There's a video on YouTube of a Cleveland Browns fan being dared to dunk his head into a bucket of #1 for $450.  His friends kept telling him not to do it . . . but eventually he did, and it was pretty disgusting.

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

Here's the link to the video... like I said, it is pretty gross.
