Jean Claude Van Dam, Steven Segal, and Arnold Schwarzenegger all decide to go out trick-or-treating as musical composers for Halloween. They go into a costume store and look for masks.
Jean Claude sees a costume that he likes and says, "I think I'll go as Beethoven."
Steven Segal sees a costume that grabs his attention and says, "I'll be Mozart."
Arnold eventually found one that he liked. He picks up a costume and said, "I'll be Bach."
