The guys split the van front/rear, with the first to leave the van losing. Kenny equipped the back of the van with a television, stove and other equipment, while Spenny drove and stayed in the front seat.

In perhaps the silliest competition to date - if that's even possible - the dysfunctional duo wear hot and itchy gorilla suits in the middle of summer - the first one to take off any part of the costume is the loser.
