The two families each obtain invitations to join a country club. The Weavers attempt dissuade their neighbors from joining by explaining to them about the exclusivity of membership. The discussion focuses on different social classes of humans and the Zabvronians' "equality" standards. Each family agrees the discrimination is wrong and neither join—until Marty later informs Debbie that he wants to join. They sneak away to attend the club's open house to see their neighbors later arrive. All argue about class again, until the Bird-Kersees are accepted into the club but not the Weavers. Ultimately, neither family joins because of the issue of stereotyping.
