Batman: Let me make myself clear. There's no room for a Batgirl in Gotham.
Batgirl: That's cool, because it's Batwoman. As in I'm a grown woman and I don't need to listen to you.
Batman: Then for your own safety, if you don't listen to me, I'm going to have tell your father, Ms. Gordon.
Batgirl: Ah... You must have me confused with some else.
[silent for a second]
Batgirl: Dude! You just broke the superhero secret identity code.
The Penguin: [to Man-Bat] What are you? And what do bats have against me, anyway?
The Joker: [upon noticing Hugo Strange] What a coinky dink! I wanted to talk about the Arkham diet. Too. Many. Nuts.
The Joker: [to Punch and Judy] You two don't count - you're not sidekicks, you're goons.
Catwoman: Hate to cut our first date short, cutie, but I like to leave a man wanting more.
The Penguin: [seeing Joker as The Batman] Joker?
The Joker: I'm The Batman!
The Penguin: You see the thing is... you're *not*!
The Joker: The eggs, Penguin, or I scramble you!
The Penguin: Are you out of your gourd? I'm in the middle of a heist! You don't see me barging in on your "Gas all of Gotham" schemes, do you? It is called professional courtesy!
The Joker: Don't make me slap you, Jack! Get it? Jack? Slap Jack?
The Joker: Sorry Batman, but Joker always laughs last.
Commissioner James Gordon: Set up a perimeter. If Mr. Quake so much as breathes, I want someone there to tell me what he had for lunch.
Batman: We both know you put yourself on ice. I'm here to bring on the thaw.
The Penguin: Please, now that all pretenses are off, call me Penguin - a flightless bird, but one with style.
The Joker: He didn't even ask about Yin-In-The-Box.
Mr. Freeze: Have an ice evening.
The Penguin: That's it, my pretties. Show me the money!
Batman: The reviews are in, Joker, your show's a flop.
Firefly: You shouldn't play with Firefly!
