Because Elaine is dating a man with the same name as New York serial killer Joel Rifkin, she wants him to change his name to a less embarrassing one and suggests O.J. About six months after this episode aired, O.J. Simpson was arrested and charged with the murder of his ex-wife and her friend. His ride in the white Bronco is parodied later in The Big Salad (1994).
Lisa Pescia plays the role of Lisa and appears in the next episode The Cigar Store Indian (1993) as a completely different character called Joanne.
Jerry brags that he hasn't vomited "in thirteen years" since June 29, 1980, longer than the eight-year stretch of Elaine's boyfriend--who happens to have the same name as serial killer Joel Rifkin. Rifkin himself was finally apprehended June 28, 1993, thirteen years less a day from Jerry's last vomit.
