It's a Wonderful Life (1946)
Sheldon Leonard: Nick
Nick : [ringing the cash register repeatedly] Get me. I'm givin' out wings!
Nick : Hey look, mister. We serve hard drinks in here for men who want to get drunk fast, and we don't need any characters around to give the joint "atmosphere". Is that clear, or do I have to slip you my left for a convincer?
George Bailey : [intervening] Nick, hold on. Just give him the same as mine. He's no trouble.
Nick : Okay.
[Nick walks away to tend to the bar]
George Bailey : [to Clarence] What's the matter with him? I never saw Nick act like that before.
Clarence : You'll see a lot of strange things from now on.
Nick : [slamming a bottle on the bar] That's it! Out you two pixies go... through the door, or out the window!
George Bailey : Hold on, Nick! What's wrong?
Nick : That's another thing. Where do you come off calling me Nick?
George Bailey : Well... Nick, that's your name. Isn't it?
Nick : What does that have to do with anything? I don't know you from Adam's off Ox.
George Bailey : [to a derelict Mr. Gower] Mr. Gower! This is George Bailey! Don't you know me?
Mr. Emil Gower : No... No...
Nick : [to his bouncers] Throw 'em out, throw 'em out!
George Bailey : Mr. Gower! Hey, what is...? Hey, Nick! Nick! Isn't that Mr. Gower, the druggist?
Nick : You know, that's another reason for me not to like you. That rum-head spent twenty years in jail for poisoning a kid. If you know him, you must be a jailbird yourself.
