Chief Dwayne: Now you listen to me, mister. I don't know who the hell you think you are or what you're doing, but you just destroyed a building! Now we do not want your help, is that clear? We don't want your help. I've got a 100 people down here and they are covered with glass!
John McClane: Glass? Who gives a shit about glass?
John McClane: So that's is what this is about, Hans? A fucking robbery?
Hans Gruber: Put down the gun.
John McClane: Why'd you have to nuke the whole building, Hans?
Hans Gruber: Well, when you steal $600, you can just disappear. When you steal 600 million, they will find you, unless they think you're already dead.
Hans Gruber: Mr. Mystery Guest? Are you still there?
John McClane: Yeah, I'm still here. Unless you wanna open the front door for me.
Hans Gruber: Uh, no, I'm afraid not. But, you have me at a loss. You know my name but who are you? Just another American who saw too many movies as a child? Another orphan of a bankrupt culture who thinks he's John Wayne? Rambo? Marshal Dillon?
John McClane: Was always kinda partial to Roy Rogers actually. I really like those sequined shirts.
