Batman: Under the Red Hood/Funny

"Black Mask: We're going on offense. Rough up HIS business. Something BIG, something LOUD! When he shows up to shut us down, have a party waiting for him! And when I say party, I actually mean A WHOLE LOT OF PEOPLE WHO ARE GONNA KILL HIM! Ms. Li: (deadpan) I figured. Black Mask: Just Being Clear."
 * Sweet Jesus, where to begin? The Joker naturally is hysterical but it's Black Mask that manages to upstage the Joker in hilarity. Every scene with him in it is either him vigorously eating the scenery, him punching his henchmen or him making hilarious faces to bad news. He's pretty much J. Jonah Jameson if he were a crime boss. It also helps that his female assistant never reacts to any of his outbursts.

"Joker: Gotta give the kid points! He came all the way Back From the Dead to make this shindig happen. So; who's got a camera? Ooh, ooh, get one of me and the kid, first...then you and me, then the three of us and then one with the crowbar! : You keep your mouth shut, clown. Or I'll put one in your lap first. Joker: (plaintively) Party pooper. No cake for you."
 * This one with Joker.

"(Red Hood waves to Black Mask before taking aim) Black Mask: Oh, hell. (ducks out of screen and runs as fast as he can to the exit)
 * The part where Red Hood is aiming a rocket launcher at Black Mask from an adjacent building and Black Mask spots him.

Red Hood: Wow, he sure can move when he really wants to."

"Joker: (pointing a gun at Black Mask) I'm going to need something to wear. And a very big truck. Black Mask: Sure. Anything else? Joker: I'll need some guys. (Beat) Not these guys, because, well, they're kinda dead."
 * Just after the Joker kills Black Mask's Mooks, there's this Dark Humor-filled exchange:


 * Nightwing has several. Of particular note was the bit where he stops to take a sip of tea during a conversation with Bruce. When he looks up, Bruce is in the Batmobile, with the engine running. Nightwing puts his cup down and starts towards it, saying "Could you just once say 'Let's get in the car'?! Is that too hard?"
 * *Batman grabs a harpoon gun from Nightwing and runs towards the edge of the building* "So should I...? Do you want me to...? Okay, I'll just... take care of this, then."
