33 I'm with Stupid

Patrick's parents come to visit him on Starfish Day. He gets SpongeBob to act dumb so his parents will think he is smart. His parents fall for the trick, but Patrick forgets about the plan and begins insulting SpongeBob. SpongeBob gets angry and tries to convince Patrick's parents that he is smart after all. Patrick's parents don't believe him, and think that Patrick taught SpongeBob how to speak in a matter of minutes. SpongeBob gives up and runs to his house. Patrick then realizes these parents are not his true parents. Two other starfish come to the door who reveal themselves to be his parents, and the fake ones leave.
