In 1989, a guy called Michael Anderson Godwin was waiting in his death row cell for an execution day, as he was supposed to be sent to the electric chair.
One day, his TV broke and the guy decided to try to fix it playing around with the cables, or more specifically, chewing on them while he was on the toilet. The Universe at that point must have decided that the Criminal Justice system was a bit slow, because with the metal toilet as a conductor, Godwin died by electrocution. Oh well, it was going to be a matter of time anyway.
