The great thing about the list is, it's clickable! Want more details on the wacky story? Just click!
My fav:
2003: Brian Wells, a pizza delivery man in Erie, PA, was killed by a time bomb which was fastened around his neck. He was apprehended by the police after robbing a bank, and claimed he had been forced to do it by three people who had put the bomb around his neck and would kill him if he refused. The bomb later exploded, killing him. In 2007, police alleged Wells was involved in the robbery plot along with two other conspirators.
(Edited to change annoying thread title)
(Edit to add: Boy, Mel Gibson got off easy at the end of "Braveheart", compared to what Willy Wallace really had to go through. Yes, I know that they originally filmed it for authenticity, and had to edit it dramatically because film-goers in the test screenings couldn't handle it.)
