Stripteaser (1995)

Synopsis
Murder, lurid sex, and clowns drive this exploitation flick in which a psychotic loner terrorizes a strip club, "Zipper's Clown Palace," and takes everyone hostage at gun point. He then proceeds to force a weedy nerd to have sex with a stripper, while quizzing his frightened prisoners on trivia about the 1960s musical Gyspy. Duane Whitaker, who played Maynard in Pulp Fiction, wrote the script. ~ Jonathan Crow, All Movie Guide
