1. Bob Dylan (1998)
A shirtless Michael Portnoy hopped on stage while Dylan performed "Love Sick" in 1998. With the words "Soy Bomb" written across his chest, Portnoy managed a few moments of erratic dancing before he was escorted off stage. "Soy Bomb is a dense, nutritional, transformational life explosion," Portnoy told Extra the next day during an interview. "That's what I think music and art should be."
