[turns around to see a man]Who the hell are you?
[Grissom goes for his gun]Don't bother.
[steps into the light]You can call me... Joker. And as you can see, I'm a lot happier.
[laughs, and then proceeds to kill Grissom]
[talking to a gargoyle]What are you laughin' at?
[reciting his poem to Vicki]I'm only laughing on the outside / My smile is just skin deep / If you could see inside I'm really crying / You might join me for a weep.
[Bob hands him a gun, Joker shoots him]I'm gonna need a minute or two alone, boys.
[shakes hands with the Joker and begins to get electrocuted]:[Shakes hands with The Joker and starts to get electrocuted]
[starts to laugh hysterically][singing] Oh, there'll be a hot time in the old town tonight.
[He begins to laugh again and mops sweat from his brow, exposing a patch of chalk-white flesh]
[laughs]Shall we dance?
[Batman punches him]
[looks surprised]Grease 'em now? Well, OK. You are a vicious bastard Rotelli, and, uh, I'm glad you're dead!
[imitates Grisson]Remember... you... are my number one... guy!
[examining Vicki's work]Crap... crap... crap... crap...
[sees pictures of war victims]Ah! Now that's good work! The skulls... the bodies... you give it all such a glow! I don't know if it's art, but I like it!
[Walks towards the fireplace]Couldn't keep it straight up here.
[Points to his head]He was the kind of guy who couldn't hear the train until it was 2 feet from him.
[Smiles and nods his head]
[Shakes his head]
[grabs a poker and smashes a vase]LIGHTS OUT! Now you wanna get nuts? Come on! Let's get nuts.
[shows up unexpectedly at Vicki's place]Miss me? Nice place you've got here. Lots of space. Uh, Vicki, we've really got to have a talk. I'm very upset. We were having dinner. I was a man doing well with a beautiful woman. And without so much as an apology, you ran off with that sideshow phony.
[sees Bruce Wayne enter the room]Well, Miss Vale, another rooster in the henhouse.
[after shooting Bruce Wayne]Why is it everytime I come for you somebody always gets in the way?
