville’s 1851 masterpiece Moby-Dick; or, The Whale. In the novel, Starbuck is a Quaker and trusty first mate of Captain Ahab, and serves as the voice of reason aboard the whaling ship Pequod (another name the Starbucks co-founders considered). Melville himself likely got the name Starbuck from a real whaling family that lived on the Massachusetts island of Nantucket in the late 18th and early 19th centuries. Bowker readily admits that the character has nothing to do with coffee, but the moniker stuck, and the company doubled down on the nautical theme by introducing a mythological siren, likely influenced by a seventh-century Italian mosaic, as its now-famous green-and-white logo.

Coffee beans are not actually beans.

Two types of flowering shrubs from the family Rubiaceae, Coffea robusta and Coffea arabica, make up most of the coffee consumed in the world. These plants produce a sweet, reddish-yellow cherry-like fruit, and its seeds or pits — when roasted from light to dark — make the coffee beverage we know and love today. However, calling these seeds “beans” is a misnomer, since a “bean” technically refers to an edible seed from the plant family Fabaceae (also called Leguminosae), which includes foods such as soybeans, peas, chickpeas, and peanuts. Coffee seeds look much like a typical bean, but from a strict botanical perspective, they’re not. In fact, since coffee cherries are fruits, you might argue that your usual cup of joe has more in common with a smoothie than any sort of legume-heavy delicacy.

The word “hippopotamus” means “river horse” in Greek, which makes sense given the amount of time — about 16 hours a day — these massive creatures spend in the water. But as it turns out, hippos can’t actually swim or even float. Their dense bones and heavy bodies cause them to sink, and their short legs and broad structure aren’t built for moving through water as easily as other aquatic mammals. 

What they can do, thanks to that density, is stand sturdily on a waterbed’s floor and walk or bounce along the ground. With their eyes and nostrils located high on their heads, they can still see and breathe while almost completely submerged.

Dolphins can recognize themselves in the mirror.

Ready to reveal?

Oops, incorrect!

It's a fact

Dolphins recognize their own reflection as early as 7 months old, showing self awareness even earlier than human babies.

Although they prefer the shallower parts of lakes, rivers, and swamps — typically around 6 feet deep — they’ve been observed in waters as deep as 40 feet, which they can propel themselves above by leaping like porpoises off the bottom. Even when they sleep, they can hold their breath for only about five minutes before an automatic reflex ensures they rise to the surface for air so they can rest without drowning.

The water isn’t just a playground for these creatures — it’s vital to their survival. Staying submerged helps keep their sensitive skin cool and hydrated under the hot African sun. It isn’t until dusk that they emerge and spend the next eight hours or so on land, grazing on grasses, before returning to their aquatic refuge when the sun reappears.

The kid who sang “I Want a Hippopotamus for Christmas” actually got one.

In 1953, 10-year-old Oklahoma child Gayla Peevey recorded the quirky holiday tune “I Want a Hippopotamus for Christmas.” After the song became a hit, an Oklahoma City zoo and a local newspaper launched a statewide funding drive, encouraging people to chip in so they could give Peevey the very thing she sang about.

Donations poured in, and by Christmas, a baby hippopotamus named Mathilda was sent to Oklahoma City. Peevey gave the hippo to Oklahoma’s Lincoln Park Zoo, making Mathilda  the zoo’s first hippo, and appeared alongside zookeepers and the media to help welcome Mathilda to her new home.

With apologies to anyone who already found The Birds terrifying while under the impression that it was wholly fictional: Alfred Hitchcock’s avian thriller was partly based on a true story. Said event took place on California’s Monterey Bay in August 1961, when “thousands of crazed seabirds” called sooty shearwaters were seen regurgitating anchovies and flying into objects before dying on the streets. The Master of Suspense happened to live in the area and called the Santa Cruz Sentinel — which had reported on the strange goings-on in its August 18 edition — for more information. Long after his movie was released two years later, the bizarre event remained shrouded in mystery: What would inspire birds to act this way, and were they as malicious as they seemed in Hitchcock’s movie?

“The Birds” features a cameo by Hitchcock.

Ready to reveal?

Oops, incorrect!

As he did in more than 30 of his other films, Hitchcock briefly appears in “The Birds.” The cameo comes just two minutes in, when the director is seen leaving a pet shop with two white terriers (his own pups Geoffrey and Stanley) as Tippi Hedren’s character enters.

The truth ended up being both straightforward and a little sad. The scientific consensus is now that the birds were poisoned by toxic algae found in a type of plankton called Pseudo-nitzschia. The birds weren’t attacking anyone; they were disoriented and barely in control of their actions. That explanation is absent from Hitchcock’s thriller, which also drew inspiration from Daphne du Maurier’s short story of the same name. (Hitchcock’s Rebecca was also a du Maurier adaptation.) A resounding success, The Birds is widely considered one of Hitchcock’s greatest works, alongside Psycho, Vertigo, Rear Window, and North by Northwest.

One of Hitchcock’s earliest films is lost.

A full 86% of American-made films from the silent era (1912-1929) are considered lost, meaning they don’t survive as complete works in their original form. Among them is one by the Master of Suspense himself: 1926’s The Mountain Eagle, the second feature he ever directed. Though some production stills remain, all prints of the Kentucky-set melodrama have been lost. Hitchcock completists have spent the better part of a century bemoaning this, but he wasn’t especially bothered by it — he once referred to it as “a very bad movie.” Even so, the British Film Institute has long included The Mountain Eagle on its 10 Most Wanted list of lost films.

New parents are responsible for a lot: feeding a hungry baby, keeping track of naps while not sleeping much themselves, and in one instance, saving years of their co-workers’ hard work. At least that was the case for Galyn Susman, the Pixar technical director credited with bringing Toy Story 2 back from the depths of deletion in 1998. Susman, a new parent out of office on maternity leave, was notified that 90% of the film had been accidentally deleted thanks to a software snafu; what’s worse, the studio’s on-site backups had failed. Miraculously, Susman had copies of the film on her laptop, which she had been working on during her leave. The laptop was wrapped in blankets and gingerly carted back to the Pixar studio, where the files ended up saving the production.

Disney’s early cartoons are film industry icons, but they weren’t the first of their kind. Argentinian illustrator Quirino Cristiani completed “El Apóstol,” the first feature-length animated film, in 1917 — 20 years before “Snow White”— but lost the political satire to a fire.

Susman’s copy of Toy Story 2 wasn’t the one that ended up on the big screen, but for good reason. The first Toy Story film debuted in 1995 and was a box-office success, drawing three Oscar nominations and winning the Academy’s Special Achievement Award as the first feature film created entirely with computer animation. But when it came to Toy Story 2, Disney and Pixar planned for the sequel to skip theaters altogether, opting for a direct-to-video production. During the animation process, Pixar creatives successfully advocated for a full theatrical release; however, that meant reworking the entire film in less than nine months before its scheduled November 1999 release date. The tight turnaround paid off: Toy Story 2 became the third-highest-grossing film that year, and today remains a beloved chapter in the Toy Story franchise.

Toy companies initially thought the “Toy Story” films would flop.

A scene in Toy Story 2 pokes fun at a real-life gaffe made by toy companies: failing to see that the animated franchise would be a major moneymaker. Disney approached toy manufacturers nearly a year before the first film’s release, hoping to produce a line of character action figures and dolls. But two big-name companies — Hasbro and Mattel — turned down the licensing opportunity, worried the computer-animated film would be a flop, and that there wasn’t even enough time to create the toys. A small Canadian toy maker landed the gig, but couldn’t keep up with orders. By Christmas of 1996, the film was so popular and demand for a limited stock of Toy Story figurines was so high that desperate parents paid more than four times the retail price from unscrupulous sellers. The holiday shopping fallout has since been immortalized in the first Toy Story sequel, in which Barbie cheerfully relays the tale of the toy shortage — a situation Disney made sure not to repeat with each subsequent movie release.

The first dinosaur fossil was discovered in 1677 — not that the man who came upon it realized the magnitude of his find. The English naturalist Robert Plot thought that his discovery had belonged to a giant human, and it wasn’t until 1824 that the geologist William Buckland identified the bone for what it was. It took an additional 18 years for Sir Richard Owen, the most famed paleontologist of his era, to coin the term “dinosauria” — deinos meaning “terrible” or “fearfully great” in Greek, and sauros meaning “lizard.” True lizards and dinosaurs diverged from one another 270 million years ago, but the name stuck nevertheless. 

Land-dwelling dinosaurs and humans lived on Earth at the same time.

Despite what “The Flintstones” led us to believe, humans never shared the planet with velociraptors, triceratops, or other non-avian dinosaurs. Early human ancestors first appeared in Africa some 6 million years ago, or 60 million years after the dinosaurs’ reign ended.

Suffice to say that the schoolteacher who called a young Owen “impudent” would have been surprised by his lasting scientific contributions, which also include describing many new species and founding London’s Natural History Museum. Owen later went on to feud with none other than Charles Darwin over their respective views on evolution. Owen developed his own influential theory of how animals developed, and disagreed with how Darwin interpreted it in On the Origin of Species — as well as with Darwin’s entire concept of natural selection. As a result, Owen’s scientific reputation has suffered, but we can still thank him for every 7-year-old’s favorite word.

Dinosaurs aren’t considered extinct.

Not fully, anyway. While the vast majority of our prehistoric friends did indeed die out after an asteroid likely hit the planet about 65 million years ago, some persisted — and today we call them birds. There are 10,000 species of dinosaurs alive today, none of which is as fearsome as a Tyrannosaurus rex but all of whom are marvels of evolution. The ancestors of modern birds survived while other dinosaurs died out in part by shrinking their size and exploiting a different, less-competitive ecological niche than their bulkier, land-dwelling relatives. Between the dinosaurs of old and the birds of today was the Archaeopteryx, a “transitional fossil” with both avian and reptilian features that lived some 150 million years ago.
