S3, E17: The aliens decide that they need to be a two-car family, so Sally, Harry and Tommy go shopping. Sally sees a Viper and falls in love; she has to have it even though its way out of their price range. While standing in line at the movie theater, Dick meets Anita, a woman who immediately begins coming on to him. After the movie they have sex in the Rambler, and Dick thinks hes gone to heaven. Hes amazed and pleased when Anita says it was a one-time thing. Sally and Harry start telling everyone theyre getting a Viper. Tommys against the idea until August says that the car will impress all the bimbos at school. Dick tells anyone who will listen about the joys of casual sex; the other aliens, Mary and Nina all hear more about his tryst with Anita than they care to know. In class he continues talking about his one-night-stand in so much detail that Bug recognizes the woman as his mother. When Mary finds out, she angrily reproaches Dick for being so insensitive to Bugs feelings. Tommys having a great time impressing Tina (one of the so-called bimbos) with stories about the Viper hes about to own. Tommy tells Dick theyve got to get that car because his love life depends on it. But when they consult with the salesman, he informs them that all they can afford is a Nova. Sally tells him hes ruined the experience of car shopping for them, and theyll look elsewhere. Bug and his classmates are amazed when Bug, who usually fails, receives and A on a physics exam; the class accuses Dick of favoritism, and when Mary hears about it, shes even more scandalized. Dick tells Bug hes sorry for what he said about his mother and also that hes compelled to give Bug the F that he deserves. After Dick is beaten up by Bugs father and brothers, he tells the aliens that theres no such thing as casual sex; there were so many repercussions.
