Plot summary
Earl attempts to cross off another list item for bullying a classmate from when he was briefly in Catholic school, Wally Panzer ( Matthew Willig ), whom Earl dubbed "Pansy." Wally has since become a very strong gym rat, so Earl, under the alias Cliff, agrees to help him to re-enter the Mr. Camden bodybuilding competition. Meanwhile, Randy takes drastic measures to avoid Joy's bullying, trying out shark adrenaline; however, he ends up going crazy when he injects the entire vial. He reveals that Cliff is Earl, and then goes on a rampage, fighting Wally, and then going after joy.
