Here's looking at you, kid. Ranked #5 in the "100 Movie Quotes" list

I'm only a poor corrupt official.

[about Ugarte] I'm making out the report now. We haven't quite decided whether he committed suicide or died trying to escape.

You seem to think of me as just the leader of a cause, but I am also a human being.

Renault: My dear Ricky, I suspect that under that cynical shell, you're at heart a sentimentalist...Oh, laugh if you will, but I happen to be familiar with your record. Let me point out just two items. In 1935, you ran guns to Ethiopia. In 1936, you fought in Spain on the Loyalists' side.
Rick: And got well paid for it on both occasions.
Renault: The winning side would have paid you much better.
Rick: Maybe.

Laszlo: I'm sure you'll excuse me if I'm not gracious. But you see Major Strasser, I'm a Czechoslovakian.
Strasser: You were a Czechoslovakian. Now you are a subject of the German Reich.
Laszlo: I've never accepted that privilege and I'm now on French soil.

Sam: I never expected to see you again...A lot of water under the bridge.
Ilsa: Play some of the old songs, Sam... Where is Rick?
Sam: I don't know. I ain't seen him all night.
Ilsa: When will he be back?
Sam: Not tonight no more. He ain't comin'...He went home.
Ilsa: Does he always leave so early?
Sam: Oh, he never..., well, he's got a girl up at the Blue Parrot. He goes up there all the time.
Ilsa: You used to be a much better liar, Sam.
Sam: Leave him alone, Miss Ilsa. You're bad luck to him.
Ilsa: Play it once, Sam, for old times' sake.
Sam: I don't know what you mean, Miss Ilsa.
Ilsa: [whispered] Play it, Sam. Play As Time Goes By. (#28 in the AFI's list of the top 100 movie quotations)
Sam: Why, I can't remember it, Miss Ilsa. I'm a little rusty on it.
Ilsa: I'll hum it for you. [Ilsa hums two bars. Sam starts to play] Sing it, Sam.
Sam: [singing] You must remember this
A kiss is just a kiss
A sigh is just a sigh
The fundamental things apply
As time goes by.
And when two lovers woo
They still say, 'I love you'
On that you can rely ,
No matter what the future brings
As Time Goes By. Lyrics and Music by Herman Hupfeld (1931)

Rick: [rushing in] Sam, I thought I told you never to play... [stares at Ilsa]

Renault: I can't get over you two. She was asking about you earlier, Rick, in a way that made me extremely jealous.
Ilsa: [to Rick] I wasn't sure you were the same. Let's see, the last time we met was -
Rick: La Belle Aurore.
Ilsa: How nice. You remembered. But of course, that was the day the Germans marched into Paris.
Rick: Not an easy day to forget.
Ilsa: No.
Rick: I remember every detail. The Germans wore gray. You wore blue.
Ilsa: Yes. I put that dress away. When the Germans march out, I'll wear it again.
Renault: Ricky, you're becoming quite human.

Rick: Say, why don't we get married in Marseilles?
Ilsa: That's too far ahead to plan.
...
Ilsa: I love you so much. And I hate this war so much. Oh, it's a crazy world. Anything can happen. If you shouldn't get away, I mean, if something should keep us apart, wherever they put you and wherever I'll be, I want you to know that...kiss me. Kiss me as if it were the last time.

Rick: How can you close me up? On what grounds?
Renault: I'm shocked, shocked to find that there is gambling going on here!
Croupier: Your winnings, sir.
Renault: Oh, thank you very much.

Rick: And remember, this gun is pointed right at your heart.
Renault: That is my least vulnerable spot.

Renault: It might be a good idea for you to disappear from Casablanca for a while. There's a Free French garrison over at Brazzaville. I could be induced to arrange a passage.
Rick: My letter of transit? I could use a trip. But it doesn't make any difference about our bet. You still owe me ten thousand francs.
Renault: And that ten thousand francs should pay our expenses.
Rick: Our expenses? Louis, I think this is the beginning of a beautiful friendship.

I stick my neck out for nobody.
