Alex tells Mallory, "Jeff has been away at Princeton. He's mingling with people of the world, jet setters and cover girls." He may be referring, in part, to model and actress Brooke Shields, who began at Princeton in 1983, the same year as this episode.
When Jeff proposes to go steady with Malory, he pins his French club pin on her sweater.
Alex goes to the homecoming dance on a blind date with a girl named Inga. She never makes an appearance on screen. Her voice is heard during the dance as a call to swine.
