The main event is a wrestling match on top of a giant hamburger. In the episode "The Fry Cook Games," SpongeBob and Patrick face off. In the end, Patrick and SpongeBob both set aside their differences of employers, once they realized they are wearing each other's colored underwear. To the displeasure of Mr. Krabs, Plankton, and the crowd, they both leave the stadium holding hands.
