There's a video on YouTube of a Cleveland Browns fan being dared to dunk his head into a bucket of urine for $450. Some of his friends kept telling him not to do it, but eventually...he did! This is flat nasty; but for your viewing pleasure, here it is!

As for why there was a five-gallon bucket filled with urine in the first place...it was at a tailgate. A nasty, nasty tailgate.
