This episode was originally intended to end showing the coffee shop under water in the year 2000; the idea was discarded due to time and budget constraints.
Kramer (Michael Richards) mentions Newman (Wayne Knight) being "stuck between the moon and New York City"--a reference to "Arthur's Theme (Best That You Can Do)" by Christopher Cross, whom Newman booked for his party.
When Valerie (Lauren Graham) and Jerry (Jerry Seinfeld) are watching a movie, the soundtrack from Nixon (1995) is audible; it was first heard in episode 7.14, The Cadillac (1996).
