Port-a-Potty Bungee Jumping With Britney [Video]

Britney Spears is making the rounds promoting her new music. But she made the mistake of stopping by Jimmy Kimmel live and meeting up with Johnny Knoxville from the show "Jackass".  The result? Port-a-Potty bungee jumping! Check out the video. Come to think of it, I may have seen this done at a Bills game. (Just kidding!)
