Dooley Wilson: Sam
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]
Sam : Let's get outta here.
Rick : No Sam, I'm waiting for a lady.
Sam : Please boss, let's go. Ain't nothing but trouble for you here.
Rick : She's coming back. I know she's coming back.
Sam : We'll take the car. We'll drive all night. We'll get drunk. We'll go fishing and stay away until she's gone.
Rick : Shut up and go home, will ya?
Sam : No sir, I'm staying right here.
