Performers 12 World's Dumbest : Season 13 Episode 8

Sometimes the best performances are the worst performances. Tru TV has rounded up 20 entertainers who fail in hilarious ways, and we're counting them down: We've got butter-fingered figure-skaters, busted-ass break dancers, klutzy beauty pageant contestants, and comedians who are only funny because they're so not funny. And our celebrity cast is here to heckle, including Leif Garrett, Danny Bonaduce, Tony Harding and Todd Bridges.
