Wasn't the Joker thing just a Tim Burton movie exclusive, or did it happen in one of the retellings in the comic books? Because to my knowledge the guy who killed his parents was just some random thief with a gun like in the Christopher Nolan movies. I guess they plan to make it larger fry this time around.

And I don't think it was the Penguin. Too tall. And I guess the guy has a thing against killing kids since he left Bruce alive. "I really hope that kid doesn't grow up to take revenge on me or anything."
