I'll bet you missed the new Bear Grylls (however you spell that) reality show. One of the "survival tasks" was to pee in a jar, add muddy water, heat it as quickly as possible to XXX degrees for a few seconds, then chug it down. The first one done was the winner. Survival skill? Yeah, right, Bear.

What a stupid show. I would have peed on Bear myself, then thrown him into the fire until HE heated up to the required temp.
