Step by Step - Season 1 Episode 19

Frank's contractor friend, John Patterson, invites him and his family to join an exclusive country club. While the Lamberts and Fosters engage in a series of gags, Dana fumes about having to come along in the first place; she's sure she'll be embarrassed by Frank's oafish, clumsy ways. However, she winds up sticking up for her step-father when she finds out the only reason Patterson invited him to join was to make him the butt of cruel jokes.
