Trivia

 * Three endings were filmed, each revealing a different character as the actual murderer. When the episode aired on NBC-TV on 16 February 1988, viewers were given the opportunity to call a 900 toll number and vote for the killer. All you had to pay was fifty cents and the suspect with the most calls was the murderer, and the proceeds were donated to charity.
 * All three endings are available on the DVD.
 * Kari Lizer does not appear in this episode.
