While this does not have to have drinking involved, you do need an empty keg and some drunk people. The rodeo takes place when the keg is finished and someone volunteers to ride it. Four people hold the keg in the air on its side. Then one person, preferably someone smaller, gets on the keg and rides it for as long as possible, like a bull at a rodeo. Careful not to land on your head. OPTIONAL: leave some beer in the keg and have the person riding the keg drink out of it at the same time.
