Do not try this at home. Instead, sit back, relax and watch as 20 dimwitted thrill seekers harm themselves in all sorts of creative ways on World's Dumbest Daredevils 2. Featuring a dung diving sports fan, a downhill couch race, kayaking off a cliff, dirt skiing, man versus marlin (the marlin wins), woman versus killer whale (the whale wins), Richard Branson's bum-scarring leap off the Palms Casino in Vegas and the longest ski wipeout you will ever see (it's still going on). If there's a dumb way to hurt yourself, these daredevils have tried it. With play by play commentary by our daring celebrity cast, including Danny Bonaduce, Todd Bridges, Tonya Harding and Leif Garrett.
