Commissioner Ellen Yindel: "It's not suicide, lieutenant. The girl with him is from Kyle Escort. She's been drugged. Shut the joint down... And pick up Selina Kyle."
O'Halloran: "Yes, ma'am. Thank you, ma'am."
*O'Halloran goes away*
Another cop coming from another direction: "Commissioner... O'Halloran, ma'am, sixth precint."
*Yindel looks at O'Halloran with jaw dropped and realizes she just talked with Batman*
Yindel: "STOP THAT MAN!"
From the animated movie, this Joker line. Doubly so if you think he was serious and wasn't joking.
Wolper: He's a victim of Batman's psychotic obsession.
Joker: (looks confused) ...I thought I was Batman's psychotic obsession.
The Animated Movie also casts the talk show host (in the comic a David Letterman look-alike who told crummy jokes) with Conan O'Brien. The scene now contains so much dark, absurdly-awkward humor that you just know Conan had to have a hand in re-writing it.
Joker: I want people to get me. Conan: Alright then. Joker:(Slowly drinks out of Conan's mug) That's why I'm gonna kill everyone in this room. (Beat) Conan: Oooookay. That's a little more insight than we had in mind....
