It's a fun and zany messy guessing game. Rafa and Carlos, wearing shorts, have to lower themselves into a variety of messes... pizza, creme eggs, cake, peanut butter and loads more... and guess the mess using only their arses.

Guess right and you pie your opponent, but guess wrong and he pies you. Both boys' shorts end up coated with mess (and if you like messy shorts, there are loads of close-ups in the video) and both boys end up covered in pie.

The overall loser then gets a further helping of pies, including a climactic pie sandwich.
