Thanks, tracer. I coulda sworn it was from the first one. Regardless, it’s a hilarious scene !
My Favorite Year
A drunken Allen Swann: I’ll hold the rope taut, and you can just shimmy down.
Benji Stone: I’m not shimmying down anything. It’s too dangerous!
AS: Nonsense. It worked perfectly well in “A Slight Case of Divorce”.
BS: That was a movie. This is real life.
AS: What is the difference?
BS: I think I’m going to be unwell.
AS: Ladies are unwell, Stone. Gentlemen vomit.
AS: Damn you! I’m not an actor, I’m a movie star!
Sy Benson: He’s plastered!
Allen Swann: So are some of the finest erections in Europe.
Belle Caroca, to Allen Swann: Welcome to our humble chapeau.
Benji Stone: Two years at the Sorbonne, she still gets it wrong.
Stan “King” Kaiser: What are they serving in the cafeteria today, Leo? Are they serving tongue? Twice they served tongue on show day and twice the opening sketch died. No tongue on show day, Leo, no tongue. Tongue? … Death!
I’m going REAL obscure (I think) on you guys, but I’ve seen The Dancing Outlaw 100 +/- times. It a PBS documentary done on some folks living in (very) rural West Virginia. The protagonist is a dancer (pronounced DAIN-ser) named Jesco who must choose between his Elvis collection and fulfilling his murdered father’s legacy by tap dancing (see above pronounciation) while reconciling the differences between he, his family, and his on again/off again wife. To quote:
I have an mpg of this one, if you don’t believe me, I’ll mail it to you.
Jesco (narrating): “I took the butcher knife and put it up to her neck and I said if you wanna live to see tomorrie, you better start fryin’ them eggs (aygs) a lil bit better’n what choo been fryin’ em, I’m tired (tared) of eatin’ sloppy, slimy eggs (aigs).”
Jesco (narrating): “And one buckshot got me in the neck, and I said oh my god I’m shot!. Really! Seriously!”
Jesco (narrating): “…and I took me a whiff of that gasoline (hand to mouth and makes sniffing noise) and buddy I was it. I was superman. I felt I could stand in front of a coal train and stop it (motions how he could do so).”
Jesco (narrating): “If it wasn’t for this Elvis collection, I’d probably be dead by now”
I could do the whole movie, but I’ll spare you 
I believe that the most quotable film of all time must be The Godfather (parts I and II). For some reason I love to quote Michael’s dialogues with Fredo (e.g., “Don’t ever take sides with anyone against the family”; “I know it was you, Fredo! You broke my heart!”).
I’m surprised nobody’s mentioned Goodfellas yet, even if it’s only for Tommy’s (Joe Pesci’s character) scene: “What do you mean, I’m funny…?”
My personal favorite for quoting, however, is Blue Velvet. All of Frank Booth’s lines are… memorable, to say the least.

My Favorite is
Women to Allen Swan who has just entered the ladies restroom.
Hey, this is for ladies only!
(Allen Swan unzips his fly) And so is this madam, but every now and then I have to run a little water through it.
Not to nitpick, but…
<nitpick>
Venkman: “Come in, Ray.”
Stantz: “Venkman! IsawitIsawitIsawit!”
Venkman: “It’s right here, Ray. It’s looking at me.”
Stantz: “He’s an ugly little spud, isn’t he?”
Venkman: “I think he can hear you, Ray.”
Stantz: “Don’t move. He won’t hurt you.”
Slimer: “Ouaghouagh…”
Venkman: “Aaaaaaaaaaahhhaaaaaaaah!”
Stantz: Venkman? Venkman?! Pete?!"
<running>
Stantz: “Venkman! What happened? Are you OK?”
Venkman (spitting): “He slimed me.”
</nitpick>
I watched Ghostbusters once or twice…every day for a year or so. 
Other things watched far too many times include:
The Dark Crystal (I’ve had at least one copy at all times since before the advent of VCRs.)
“The Trouble with Tribbles” (Not a movie, but the object of obsessive watching nonetheless. There was a time when I could start the show, turn down the volume, sit with my back to the TV, and lip-synch every line of dialogue. Complete with accents and expressions. I was a weird kid.)
The Jerk: “This guy really hates cans!!!”
Eddie Izzard: Dress To Kill: “Sir, the rebels are here!”
“My god man! Do they want tea?”
“No, I think they’re after something else. I’m not sure what, but they brought a flag.”
“Germany would build an empire; ‘eins, zwei, eins, zwei, build an empire, build an empire’. Then they would celebrate with a world war, and lose the whole fucking empire.”
“And Hitler was a painter, so at one point he must have been ‘Can’t get the fucking trees right… DAMN! I WILL KILL EVERYONE!!!’”
Dave Chapelle: Killing Them Softly: “Dave… I’m gonna race 'em.”
