Bull Plays Last Man Standing Like A BOSS

You go to a rodeo and they ask for volunteers to play a game...how drunk do you have to be to play this game of Last Man Standing?  Someone posted a video of contestants at a rodeo doing just that... playing a game of "last man standing" with a real live bull.  So the object is to stay inside your own ring as the bull charges right at them.  The last one still in his ring wins. They're basically target practice for the bull who picks them off one-by-one sending them flying into the air.  Who would do this?
