The Solomons discover that everyone on Earth has roots but them. During a chat with Tommy's teacher Mr. Randell, Dick learns that the teenager isn't "fitting in" at school. "Of course I'm not fitting in," snaps Tommy, "to fit in, you have to be something." The question is, what to be? Dick grabs an anthropology book for the answer. "It's loaded with every possible genre of human," he marvels. "It's like a catalogue. We can take our pick." Dick picks the Italians because, according to a swooning Dr. Albright, they're the sexiest people on the planet. Meanwhile, Sally's swooning, too -- for Mr. Randell.moreless
Tommy asks Dick if he's still interested in Mary, and Dick pretends he couldn't care less; Tommy couldn't be happier. Sally likes her new job, but she's already been advised that she must learn to respect her co-workers. She takes this advice so seriously that when her boss starts hitting on her, she somehow thinks she's at fault. She goes to see Nina who quickly explains that her new boss is a creep and she's the one being harassed. Dick shows up and begs Nina to tell him who Mary's been seeing; Sally tells him that right now Tommy's at Mary's house. Dick rushes to Mary's and confronts Tommy who tells him that this is the happiest he's been since he arrived on this planet. He tells Dick that it's too late, that Dick already gave him the all clear. He tells Dick to leave or he'll call the cops. Sally threatens Webber with violence, and she loses her job. Dick shows up at Mary's again and starts fighting with Tommy over Mary. Mary tells Dick to grow up, but after putting up a good fight, Tommy tells Dick that he can have Mary back. Mary has no idea what's going on and is even more puzzled when Tommy tells her there's no hope for their relationship.moreless
