Annie's half-sister Lilly (guest-star Michelle Phillips, "Knots Landing" and musical group "The Mamas and The Papas") is getting married and wants their ailing father to walk her down the isle but Annie worries that the strain might be too much for him. Meanwhile, Fred (guest-star Al Ruscio) and Mrs. Bink (guest star Eileen Brennan) attend premarital counseling with Chandler, but Fred's mother (guest-star Carol Arthur) tries to put a stop to the wedding because she thinks Mrs. Bink is a gold digger. Lastly, Jimmy (guest-star Glen Poehlman) and Pat (guest-star Pam Rawuka), two mentally challenged people, decide to get married after just one date and ask Chandler to perform the ceremony, but Jimmy's parents (guest-stars Dick Van Patten and Patricia Van Patten) try to put a stop to it.
