If you need a reminder of the human race's capacity for stupidity, consider this story, from SanLuisObispo.com:
Pillers, Keiffer and friend Elliot Tuleja were drinking at a house in Grover Beach on Jan. 18 when Tuleja passed out. Pillers and Keiffer decided to play a practical joke on him...
“They were drinking, and one of the guys passed out. So (the other two) said, ‘Let’s do something. I’m going to look for rotten fruit to (put) up in his socks.’
“The other guy found a bottle of cologne and poured it onto his pants. The one guy said, ‘That’s funny,’ ” Gran said. “The other guy said, ‘That’s not funny. If you lit it on fire, that would be funny.’ ”
One of the men then allegedly lit Tuleja’s groin area on fire where they had poured the cologne. Tuleja woke up, and all of the men attempted to extinguish the blaze. Tuleja suffered second-degree burns on his testicles and third-degree burns on his inner thighs, Gran said. Tuleja did not believe his friends intended to harm him, Gran said.
I'm labeling this a "prank gone wrong," though I can't imagine how it could have gone right. Pillers looks just like I imagined he would in his mugshot.
