W1: Office Space.
(love that movie)
Beneath the Planet of the Apes.
JB1: “Your husband isn’t dead, lady. He’s hiding” - Is it The Ref?
SKEE 2: Neither the movie nor the quote was very obscure, I see. You got me.
Sublight, ya nailed it.
Baker: Yeah, I knew that. I thought Aura had a line of dialogue between Dale’s two lines, though. I haven’t seen it recently enough, I guess. (Any excuse to dig that out of the collection and watch it again, I know, I know.) 
ShibbOleth: Nope. Don’t know if I’ve ever actually seen The Hustler, start to finish, though. Thinking of a different flick here.
SKEE 5: Do you guys have sour balls? Yeah? Bet you don’t get many blow jobs.
[sub]This one’s mildly obscure because it’s not in every version of the flick.[/sub]
SKEE 6: How’s about you and you girlfriend race me over there?
SKEE 7: There are thousands of children starving in the world, and you’re walking around with a sombrero full of peanuts. I hope you’re happy.
SKEE 8: I could do this all day long… I’m talkin’ all day long.
NCUN1: The feather was just a gag!
(For you older folk out there.)
OK, it’s not really obscure, but I like it sooooo much and the “favorite lines” thread is kinda stale.
DataZak, yep, The Ref is is.
SKEE5: Is that Clerks, maybe?
SKEE7: Meatballs
A couple more…
JB4: “Boy, that guy sure had sharp teeth.”
JB5: “The laws of gravity no longer apply, right?”
Tremors. How can you not love this movie?
PG1: “I have a question for you, Lord. Why did you make so many suckers?”
You’re warm. And it’s four out of five. Don’t argue with me, young man. 
(although there are two dubbed versions of the film that are used by networks to eliminate the naughty language, so they might have changed it when they dubbed it).
Both of mine were guessed correctly -
K1 = Airplane
K2 = Waking Ned Devine
I forget who got them, but you know who you are.
li’l Dickie Dirtz and Robot Arm…correct!
MK1 was tough, IMO. Well done!
That was Cheech, in “Up in Smoke” (he thinks, wrongly, that Chong just scored with two chicks in the van).
**
To re-post one of mine, and add a few more:
AST1: “No kidding, you’re a Jew? Well then… why aren’t you SMART?”
AST2: “Are you gonna do something, or just stand there and bleed?”
AST3: “Double the lad’s bet for me, you toad!”
AST4: " I don’t know if I was interested so much in the science as I was in the slime that goes along with it. Snakes and frogs. "
The line is Clint Eastwood, but I can’t name the film. I think it’s Unforgiven, though.
AST3: “Double the lad’s bet for me, you toad!”
I believe that’s My Favorite Year – Peter O’Toole, Mark Linn-Baker. Good movie.
I could be wrong … but it’s still a good movie.
Well, since I answered one, I’ll post one:
Sub1: “I never strangled a chicken in my life!”
Fargo?
GB1: “Don’t call me stupid”
I think that’s “Back To The Future” but I’m probably wrong.
Zap 1: “Hey kid, you know your last name’s an adverb?”
Zap 2: “Still don’t get the big brain bit, do ya?”
GB1: A Fish Called Wanda.
I’ll add one from the same movie for my D3 since no one got it:
“Golf, Bravo, Bravo, Romeo, Tango.”
Rounders
Would you like a pretzel? I baked them myself!
Baseketball.
greatZebu, bingo on Rounders, despite my typo.
Zap 1: “Hey kid, you know your last name’s an adverb?”
Zap 2: “Still don’t get the big brain bit, do ya?”
Zap1: Johnny Dangerously
Zap2: Defending Your Life
