Ilsa : Play it once, Sam. For old times' sake.
Sam : [lying] I don't know what you mean, Miss Ilsa.
Ilsa : Play it, Sam. Play "As Time Goes By."
Sam : [lying] Oh, I can't remember it, Miss Ilsa. I'm a little rusty on it.
Ilsa : I'll hum it for you. Da-dy-da-dy-da-dum, da-dy-da-dee-da-dum...
[Sam begins playing]
Ilsa : Sing it, Sam.
Sam : [singing] You must remember this / A kiss is still 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-...
Rick : [rushing up] Sam, I thought I told you never to play-...
[Sees Ilsa. Sam closes the piano and rolls it away]
Rick : You know what I want to hear.
Sam : [lying] No, I don't.
Rick : You played it for her, you can play it for me!
Sam : [lying] Well, I don't think I can remember...
Rick : If she can stand it, I can! Play it!
Ilsa: Let's see ... The last time we met ...
Rick: It was 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. I remember every detail. The Germans wore grey, you wore blue.
