What should the title of my paper be?

I am writing on the differences and similarities of the 3 Joker characters in the following films Batman(1966) played by Cesar Romero, Batman(1989) by Jack Nicholson, and TDK by Heath Ledger. I am looking for a cool title for my paper. Also if you have any ideas that would go along with my paper that I could discuss that would be great to. Thanks.
