1. The Real World: Mental Hospital Edition

This is the true story of three schizophrenics, who all believed they were Jesus Christ. It wasn’t long before they stopped being polite and started getting real crazy. In 1959, social psychologist Milton Rokeach wanted to test the strength of self-delusion. So, he gathered three patients, all of whom identified themselves as Jesus Christ, and made them live together in the same mental hospital in Michigan for two years.

Rokeach hoped the Christs would give up their delusional identities after confronting others who claimed to be the same person. But that’s not what happened. At first, the three men quarreled constantly over who was holier. According to Rokeach, one Christ yelled, “You oughta worship me!” To which another responded, “I will not worship you! You’re a creature! You better live your own life and wake up to the facts!”

Unable to turn the other cheek, the three Christs often argued until punches were thrown. Eventually, however, they each explained away their conflicting identities. One believed, correctly, that the other two were mental patients. Another rationalized the presence of his companions by claiming that they were dead and being operated by machines.

But the behavior of the schizophrenics isn’t even the most bizarre part. Far stranger was the way Rokeach tried to manipulate his subjects.

As part of the experiment, the psychologist wanted to see just how entrenched each man’s delusions were. For example, one of the Christs, Leon, believed he was married to a person he called Madame Yeti Woman, a 7-ft.-tall, 200-lb. descendant of an Indian and a jerboa rat. So, Rokeach wrote love letters to Leon from Madame Yeti Woman. They contained instructions, requesting that Leon sing “Onward Christian Soldiers” during group meetings and smoke a certain brand of cigarettes. Leon was so touched by the attention from his make-believe wife that he broke into tears upon receiving the letters. But when the Yeti Woman asked him to change his name, Leon felt as though his identity was being challenged. He was on the verge of divorcing his fantasy spouse when Rokeach finally dropped that part of the experiment.

At the end of their two-year stay, each man still believed he was the one and only son of God. In fact, Rokeach concluded that their Jesus identities may have become more embedded after being confronted with other Christs. Twenty years later, he renounced his methods, writing, “I really had no right, even in the name of science, to play God and interfere around the clock with their daily lives.”

2. Raging Bull

In 1963, Dr. Jose Delgado stepped into a bullring in Cordova, Spain, with a 550-lb. charging bull named Lucero. The Yale University neurophysiologist was no bullfighter, but he had a plan: to control the bull’s mind.

Delgado was among a small group of researchers developing a new type of electroshock therapy. Here’s how it worked: First, the researchers would implant tiny wires and electrodes into the skull. Then, they’d send electrical surges to different parts of the brain, sparking emotions and triggering movements in the body. The goal was to change the patient’s mental state, perking up the depressed and calming the agitated. But Delgado took this science to a new level when he developed the “stimoceiver.” The chip, which was about the size of a quarter, could be inserted inside a patient’s head and operated by remote control. Delgado envisioned the technology eventually leading to a “psychocivilized society,” in which everyone could temper their self-destructive tendencies at the press of a button.

For several years, Delgado experimented on monkeys and cats, making them yawn, fight, play, mate, and sleep—all by remote control. He was particularly interested in managing anger. In one experiment, he implanted a stimoceiver into a hostile monkey. Delgado gave the remote control to the monkey’s cage mate, who quickly figured out that pressing the button calmed down his hotheaded friend.

Delgado’s next challenge was to experiment with bulls in Spain. He began by implanting stimoceivers into several bulls and testing the equipment by making them lift their legs, turn their heads, walk in circles, and moo 100 times in a row. Then came the moment of truth. In 1965, Delgado entered the ring with a fighting bull named Lucero—a ferocious animal famous for his temper. When Lucero barreled towards him, Delgado tapped his remote control and brought the animal to a screeching halt. He tapped his remote control again, and the bull started wandering in circles.

The demonstration was hailed as a success on the front page of The New York Times, but some neuroscientists were skeptical. They suggested that, rather than quelling Lucero’s aggression, Delgado had simply confused the bull by shocking his brain and prompting him to give up his attack. Meanwhile, total strangers began accusing Delgado of secretly implanting stimoceivers into their brains and controlling their thoughts. As public fear of mind-control technology increased during the 1970s, Delgado decided to return to Spain and conduct less-controversial research. But his work on electrical brain stimulation was groundbreaking. It paved the way for present-day neural implants, which help patients manage conditions ranging from Parkinson’s disease and epilepsy to depression and chronic pain.

3. Alone in the Dark

For some people, solitary confinement is a punishment; for others, it’s a pathway to scientific discovery. In the 1960s, at the peak of the Space Race, scientists were curious how humans would handle traveling in space and living in fallout shelters. Could people cope with extreme isolation in a confined space? Without the Sun, what would our sleep cycles be like? Michel Siffre, a 23-year-old French geologist, decided to answer these Cold War questions by conducting an experiment on himself. For two months in 1962, Siffre lived in total isolation, buried 375 feet inside a subterranean glacier in the French-Italian Maritime Alps, with no clocks or daylight to mark time.

Inside the cave, temperatures were below freezing, with 98 percent humidity. Constantly cold and wet, Siffre suffered from hypothermia, as massive chunks of ice regularly crashed down around his tent. But during his 63 days underground, he only dabbled in madness once. One day, Siffre started singing at the top of his lungs and dancing the twist in his black silk tights. Other than that, he behaved relatively normally.

When Siffre emerged on September 14, he thought it was August 20. His mind had lost track of time, but, oddly enough, his body had not. While in the cave, Siffre telephoned his research assistants every time he woke up, ate, and went to sleep. As it turns out, he’d unintentionally kept regular cycles of sleeping and waking. An average day for Siffre lasted a little more than 24 hours. Humans beings, Siffre discovered, have internal clocks.

The experiment’s success made Siffre eager to conduct more research. Ten years later, he descended into a cave near Del Rio, Texas, for a six-month, NASA-sponsored experiment. Compared to his previous isolation experience, the cave in Texas was warm and luxurious. His biggest source of discomfort were the electrodes attached to his head, which were meant to monitor his heart, brain, and muscle activity. But he got used to them, and the first two months in the cave were easy for Siffre. He ran experiments, listened to records, explored the cavern, and caught up on his Plato.

On day 79, however, his sanity started to crack. He became extremely depressed, especially after his record player broke and mildew began ruining his magazines, books, and scientific equipment. Soon, he was pondering suicide. For a while, he found solace in the companionship of a mouse that occasionally rummaged through his supplies. But when Siffre tried to trap the mouse with a casserole dish to make it his pet, he accidentally crushed and killed it. He wrote in his journal, “Desolation overwhelms me.”

Just when the experiment was nearing its end, a lightning storm sent a shock of electricity through the electrodes on his head. Although the pain was excruciating, depression had so dulled his mind that he was shocked three more times before he thought to disconnect the wires.

Yet again, the Texas cave experiment yielded interesting results. For the first month, Siffre had fallen into regular sleep-wake cycles that were slightly longer than 24 hours. But after that, his cycles began varying randomly, ranging from 18 to 52 hours. It was an important finding that fueled interest in ways to induce longer sleep-wake cycles in humans—something that could potentially benefit soldiers, submariners, and astronauts.

4. For the Love of Dolphins

Perhaps the most troubling experiment in recent history is the dolphin-intelligence study conducted by neuroscientist John C. Lilly in 1958. While working at the Communication Research Institute, a state-of-the-art laboratory in the Virgin Islands, Lilly wanted to find out if dolphins could talk to people. At the time, the dominant theory of human language development posited that children learn to talk through constant, close contact with their mothers. So, Lilly tried to apply the same idea to dolphins.

For 10 weeks in 1965, Lilly’s young, female research associate, Margaret Howe, lived with a dolphin named Peter. The two shared a partially flooded, two-room house. The water was just shallow enough for Margaret to wade through the rooms and just deep enough for Peter to swim. Margaret and Peter were constantly interacting with each other, eating, sleeping, working, and playing together. Margaret slept on a bed soaked in saltwater and worked on a floating desk, so that her dolphin roommate could interrupt her whenever he wanted. She also spent hours playing ball with Peter, encouraging his more “humanoid” noises and trying to teach him simple words.

As time passed, it became clear that Peter didn’t want a mom; he wanted a girlfriend. The dolphin became uninterested in his lessons, and he started wooing Margaret by nibbling at her feet and legs. When his advances weren’t reciprocated, Peter got violent. He started using his nose and flippers to hit Margaret’s shins, which quickly became bruised. For a while, she wore rubber boots and carried a broom to fight off Peter’s advances. When that didn’t work, she started sending him out for conjugal visits with other dolphins. But the research team grew worried that if Peter spent too much time with his kind, he’d forget what he’d learned about being human.

Before long, Peter was back in the house with Margaret, still attempting to woo her. But this time, he changed his tactics. Instead of biting his lady friend, he started courting her by gently rubbing his teeth up and down her leg and showing off his genitals. Shockingly, this final strategy worked, and Margaret began rubbing the dolphin’s erection. Unsurprisingly, he became a lot more cooperative with his language lessons.

Discovering that a human could satisfy a dolphin’s sexual needs was the experiment’s biggest interspecies breakthrough. Dr. Lilly still believed that dolphins could learn to talk if given enough time, and he hoped to conduct a year-long study with Margaret and another dolphin. When the plans turned out to be too expensive, Lilly tried to get the dolphins to talk another way—by giving them LSD. And although Lilly reported that they all had “very good trips,” the scientist’s reputation in the academic community deteriorated. Before long, he’d lost federal funding for his research.

5 Fast Facts About Billy the Kid

On September 23, 1875, Billy the Kid was arrested for the first time. Whether you think he was a misunderstood old West hero or nothing but a cold-blooded killer, it's impossible to argue that he was an interesting man. Here are five facts to prove it.

1. HIS "REAL" NAME IS A TOPIC OF DEBATE.

Billy the Kid's real name? Henry McCarty. Or maybe William Bonney. Or Henry Antrim. Take your pick. He was born Henry McCarty, but there's some speculation that his dad may have been a man named William Bonney. Billy the Kid started using his name at some point in 1877. Antrim was his step-father's last name; he went by that for some time as well.

2. HE WORKED AT A CHEESE FACTORY.

Billy the Kid wasn't always engaging in illegal activities and shooting people; he once worked at a cheese factory—at least he did according to Charlie Bowdre, a man who would later be in Billy's posse, and was part owner of the cheese factory. Bowdre's descendants have said this is where the two of them met, although his employ was short.

3. HIS LEGEND MAY BE A BIT OF AN EXAGGERATION.

You may have heard the legend that Billy killed 21 people—one for each year of his rather short life. It's just that: legend. We only have evidence that Billy killed four people, two of them prison guards. He may have "participated" in the deaths of up to five more people.

4. CONTRARY TO POPULAR BELIEF, HE PROBABLY WASN'T LEFT-HANDED.

The reason this notion became widespread is because of the famous ferrotype of him that shows him wearing a gun belt with the holster on the left side. It was later discovered that the image has been reproduced incorrectly and flipped to show the mirror image of what really was. The picture actually shows Billy with his gun on his right hip.

5. SOME PEOPLE BELIEVE HE FAKED HIS OWN DEATH.

Many people—including some claiming to be Billy himself—have said Billy didn't actually die on July 14, 1881 in Fort Sumner, New Mexico, which is the official story. Many claim that Sheriff Pat Garrett didn't kill Billy, but actually helped him fake his death and happily ride off into the sunset. No evidence has ever been found to support this, though.

Men claiming to be Billy include Ollie "Brushy Bill" Roberts and a man named John Miller. Brushy Bill started claiming to be Billy the Kid in 1949, and knew quite a few intimate details about Billy's life and the Lincoln Country War. But there were several gunfights he was pretty clueless about, and photo comparisons using sophisticated computer programs show the men to have completely different bone structure and other features.

As for John Miller, his claims were basically put to rest in 2005 when his bones were disinterred and DNA samples were taken. They were compared to a blood sample thought to be Billy the Kid's and there was no match.

10 Intriguing Friends Fan Theories

Friends is a show about twentysomethings navigating life, love, and work in New York City. Ot at least that’s one theory about the beloved sitcom, which debuted on this day in 1994. Here’s another: Friends is a glimpse inside a mental ward, where six disturbed patients are working through their personality disorders. In the 14 years since it went off the air, Friends has inspired a ton of wild fan theories on Reddit and Twitter. Here are a few of the strangest (and be careful: Mr. Heckles’s murderer is still at large).

1. RACHEL DREAMED THE WHOLE THING.

In the summer of 2017, this photo of the Friends season four DVD box ignited a fan frenzy. The image on the box shows the titular pals snoozing side by side. Ross, Phoebe, Monica, Chandler, and Joey all have their eyes shut, but Rachel—resting right in the middle—is wide awake and looking directly at the camera. Why is she the only one with her eyes open? Some fans suggested Rachel was plotting something sinister, or secretly very “woke.” But plenty more insisted it was proof the whole show was Rachel’s dream. According to one Twitter fan, Rachel fell into an anxiety-fueled dream the night before her wedding to Barry and imagined her own group of hip New York friends to cope with her frustration and dread. Except she woke up to reality the next morning, as shown on the DVD cover, where she’s surrounded by her dream friends.

2. PHOEBE HALLUCINATED THE SHOW.

Another popular theory suggests the show was all in Phoebe’s head—only this take is much darker. The basic premise is that Phoebe never got off the streets. She was a lonely, homeless woman with a meth addiction who peered into the window of Central Perk one day. She noticed five friends laughing over coffee, and imagined herself as part of the gang. In this fantasy, her pals didn’t always get her weird sense of humor, but they loved her anyway. In reality, the twentysomethings in the window were wondering why that “crazy lady” was staring at them. This theory gained so much traction that a journalist asked Friends co-creator Marta Kauffman about it at a television festival. She quickly threw water on the whole thing. “That’s the saddest thing I’ve ever heard,” Kauffman replied. “That’s a terrible theory. That’s insane. Someone needs a life, that’s all I’m saying."

3. IT WAS ONE LONG PROMO FOR STARBUCKS.

According to one manic Facebook rant, Friends was not a sitcom at all. It was actually a 10-year marketing ploy, designed to make Starbucks the new go-to destination for young people. Why else do the characters spend so much time in a coffee shop? True, the shop is not called Starbucks, but the subliminal evidence lies in Rachel’s last name (Green, like the Starbucks company color) and hair (styled like the mermaid in the Starbucks logo). Then there’s Ross and Monica’s last name, Geller, which is close to the German word gellen. It means “to yell,” just like the Starbucks baristas calling out customer names. The case only gets flimsier from there, but if you really want to read about how Chandler and Moby Dick are connected, you can dive down the rabbit hole here.

4. ROSS LOST CUSTODY OF BEN BECAUSE HE WAS A BAD DAD.

Ross’s son Ben arrives in the very first season of Friends, in the aptly titled episode “The One with the Birth.” He’s a constant character for several seasons, but as the show goes on, Ross seems to spend less and less time with his kid. Ben disappears after the eighth season, and never meets his half-sister Emma onscreen. There’s one explanation for this dropoff: Ross lost custody of his son due to increasingly disturbing behavior.

The blog What Would Bale Do lays out a bunch of examples: Ross sleeps with his students, tries to hook up with his cousin, and asks a self-defense instructor for help scaring his female friends. He’s also generally pretty jealous and possessive. According to this theory, Ross’s ex-wife Carol hit a breaking point and took full custody of their son, which is why Ben stops coming around his dad’s apartment in the later seasons.

5. MR. HECKLES WAS MURDERED.

Rachel and Monica’s mean old neighbor dies of natural causes in season two—or at least that’s what they want you to think. By one Redditor’s account, Mr. Heckles was killed in cold blood. Moments before he dies, Mr. Heckles shows up at Monica and Rachel’s door, complaining that their noise is disturbing his birds. (He does not have birds.) Monica says they’ll try to keep it down and as Mr. Heckles leaves, he says he’s going to rejoin his “dinner party.” Minutes later, he’s dead. Ergo, his dinner party guest killed him. Of course, the likelier explanation is that Mr. Heckles was a crazy old man who wasn’t even having a dinner party. But where’s the fun in that?

6. THERE’S A REASON THEY ALWAYS GOT THAT TABLE AT CENTRAL PERK.

How did the gang manage to snag the coveted center couch at Central Perk every single time? Simple: Gunther reserved it for them. It was all part of his ongoing campaign to win Rachel’s affections, and it explains why the group never had to fight for seating space. Well, except that one time.

7. THERE’S A PARKS & RECREATION CROSSOVER.

In “The One With All the Candy,” Rachel insists she doesn’t sleep with guys on the first date, only for her friends to immediately call her out. Monica rattles off three names: Matt Wire, Mark Lynn, and Ben Wyatt. Could she be talking about the same Ben Wyatt from Parks and Recreation? According to Reddit, their ages check out. Ben would’ve been 26 at the time of the episode, making him a perfectly acceptable one-night stand for 29-year-old Rachel. But how does Leslie Knope feel about this?

8. JUDY GELLER HAD AN AFFAIR THAT PRODUCED MONICA.

Ross and Monica’s mom doesn’t even try to hide her favoritism. Judy Geller thinks Ross is a genius and Monica is, well, trying. (But could be trying harder.) One bonkers and since-deleted fan theory suggests Judy’s preference stems from a family secret: At some point in her marriage to Jack Geller, she had an affair, one she could never forget because it spawned Monica. Judy’s shame over this tryst is what causes her to lash out at Monica and praise Ross, her one 'legitimate' child.

9. THEY’RE ALL IN A PSYCH WARD.

What if Central Perk wasn’t a coffee shop at all, but rather the cafeteria at a mental institution? As one theory goes, all six main characters are suffering from personality disorders. They’re confined to a facility for treatment, and can only shuffle between their rooms (i.e. their “apartments”) and the cafeteria (i.e. “Central Perk”). This situation also explains why the group is so hostile toward new people. They’re not actually teasing Monica’s new boyfriend; they’re attacking anyone who tries to take one of the friends out of the mental hospital.

10. JOEY REALLY WANTED SOME PANCAKES.

This very silly—but very solid—fan theory is centered on Joey’s love of food. In “The One With Ross’s Library Book,” Joey has a one-night stand with a woman named Erin. He doesn’t want to see her again, and asks Rachel to break the news to her over pancakes. Apparently Chandler used to do this when he lived in the apartment. He’d even save extra pancakes for Joey. Rachel refuses to be a part of this, but once she’s left alone with Erin, she feels bad and offers to cook. Things escalate over the episode and pretty soon, Joey is the one who’s too clingy for Erin. Rachel has to tell him and, feeling bad yet again, she offers pancakes. Reddit claims this was all just a plot for pancakes. It kind of adds up: Joey can’t cook but likes to eat, and he has enough soap opera money to pay an actor (Erin) to play a part in this conspiracy. So he cons his roommate into making pancakes, twice, in a ruse that’s both delicious and diabolical.
