Season 5: Episode 101: Rudy's All-Nighter
Theo is frustrated when he receives a D on his first paper in English composition, as well as many critical remarks from the professor. He must work all weekend to revise it. Rudy invites her friend Caroline to stay the night. Cliff becomes somewhat annoyed by the fact that Rudy's friends always expect him to be funny and perform certain characters. He pretends to be depressed, but then delights the girls with his "pirate" impression. Rudy and Caroline stay up extremely late and get on everyone's nerves with their obnoxious behavior. Caroline, the daughter of a newspaper editor, offers Theo tips for his paper. Caroline wakes up Cliff in the middle of the night and demands to go home after getting into an argument with Rudy. By the time Cliff has called her parents and is ready to drive her, they have already made up and gone to sleep. Cliff is left exhausted. Theo gets some feedback from his professor. He is surprised to hear that Cliff would be proud if he got a C on the paper, but Cliff feels that the fact that he is working is so hard is what is important. Theo vows that he will eventually get good grades.
