At this point they ran into a group of officers who were being filmed for a COPS-like show for the BBC. The cameras captured every batshit insane moment that came after that -- the video that follows at times looks staged as hell, but it isn't. There's a real murder conviction to prove it. That's just how British people talk.

As seen in the video, the twins were detained by the cops and appeared calm, until Ursula sprinted onto the highway and ran directly into the wheels of a truck.

Sorry, a lorry.

The cops hadn't even had time to react when, seconds later, Sabina did the same thing and was struck by a car.

But don't worry, the officer was able to keep the jacket safe.

That wasn't the end of it. Despite the whole "car just struck her" thing, Sabina got up and attacked the officers -- it took six people to contain her. Ursula was raging too and probably would have done the same thing if, you know, her legs hadn't been broken and stuff.

Afterward, Sabina calmed down and was behaving so normally that the cops released her the next day. This proved to be a huge mistake: Hours later, she murdered a man who offered her a place to stay and then launched herself from a 40-foot bridge. She survived, somehow, and was sentenced to five years in prison. Why only five years? Because lawyers had no trouble proving that she was crazy as all f**k when all of this happened. But, if Sabina was the crazy one, why did Ursula jump onto the highway, too? Neither of them had traces of drugs or alcohol in their bodies.

Although one of them could have very well been affected by gamma rays and then gotten angry.

According to psychologists, one of the twins suffered from a form of temporary insanity, and the other was "infected" by her twin's madness -- their bond was so strong that when one lost her s**t, the other did, too. They have both since been declared sane, but we're guessing they're not so big on family reunions anymore.

After this story was first reported by the press in 1979, James and James were contacted by psychologist Thomas Bouchard, who wanted to study how similar twins can be despite growing up apart. It turns out the twins had even more similarities: They both had dogs named Toy as kids. They both liked math and carpentry in school but hated spelling. They both had jobs in law enforcement -- Springer as a deputy sheriff and Lewis as a security guard. They both got headaches at the same time of day. They both had the weirdest reunion conversation ever after meeting a long-lost brother.

Via Dnatestingblog.com They both made vastly different but equally baffling hairdo choices.

This sounds like complete bullshit, but it isn't the only case of its type. Even when twins are raised under radically different circumstances, they still end up having a lot in common. Case in point: Oskar Stohr and Jack Yufe were also separated as babies, only this was in Europe, and in the 1930s. Stohr grew up in Germany and joined the Hitler Youth. Yufe was raised a Jew and moved to Israel. One drew swastikas in his notebooks; the other wore a yarmulke.

And yet, despite being as different as two human beings can be, when they met in their 50s they found that they spoke alike, liked the same foods, and shared oddly specific habits, like wearing rubber bands on their wrists or flushing the toilet before using it.

Via Developmental Psychology Yeah, we can see a Nazi doing that, but how do you explain Jack?

Experts think that this isn't so weird: Stohr and Yufe are genetically identical, so it's normal that they should react the same way when exposed to the same everyday experiences (foods, rubber bands, toilets). The fact that one was Jewish and the other a former Hitler fan is irrelevant, genetically speaking.

In total, Donald says he voluntarily served four sentences for Ronald, simply because he loved his brother and believed he wasn't ready for prison life. It all started in the '70s when Ronald signed up for the Army and went through months of training, only to decide at the last minute that he didn't want to be shipped off to Korea to serve as a helicopter mechanic. Ronald said, "What the heck, I'll go for you" -- he'd fixed a few cars in his neighborhood, so how hard could a helicopter be?

Since no one caught them (Donald became a crew chief in Korea), the twins kept pulling the ol' switcheroo every time Ronald got into trouble. Donald had some run-ins with the law himself and insisted that his bro was too soft and delicate to spend time in prison ... despite the fact that Ronald was a violent criminal who repeatedly threatened to murder his wife. When a judge told him to cut that s**t out and sentenced Ronald to six months in jail, Donald once again stepped up and turned himself in, pretending to be his brother. Apparently they didn't bother to check his fingerprints because they didn't know he had a twin, never mind one stupid enough to take his place.

Unfortunately for Donald and his prison-loving ass, Ronald got himself arrested five days later for attempted murder, battery, and robbery and was sentenced to 14 years inside, in addition to the six months he tried to skip. Investigators worked on the thesis that the twins had planned everything to give Ronald an airtight alibi to murder his wife, but eventually realized that it was a case of extreme brotherly love. Meanwhile, Donald still maintains that he would love to serve the jail time for his brother if he could.

Twins love to do everything together, but there's a point where you have to draw the line and give yourself some privacy, otherwise stuff like wedding nights and colonoscopies could get pretty uncomfortable. That line did not exist for identical-twin brothers Craig and Mark Sanders, who got engaged on the same day, got married in the same ceremony, and settled down to live in adjacent houses ... with a pair of identical-twin sisters. One couple then went on to spawn some identical twins of their own.

Barcroft via Telegraph Nobody's sure who gave birth to whom anymore.

This sounds like the plot of some terrible sitcom starring the grown-up Olsen twins (they're like 40 now, right?), with Charlie Day and Zach Galifianakis as the husbands, probably, but it's real. It was actually the wives who insisted on doing everything together -- poor Craig and Mark probably hate each other's guts by now.

Mark first met fellow twins Diane and Darlene Nettemeier at the annual Twins Days Festival in (of all places) Twinsburg, Ohio. Striking out and in need of some reinforcements, he rescued the situation by running back to his hotel room to inform his brother Craig that he had two blonde twins waiting for them at the bar. After the obligatory high-fives, the brothers hurried back and immediately hit it off with the ladies, with Craig hooking up with Diane and Mark with Darlene.

Craig Sanders via Nydailynews.com "Mark has never stopped reminding me that he got the hot one."

The couples started going on dates together and even shared their first kisses at a baseball game (presumably one of the couples just went along with it so it wouldn't be awkward). While on a double date at a casino, the twins won several thousand dollars and, deciding to take that as a sign, they all got engaged right there and then. Since Diane and Darlene had never lived apart, after they got married in a joint ceremony, Craig and Mark agreed to move into adjacent houses with no fences.

Diane and Craig later had twin boys, while Darlene and Mark gave birth to two non-twin girls, with one other kid thrown in there somewhere to ruin the perfect symmetry (great job, kid). Today they enjoy beating everyone else at Twins Days every year and confusing the hell out of neighbors.

Twins Jennifer and June Gibbons became notorious in the '80s when they carried out a two-woman crime spree at age 18 that resulted in both sisters being declared psychopaths and sent to England's most famous high-security hospital for the criminally insane. However, they already had plenty of experience being creepy before that: As kids they were known as "the silent twins" because they refused to speak to anyone but each other, and even then they used their own secret language that no one else could understand.

Via Almeida.co.uk They would have made terrific sidekicks for Two-Face.

Born to Barbadian parents and raised in Wales, Jennifer and June refused to read or write in school, but at home it was the opposite: They read voraciously and filled dozens of diaries with writing, including full novels with names like The Pepsi-Cola Addict and Discomania. Like all children, they liked to play games, but rather than settling for Barbies or Monopoly, they had bizarre rituals where they decided which one would wake up in the morning first or which one would breathe first, and the other one wasn't allowed to do anything until the first one did so.

Via Kimbofo Attempts to sell their idea to Hasbro were unsuccessful.

Their relationship was complicated. On one hand, they were best friends, and on the other, they occasionally tried to kill each other -- Jennifer tried to strangle June with the cord of a radio, and June responded by throwing Jennifer off a bridge. Their odd behavior escalated as they grew older and turned to petty theft and arson. It was at this point that their parents realized there might be something wrong with the girls and agreed to have them committed (and if they hadn't, the authorities probably would have insisted).

It was toward the end of their 14-year stay at Broadmoor Hospital that the twins would pull off their magnum opus. One day, they told their only friend, journalist Marjorie Wallace (author of their biography, published years earlier), that one of them wouldn't make it out of the hospital alive. Jennifer just looked at Wallace and said, "I'm going to die. We've decided."

Via Ham & High "I did dishes yesterday, so she kind of owes me."

You see, the twins had realized that they could never be free or normal as long as they were both alive, and so, according to Wallace and later interviews by a reformed June, Jennifer agreed to be the one to die. And what do you know, on the day that they were being transferred to a lower security hospital, Jennifer suddenly passed away from a rare heart problem that was never fully explained. As predicted, June became considerably less creepy after she stopped being a twin, and today she lives a quiet life with her family. Which somehow just makes all of the above even weirder.
