Bull Fisting is an extreme sport similar to bull riding, but in which participants shove a fist in a bull's ass and keep it in as long as possible. Points are awarded for time spent inside the bull and arm length inside the bull. there may be variations in which there are two contestants; one riding the bull and the other with his hand in its ass. this sport, similar to bull riding, also employs rodeo clowns, usually midgets that climb inside a bulls ass during intermission.
