That’s Just Straight Up Piss [VIDEO]

I recently read an article about Bill Gates and some contraption that turns poop into drinking water and it reminded me of this video I saw back in 2008. HI-LARIOUS!  From Funny or Die. I remember the first time I saw it, I probably watched it 40 times in a row and laughing harder each time. Especially around the 1:02 mark when he screams and yells, "Ahhhh THAT'S PISS!"
