Harley Quinn: [in the Batmobile, after picking a fight with Bobby Leibowitz] Waited ten years to get that...
[Batman keeps silencing her with his finger]
Harley Quinn: I was just... But... He...
Batman: [pulls over] Pull a stupid stunt like that again, and I'm dumping you off at the nearest police station.
Harley Quinn: [very rebelliously] Oh, big whoop. "You're living under my roof. You play by my rules." Is that it? Newsflash, gruesome. You ain't my dad!
Batman: [appalled that Harley has just dared to talk back to him] This isn't a game, Harley. I need you to stay focused on the job at hand.
Harley Quinn: [still oblivious] Focus-schmocus. You know, I'm starting to rethink this whole deal. Here I am, helping you guys out, pro bono, I might add, and you got to go and get all mega control-freaky on me. "Do this. Don't do that! Sit up straight. Brush after every meal. Don't bite your toenails. Keep your knees together when you're wearing a dress."
Batman: [fed up with Harley's insults] Harley! There are lives at stake.
Harley Quinn: [resigned] Oh, my God! Yeah, yeah, the whole world's gonna plotz. I get it. I get it. You think I'm just some dizzy airhead that don't know nothin'. Do you know what I am?
Batman: My punishment for dropping out of med school.
