This television episode refers to:
September 10, 1988
Throughout the episode, big numbers appear on ordinary objects counting down from 50 to 1. This is a countdown from the beginning to the eventual bad news which is told right after the "1" is shown. The countdown was an idea taken from the 1988 film Drowning by Numbers; through the course of that film, the numbers 1 to 100 appear in order, sometimes seen in the background, and sometimes spoken by the film's characters.
