These people volunteered to stand in the Rodeo ring while a bull charges at them! They have to stand in the circle and try to grab a $100 bill attached to the bull. If they step out of the circle, they are disqualified. It's called Cowboy Pinball and the results are just what you thought would happen. People getting hurt. One guy gets knocked out completely. The first bull wasn't mean enough so they actually took him out and got a meaner bull. You can advance the video to 4:21 to see the second bull start taking everyone out. You've got to watch this video. And wonder at the sanity of the people involved.
