2. Psycho
The original psycho was a (wo)man called Ed Gein, who was also known as The Mad Butcher. His story came to the limelight in 1957 when he was arrested for committing two murders and digging up the corpses of several women who reminded him of his dead mother. It gets better. After exhuming these corpses, Gein skinned the corpses to make lamp-shades, socks and even a 'woman suit' in the hopes of becoming a woman. While searching the man's house for a missing woman, the authorities not only found the woman (who was hung upside-down by her ankles and dressed like a deer) but also a belt made from female human nipples, human skin that covered several chairs and a few decapitated heads of women. It was found that upon the death of his mother, Gein had decided that he wanted a sex change and his own plagued head, a woman suit was the best option to do the same. The court found this serial murderer and grave-digger not guilty on the grounds of insanity. He was placed in a mental hospital, where he spent the rest of his life before he eventually died due to cancer. Whether he smiled creepily at the authorities the way Norman Bates did in the movie is up for debate.
