My uncle used to work at some mental ward or something up in New Jersey. He told me this story about this guy named Michael who was accepted into some huge music college when he was only like 16. Apparently he was amazing. Well, one day he was at some place, and some people put a huge dose of LSD into his drink that he left sitting out when he went to go to the bathroom. After that, I don't know the exact details, but he ended up in the mental ward, he wouldn't talk, it made him mentally handicapped. Well, the hospital or whatever had a piano, and he would sit there just banging his hands on random keys. well, workers (not my uncle) would taunt him and tell him he couldn't play. After a while of that, I guess Michael started playing, and it was amazing. Shortly after, he threw a chair at my uncles back, for no reason at all, and it caused my uncle to have serious back injuries. This was around 20 years ago, and my uncle still has back problems. My uncle's not mad at the guy, because he didn't know what he was doing, but my uncle would constantly tell me that story (he's really protective and paranoid) when I was a kid, so I wouldn't leave my drink sitting out at a party or something, for fear someone would do that.
