1. Soy Bomb!

During the 1998 Grammy Awards, while legendary singer Bob Dylan was performing "Love Sick", a shirtless man with the words "Soy Bomb" written on his chest jumped on stage and began awkwardly writhing about as if he were trying to perform a martial arts demonstration while having an epileptic seizure.  What was supposed to be Dylan's comeback performance suddenly became a freakshow as Soy Bomb a.k.a. New York City-based performance artist Michael Portnoy wriggled on stage for almost a full minute before being taken away by security.
