Man... had to go and steel my resolve... but no tequila. Many of my favs have been mentioned, such as:
Any line from Raising Arizona (or any Cohen Bros. film):
Herbert I. ("H.I.") McDonough: "I'll be takin' these Huggies here, and whatever cash you got in the register... And could you hurry it up, I'm kinda in Dutch with the wife."
H.I.: "Even though this beautiful child looked as fertile as the Tennessee Valley, as the doc explained it, her insides were a rocky place, where my seed could find no purchase..."
H.I.: "Biology, and the prejudices of others, conspired to keep us childless..."
Any line from Tin Men (Levinson):
Tully: I got his name right here, Polish name, Bobowski, Bill Bobowski, son of a *****...
Other guy: Hey I know that guy...
Tully: You know the guy??
Other guy: You know the guy, they call 'im BB, Gibraltar Siding, hangs out with Bagel, Cheese, Carlie Binelli... Gibraltar Siding, you know the guy..."
Tully: "I don't KNOW the Guy...
Other guy: You know the guy, we sarw im the other night at the club, he's a great danca, he does a great merengue.
Tully: I don't want to date 'im... I'm just sayin I don't know the guy, all right?
Other guy: You know the guy... he's a great danca...
Sam: I think that he's indicating that he doesn't know the guy.
Any line from The Princess Bride (Reiner):
Inigo: "Inconceivable? I don't think that word means what you think it means."
Of course, Paula (??) already got "Hello, my name is Inigo Montoya, you killed my father, prepare to die..."
Midnight Run (director??):
Grodin: "When we know each other? When are we going to know each other...? You ever (screwed) a chicken, Jack?"
DeNiro: "I don' know, I saw a couple back there I mighta taken a shot at..."
That's all I got at the moment, but if anyone has others/better, I'll try to follow up.
Thanks SJ, goin to check other forums (fora?) now...
