Yeah, but what if Bill Murray was an older Batman, who had quit Batmaning, but, then he starts Batmaning again because the voice of Hitler was in the taste of his hotpocket, while bananas shot out of the cuss words that were Tattooed in the leg fat that was written about in his grandfathers ancient stone diary?
Then maybe he could try to sell all of the bones in his body.
Then he finds out that he is really a Belmont, and he destroys Dracula with a pile of jury duty during Daytime hours.
Then he can pick at his scabs for the rest of the movie.
Maybe they could paint Danny Glover green, and he could play the part of all of the money used in the movie. I doubt he has anything else going on.
