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.
The revolving rooftop restaurant overlooking Times Square to which Newman refers is The View in the Marriott Marquis.
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).
