Charles Grodin appears as himself in this episode, endeavoring to spread some genuine Christmas cheer throughout cynical, jaded Hollywood. When Grodin shows up at Bardwell's Department Store, Laverne (Penny Marshall) jumps to the wrong conclusion that the actor wants to date her, while Shirley (Cindy Williams) labors under the misapprehension that Grodin wants her job. Before the inevitable cross-purpose conversations, bitter arguments and warm-hearted reconciliations play themselves out, Lenny (Michael McKean) contributes his bit to the Holiday season by giving his roommate Squiggy (David L. Lander) a free shampoo! ~ Hal Erickson, Rovi
