:smack: Ignore my above post–wrong window
Father and son having an argument, in a movie I saw about 30 years ago on TV. The father was Paul Newman, I think. No idea who played the son. But this bit of dialogue has always stuck with me:
F: “You’re a son of a bitch!”
S: “And you’re a bastard. That means we cancel each other out!”
But now that I think of it, probably my favorite line from a movie is Burgess Meredith in one of the “Grumpy Old Men” movies. I believe this happens in the outtakes at the end. He’s coming up with alternate euphemisims for Walter Matthau and, who was it, Ann-Margret?, having sex.
“He’s ridin’ the skin boat…to tuna town!!!”
The words aren’t that funny in print, but the delivery is priceless.
Reservoir Dogs:
Mr. Pink: How about if I’m Mr. Purple? That sounds good to me, I’ll be Mr. Purple.
Joe: You’re not Mr. Purple. Some guy on some other job is Mr. Purple. You’re Mr. Pink!
Mr. White: Who cares what your name is?
Mr. Pink: Yeah that’s easy for you to say, you’re Mr. White, you have a cool sounding name. All right look if it’s no big deal to be Mr. Pink, do you wanna trade?
“We train young men to drop fire on people. But their commanders won’t allow
them to write ‘fuck’ on their airplanes because it’s obscene!”

" I fear that all we have done is awaken a sleeping giant and fill it with a terrible resolve" Yamamoto, Tora Tora Tora
From the Outlaw Josie Wales: Dyin’ ain’t much of a living, boy.
And of course, from the Princess Bride: Hello, my name is Iningo Montoya, You killed my father, prepare to die.
Stalag 17: “Maybe he just wanted to steal our wirecutters, ever think of that?”
The Great Race: “There is little point in winning if one wins too easily”. (Words to live by.)
The War Wagon: Taw Jackson (John Wayne) and Lomax (Kirk Douglas) shoot a pair of bad guys simultaneously.
Taw: “Mine hit the ground first.”
Lomax (after a slight pause): “Mine was taller.”
“Wake up, time to die!”
“No matter where you go, there you are.”
Great minds think alike, and the second post no less! 
Ok how about:
“Inconceivible!” Do I need to even mention from what movie it came?
“Well, let’s not start suckin’ each other’s dicks just yet”
- Pulp Fiction
“Rambo? Rambo was a pussy.”
–Ray Tango, Tango & Cash
(To get the joke, look up who played Ray)
Also from Casablanca:
An elderly German (Jewish) couple, having vowed to speak only English:
He: Vat vatch? (What time is it?)
She: Ten vatch.
He: Such much?
From the movie that gave me my username:
“There’s no *CRYING *in baseball!”
From True Grit:
Lucky Ned Pepper: “I call that bold talk for a one-eyed fat man.”
Rooster Cogburn: “Fill your hand you sonofabitch!”
Quincy: “I don’t know any Ned Pepper. What’s he look like?”
Rooster: “Short, feisty fella. He’s got a messed-up lower lip. I shot him in it.”
Quincy: “In the lip? What was you aiming at?”
Rooster: “His upper lip.”
Looks like I picked the wrong week to stop sniffing glue
