Human Wrecking Balls

Each episode contains a "Challenge" in which the Pumphrey brothers compete to either do or not do the episode's "Big Break". The big break is what Chad considers to be the most difficult thing for a human to break. The only time the winner of the challenge got to do something other than the big break was in "Trashing Hotel California" when the winner got to throw the television out the window. The first Episode of Season 2 saw a different format, where the loser had to do the "Big Break". (Even though Paul lost the challenge, but due to an injury while breaking the big propeller Craig did it instead.)
