World's Dumbest : Season 12 Episode 16

TruTV's got startling video of 20 daredevils, bashing themselves silly in pursuit of that ever-elusive adrenaline rush. Each is dumber than the last, including a hung-over hang-glider, several BMX klutzes, and a naked motorcycle stunt guy who gets road rash in the worst possible place. Plus we've got commentary from our usual crew of celebrity thrill-seekers, including Tonya Harding, Todd Bridges, Danny Bonaduce and Daniel Baldwin.
