All aboard The Love Boat for our season 3 finale. In this fascinating, timely, yet very much of its time episode: Marcia Brady competes in a beauty contest and contends with a jealous boyfriend (Bobby Sherman); our man DVP (Dick Van Patten) plays a disgraced politician courted by Mama (Vicki Lawrence) for the wrong reasons; and Isaac (Ted Lange) learns about his people from an unlikely source. Plus, Rick argues that The Love Boat is the quintessential TV show, and we try to figure out what Gopher does.
