Molly is mortified to learn that her parents are planning to appear in a local theater production of "Hair," which may include a nude scene. Meanwhile, Fred fumes over Harriet's attraction to his best friend.

Molly joins the school's cheerleading squad to be closer to Nick, but making the team comes at a price---her availability to the chess club. Elsewhere, Jerry and Rick grow mustaches as father and son compete to be more attractive to women.

Molly gets little help from her family as she tries to deal with her breakup with Nick---they're much too busy preparing for Halloween. Meanwhile, Harriet waits for a call back from a gentleman suitor.
