The Back Nine (S01E14)

The Bird-Kersees and the Weavers have been invited to an open house for a new country club. The Weavers tells the Bird-Kersees it's snobby and stupid, not worth anyone's time...but then Marty decides he wants to belong -- he's never had the chance to join a country club before. They sneak out later to attend alone so the Zabvronians don't embarrass them. They show up anyway, fresh off learning about the concept of race, and studying up on some easy stereotypes so they can help themselves fit in. It probably wasn't the best idea. (ABC TV Network)
