Double Indemnity (1944)
A:       Walter Neff (Fred MacMurray)
B:       Phyllis Dietrichson (Barbara Stanwyck) 

[Walter sees Phyllis for the first time.  She stands at the top of the stairs covered only in a towel because she has been sunbathing.]
A:     The insurance ran out on the 15th. I’d hate to think of your having a smashed fender… or something while you’re not… fully covered.

[Later, when they're talking about insurance]
B:       Mr. Neff, why don't you drop by tomorrow evening around 8:30?  He'll be in then. 
A:       Who?
B:       My husband.  You were anxious to talk to him, weren't you? 
A:       Yeah, I was, but I'm sort of getting over the idea... if you know what I mean. 
B:       There's a speed limit in this state, Mr. Neff.  45 miles an hour.
A:       How fast was I going, officer?
B:       I'd say around 90.
A:       Suppose you get down off your motorcycle and give me a ticket.
B:       Suppose I let you off with a warning this time.
A:       Suppose it doesn't take.
B:       Suppose I have to whack you over the knuckles.
A:       Suppose I bust out crying and put my head on your shoulder.
B:       Suppose you try putting it on my husband's shoulder.
A:       That tears it.

The "speeding" interchange made the AFI 400 nominated quotes, from which the 100 best quotes were chosen.

[Their next meeting on getting the accident insurance]
B:       He has a lot on his mind.  He doesn't seem to want to listen to anything, except maybe a baseball game on the radio.  Sometimes we sit here all evening and never say a word to each other. 
A:       Sounds pretty dull.
B:       So I just sit and knit. 
A:       Is that what you married him for? 
B:       Maybe I like the way his thumbs hold up the wool.
A:       Anytime his thumbs get tired-- Only with me around, you wouldn't have to knit. 
B:       Wouldn't I? 
A:       You bet your life you wouldn't. 

Some Like It Hot (1959)
A:      Jerry/Daphne (Jack Lemmon)
B:      Joe/Josephine (Tony Curtis)
C:      Sugar Kane Kowalczyk (Marilyn Monroe)
D:      Osgood Fielding III (Joe E. Brown)
E:      Sweet Sue (Joan Shawlee) 

[After meeting the girls for the first time]
A:       How about that talent, huh?  It's like fallin' into a tub of butter.
B:       Watch it, Daphne. 
A:       When I was a kid, Joe, I used to have a dream where I was locked up overnight in a pastry shop, and there was goodies all around.  There was jelly rolls and mocha eclairs and sponge cake and Boston cream-- 
B:       Look, stoop, listen to me.  No butter, no pastry.  We're on a diet.

[After meeting Sugar who's taking a secret drink in the bathroom of the train]
A:       Oh, boy, would I love to borrow a cup of that sugar.
B:       Look... no pastry, no butter, and no sugar! 

[By bedtime]
A:       Good night, Sugar.
C:       Good night, honey.
A:       Honey? [to Joe] Hey, she called me honey.  Ha ha!  Ooh honey.  What are you doin'?
[Joe removes the ladder to Jerry's upper berth]
B:       I just want to make sure that honey stays in her hive.  There'll be no buzzing around tonight.

[By the elevator at the Seminole-Ritz Hotel]
D:       So this year, when The George White Scandals opened, she packed me off to Florida.  Right now she thinks I'm out there on my yacht... deep-sea fishing.
A:       Well, pull in your reel, Mr. Fielding.  You're barking up the wrong fish. 

[In their room at the Seminole-Ritz Hotel]
A:       Dirty old man!
B:       What happened?
A:       I just got pinched in the elevator. 
B:       Now you know how the other half lives.
A:       [looks in the mirror] Look at that, I'm not even pretty.
B:       They don't care, just so long as you're wearing a skirt.  It's like waving a red flag in front of a bull.  
A:       Really?  Well, I'm sick of being the flag!  I want to be a bull again!

[At the bandstand with Sweet Sue signing off]
E:       Well, that's it for tonight, folks.  This is Sweet Sue saying good night, reminding all you daddies out there that every girl in my band is a virtuoso, and I intend to keep it that way.

[At the yacht]
B:       It's like smoking without inhaling.
C:       So inhale!

[At the yacht, later]
B:       I got a funny sensation in my toes, like someone was barbecuing them over a slow flame.
C:       Let's throw another log on the fire.

The Major and the Minor (1942)
A:      Albert Osborne (Robert Benchley)

Stalag 17 (1953)

B:      Sgt. Johann Schulz (Sig Ruman)
C:      Harry Shapiro (Harvey Lembeck)

A:      Hey Schulz, as long as you're gonna move somebody in, how about a couple of them Russian broads?
B:      Russian women prisoners?
C:      Jawohl.
B:      Some are not bad at all.
A:      Ja.  Just get us a couple with beautiful glockenspiels.

The Apartment (1960)
A:      Al Kirkeby (David Lewis) 

A:      That Kubelik - boy!  Would I like to get her on a slow elevator to China. 

One, Two, Three (1961)
A:     C. R. MacNamara (James Cagney)
B:     Fräulein Ingeborg (Liselotte Pulver)
C:     Phyllis MacNamara (Arlene Francis)

A:     Guten morgen, MacNamara.
B:     And a guten morgen to you, Fraulein Ingeborg.
A:     It is not Frow-line.  It is Froy-line with an umlaut.
B:     [whistles] I'll say.  Monthly report.
[MacNamara dictates a letter.]
A:     [pauses from the official letter] Next, what did you do over the weekend?
B:     Nothing.  I stayed home waiting for you.
A:     I tried to make it, believe me.  I just couldn't get away. [telephone buzzes] But there's good news tonight.
[MacNamara talks to his wife Phyllis on the phone in the presence of the secretary.]
A:     Like I said, good news.
B:     Your wife.  She's making a trip?
A:     Is she ever.  Going on vacation mit die kinder.
B:     Ach so.
A:     So tonight, we'll split a schnitzel and start on the German lessons again.
B:     We should.  You must be getting rusty.
A:     We'll just have to work at it twice as hard from now on.  Das ist gut?
B:     Sehr gut.
A:     And the first thing we're gonna do is brush up on the umlaut.
B:     Das ist wunderbar.
A:     Mmm.  Like all the lilacs in lower Bavaria.

[At the airport, the MacNamaras come to pick up Scarlett, the daughter of MacNamara's boss]
C:     [very annoyed] Here.  You give her the flowers.
A:     Oh, cut it out, Phyllis!  What was I going to do?  The boss asked me to look after his only daughter.  I can't disappoint him.
C:     Well, what about your only children and your only wife?  We were all packed and ready to go.  Don't you think we were disappointed? 
A:     Believe me, Phyllis, everybody's disappointed.  We'll just have to put things off a couple of weeks.  The roller skates and the snorkel and the umlaut.
C:     The what?

[The office.  After two months.]
A:      Guten morgen, Fraulein Ingeborg.
B:      Guten morgen.
A:      [smells her] Mmm, like freshly baked pumpernickel.
B:      Here's your mail, here's your Wall Street Journal, and here is my resignation.
A:      Resignation?  What are you talking about?
B:      Now, you do not work me overtime anymore.   You do not take advantage of me on weekends.   You have lost all interest in the... umlaut, so obviously, my services are no longer required here.

The Seven Year Itch (1955)
A:      The Girl (Marilyn Monroe)
B:      Richard Sherman (Tom Ewell)

A:      Hi!  It's me.  Don't you remember? The tomato from upstairs. [gesturing from up to down, the trajectory of the tomato plant pot]
B:      Oh, of course!  The tomato.  Come in, please.  Come in. 

A tomato plant in a pot fell off from the upper balcony of the Kaufman's apartment where the girl is staying on a summer sublet.      

Five Graves to Cairo (1943)
A:       Field Marshal Erwin Rommel (Erich von Stroheim)
B:       Mouche (Anne Baxter) 

B:       If there's anything I can... do. 
A:       You're suggesting some sort of bargain?  This is a familiar scene, reminiscent of bad melodrama, although usually it is not the brother for whose life the heroine comes to plead, it is the lover.  The time is midnight.  Place: the tent of the conquering general.  Blushingly the lady makes her proposal, and gallantly the general grants her wish.  Later, the lady very stupidly takes poison.  In one Italian opera, the two even go so far as to sing a duet! [calls] Schwegler!
B:       If I had any tears left, maybe you'd listen. 
A:       There will be no duet today.
