Isn’t it a shame that the Joker never had a real theme song? We changed that (kind of) by combining Joker’s lines from movies, cartoons and tv shows to a catchy Joker-esque circus tune in this musical supercut. This video includes epic laughter and dialogue by Mark Hamill, Heath Ledger, Jack Nicholson, Michael Emerson, Cesar Romero and Jared Leto. Competitive as Batman is he made his own song aswell.
