The eighth anniversary special of Late Night with David Letterman, airing in 1990, began with a scene at Cheers, in which the bar's TV gets stuck on NBC, and all of the bar patrons decide to go home instead of staying to watch David Letterman. The scene was re-used to open Letterman's final episode in 1993.[citation needed] A similar scene aired in the Super Bowl XVII Pregame Show on NBC, in which the characters briefly discuss the upcoming game.[citation needed]
