The Riddler: Did anyone ever tell you you have a serious impulse control problem?!
The Riddler: Riddle me this. Riddle me that. Who's afraid of the big black bat?
The Riddler: Now, the real game begins.
The Riddler: Why can't I kill you? Too many questions. Too many questions.
Batman: Poor Edward. I had to save them both. You see, I'm both Bruce Wayne and Batman. Not because I have to be. Now, because I choose to be.
Edward Nygma: And you are?
Chase Meridian: Chase.
Edward Nygma: And what a grand pursuit you must be.
Batman: Wait. I have a riddle for you.
The Riddler: A riddle? For me? Really? Tell me.
Batman: I see without seeing. To me, darkness is as clear as daylight. What am I?
The Riddler: Oh please. You're blind as a bat!
Two-Face: Why can't you just DIE?!
Alfred: I'm sorry to bother you, sir, but I have some rather distressing news about Master Dick.
Bruce Wayne: What? Is he all right?
Alfred: I'm afraid Master Dick has... gone traveling.
Bruce Wayne: He ran away?
Alfred: Actually, he took the car.
Bruce Wayne: He boosted the Jag?
Alfred: Not the Jaguar. The other car.
Bruce Wayne: The Bentley?
Alfred: No, sir. The *other* car.
Chase: What is it about the wrong type of man? In grade school, it was guys with earrings. College, motorcycles, leather jackets. Now, black rubber.
Batman: Try firemen. Less to take off.
Bruce Wayne: I've really got to get you out of those clothes.
Chase Meridian: Excuse me?
Bruce Wayne: And into a black dress. Tell me, doctor. Do you like the circus?
Edward Nygma: [to Two-Face, as Batman interrupts a party] Your entrance was good, his was better. The difference: showmanship.
Chosen answer: Batman talks like that because if he talks like Bruce Wayne (Val Kilmer's voice) his voice might be recognized, leading to Batman's identity being revealed.
