Hansen explained to investigators how he would abduct women at gunpoint, fly them out to his remote cabin in the woods, strip them and sometimes blindfold them before sending them off running into the woods. After giving them a head start, Hansen would then stalk and hunt them down like an animal in the kind of twisted human safari that you probably thought only existed in the dozen or so movies that have featured twisted human safaris.

"My real dream was to hunt Van Damme."

And yes, in case you were wondering, he had in fact been doing it a while. Authorities had expected to charge Hansen with four murders, so it came as a surprise to them when he admitted to around 21 (but really, you can't be totally sure of the number when you're keeping track of something as mundane as how many people you've hunted down and shot). His hobby got him sentenced to 461 years plus life in the big house. And in case you thought we were joking about all the movies that get made about this type of thing, the movie about this case comes out next month, in which Hansen gets thwarted by Nicolas Cage.

Keep going.

Dr. Harold Shipman was that friendly neighborhood doctor, who always had a lot of trouble with patients dying under his care.

"The ones I'd let go probably wished they were dead after they saw my rates."

Nobody knows whether Shipman started murdering people in Yorkshire, but after he started work at Donneybrook Medical Center in Hyde, he was well on his way to becoming the most prolific serial killer in British history. Colleagues probably thought he was taking it awfully well when a disturbingly high number of patients kept suddenly and unexpectedly dropping off on his watch, but a lack of evidence or any perceived motive kept the authorities from linking him to his crimes and probably just thought he was just a really shitty doctor.

"I'm telling you people die from athlete's foot all the time."

The only reason he got caught is because he got greedy; when a wealthy former mayor wound up on Shipman's slab, he stupidly forged her will to make it look like she left her fortune to him. Unfortunately for him, he wasn't as good at forgery as he was at injecting old people with poison. When Grundy's relatives became suspicious about why she had inexplicably left everything to the family doctor, an investigation began to unravel Shipman's crimes. Upon exhuming his patients, they found that a terrifyingly large number of them had died of morphine overdose. How many? They were able to pin 15 deaths on him officially, but further investigations revealed he may have killed up to 250 fucking people.

After being given 15 life sentences, Shipman apparently went into murder withdrawal and managed to find one more victim: He killed himself in his cell.

Charles Albright was a pretty swell guy. He knew several languages and was a former science teacher. He was well spoken, charming and lived happily in a committed relationship. He was a football coach, helped with Cub Scouts and was always willing to lend a helping hand to a friend in need. He was kind to children. Oh, and he also killed prostitutes and cut out their eyeballs.

"Please, like you people don't have any quirks."

As he's never admitted guilt, we may never know for sure exactly why Albright had this particular compulsion, but looking at his past we can make a few guesses. As a kid Charles was adopted into a stable (if not overly affectionate) home, where he took up an interest in hunting. He would skin and stuff the animal carcasses he brought home, but his parents were too stingy to allow him to spend their hard earned money on something as frivolous as realistic glass eyeballs, and so he had to make do with buttons. Well ... that's a little weird, but not serial killer-weird, right?

But then when he was in college, Charles had a friend who had recently broken up with his girlfriend and had thrown all the photographs he had of her in the trash. Charles retrieved the photos, cut out all the eyes, then pasted them all over his friend's room. At this point, shrewd detectives might come to suspect that he had a thing for eyeballs.

Fast forward to 1990, when a prostitute was found dead in Dallas. When the coroner lifted back the deceased woman's eyelids to check the eye color, they discovered that that there were no longer any eyeballs to check, which surely had to make a normally disconcerting workday even worse.

"Man, fuck Mondays."

Two more victims soon turned up eyeless, earning the killer the unimaginative press nickname "The Dallas Ripper." But, after rushing his third murder and leaving behind some damning forensic evidence, police soon arrested and charged Charles Albright. Since then, he's spent his days in prison, using his time productively. Just kidding, of course he's drawing eyeballs.

The Benders kept up this macabre business venture for 18 months, until they made the mistake of doing the old "stop, hammertime" on one Dr. William York, a brother of an army colonel who later formed a vigilante group to track down the missing man. Their search led them to the Bender homestead, but when the Benders realized they were about to get sprung (and this was one problem they wouldn't be able to solve with hammers) the family fled in the middle of the night. Authorities discovered the burial fields, but they never found the family. What became of them after that? Nobody knows. Take a few minutes to try to imagine an ending to the story that isn't terrifying.

British Colonial authorities eventually caught up with Behram, whereupon he immediately violated the "thug life" credo by snitching out his partners in crime. With his help the Thuggee Cult was effectively stamped out and the reign of terror brought to an end. It was not so easy, however, to get rid of the Anioto cult in Nigerial.

That one was discovered in the early part of the 20th Century, when British colonial administrators found people were being slaughtered and children going missing by the dozen in what was described by witnesses as attacks by "man-leopards." The rumors turned out to be true -- at least, in the sense that they were a bunch of dudes dressed up like leopards.

"Man, I really hope it's not breezy tonight."

They were members of the Anioto, a cult of leopard-worshippers. They had apparently been around for centuries and are believed to have started off as devotees of the Egyptian god Osiris. The men believed themselves to be were-leopards, though in reality they just wore cloaks made from leopard skins, and strapped claws and knives to their hands. Apparently, whenever they faced some local problem like illness or failing crops, the Anioto knew exactly what needed to be done: dress up and find a human sacrifice.

Forty-eight killings were committed in 1946 alone. In 1947 there were another 43 and most troubling to the white colonists was the realization that the violence now seemed to be directed at them. Cultists were rounded up and executed in an attempt to prove to local chiefs that they weren't immortal supernatural leopard people. Not much has been heard from the Cult of the Leopard since the brutal crackdown in the late 1940s, but- Oh, wait, no, a kid was killed by a cult priest in 2011.

Elizabeth Bathory was a Hungarian countess from back in the 1500s who has the distinction of being widely regarded the most prolific serial killer in human history. Nobody even knows how many people met their end in Bathory's castle of horrors, but estimates usually get up to around 650 before they lose count and round it up to the nearest thousand or so.

A lot of what we know about Bathory is probably trumped up, because back then, history tended to get mixed up with folklore, especially when you're talking about someone who might have leaped out of a Bram Stoker novel. And since one witness reported seeing Bathory having sex with Satan one day, we can deduce that some of these reports were unreliable.

"Don't be absurd -- it was just a handjob."

By all accounts, she was a vain and beauty-obsessed aristocrat who would have been at home in any one of Grimm's fairy tales. The popular account of Bathory's life is that the aging countess became obsessed with trying to reclaim her youth, and settled upon bathing in the blood of her young female servants, which probably made a lot more sense in the 16th century. But researchers who try to stick to the facts as much as possible admit a more down to earth scenario might be that she was just a terrifyingly brutal bitch going through the worst mid-life crisis in history.

Either way, the one thing scholars agree on is that Bathory seemed to really get off on torturing young women to death, and witnesses reported that her interests were as diverse as severe beatings, burning, freezing and biting her victims' faces. It says a lot for the quality of investigative journalism that girls continued to seek employment in Bathory's torture castle despite the suspiciously high turnover rate.

Eventually the King decided that he should put a stop to this before she reduced Hungary to the biggest sausage party in Europe, but nobody wanted to put her on trial because it might embarrass some rich people to try one of their own. So Bathory was put on house arrest for the rest of her life, which due to 16th-century life expectancy, thankfully wasn't long.
