I once went to a crowed midnight movie showing of the 1950's "It Came From Outerspace". The crowd seemed quite intoxicated and so I missed the first 40 minutes of the movie's dialog because every few seconds someone would stand up and yell SHUT UP and then someone else would yell back from the other side of the theater NO YOU SHUT UP. It was terrible and amusing at the same time.
