J.T. helps Al come up with a name for her band and he becomes the manager. The band gets to perform at the bowling alley where Frank just did a remodeling job. The other four girls in the band get the flu and J.T. is forced to get Dana and Karen as replacements. Since no one else is available, J.T. and Cody dress up as girls. The crowd finds out J.T. and Cody are guys and Carol saves the band by performing herself. There is a mouse loose in the house. Frank wants to kill it but Carol believes the mouse should live.

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.
