Having performed enough stupid stunts to fill two 3D movies, Johnny Knoxville and his fellow foolhards do just that - except this one's not in 3D. In this steaming-fresh pile of gross idiocy, the lads subject themselves to trials by everything from tasers to snapping turtles, plus all the below-the-belt trauma they can take without going to hospital. Just remember, this will hurt them more than it'll hurt you.
