There is one mystery that has haunted humankind, left us forever grasping for a sense of order and resolution in the cruel and random chaos of existence. If we knew -- really knew -- the identity of the woman who plays the manicurist in A Night at the Opera, it wouldn't just satisfy our interest in Marx Brothers arcana. It would give purpose to the experiment of human life on Earth.
But, unfortunately, we still don't know. April Fools!
