Season 6: Episode 126: Surf's Up
Cliff buys a refrigerator for Theo's apartment. He is upset to learn that Clair has already been to the apartment, while Theo has failed to invite Cliff because he is worried that he will bore his friends. Cliff angrily heads over to the apartment and demands to come in. He takes pity on Theo and cuts short one of his tales. However, Theo's roommates find Cliff to be very interesting and keep pleading with him for more stories. Theo is impressed, and later tells Cliff that this is the first time he has seen him as a friend. Theo and his roommates get evicted after re-creating one of Cliff's stories by dumping soap and water on the floor and sliding around with sponges tied to their rears. They end up damaging the landlord's ceiling. Theo must move back in with his parents. Clair pressures Cliff to resolve the situation. Cliff goes to see the landlord and offers to pay him more each month if he allows the guys to return.
