Johnny Knoxville went on Jimmy Kimmel last night and for whatever reason teamed up with Britney Spears to pretend she did a skit called Poo Cocktail Supreme from Jackass 3D.

Knoxville acted like it was a “deleted scene” but one too many “yeah yeahs” gave it away. Not that he was trying to make it seem real, but a little more effort would have been nice. That and the whole thing looks fake. They threw blue water on the camera lens to make it look like Britney was actually doing a stunt while using footage from the real stunt.

Next time they should tell her it’s fake and then actually do it. But instead of poo, have it be chocolate pudding. By the time you open the door to the port a potty, Britney will already be down on her knees lapping everything up. Except the audience won’t know it’s chocolate.
