Thrillseekers 6

It's a thin line between brave and stupid, but we've got video of 20 people crossing that line and leaving it far behind. We're talking seriously stupid thrill-seekers, like an alligator trainer who's almost alligator lunch, a clumsy cliff diver, and an amateur stunt man who will probably never go pro. Joining in the bad clean fun is our celebrity cast, including Tonya Harding, Todd Bridges, Danny Bonaduce and Leif Garrett.
