SpongeBob thinks no one will recognize him in his round pants, so he goes to the Krusty Krab to get hired again. Mr. Krabs does not pretend to not recognize SpongeBob and tells him to get to work. Squidward shows SpongeBob how to be a bad worker without telling him in hopes of getting him fired. Mr. Krabs catches Squidward and SpongeBob sleeping on the job and gets mad. SpongeBob tells Mr. Krabs that he can not be "SpongeBob SquarePants" because of his round pants. Mr. Krabs tells him to just take off his round pants, leaving him in his underwear. Sandy teases SpongeBob by calling him "SpongeBob UnderPants," making him scream and ending the episode.
