Fred Ottman

While making his WCW live debut as The Shockmaster (complete with a silver glittered Star Wars stormtrooper helmet), he was supposed to burst through the wall onto the set of Ric Flair's "A Flair For The Gold" show to help Sting confront the "Bad Guys" (Sid Vicious, Booker T and Stevie Ray). Instead, he fell literally head-over-heels through the wall and his helmet fell off revealing his identity. Even Jesse Ventura (who was commentating) couldn't help but crack up laughing. Needless to say, his character was repackaged as an Electric Company worker and he was jobbed out months later.
