I'm actually quite impressed with the levels of skill involved in that! I was channel flicking last night and stumbled upon rude tube. A bunch of Jackass wannabes. Two of them positioned themselves with their legs in the air, a plank of wood was placed between them like some sort of human shelf - so the wood was resting on their wood so to speak. Then a third one jumped off a ladder landing on the plank with his plum sack - no doubt sterilising the three of them for life. Next to that the baseball stunts looked quite safe and sensible.
