Sumner: Listen, I must dash. I'll be back in ten minutes. Excuse me, what's your name?
Sam: Sam.
Sumner: Listen, Sam, old man, I have an errand to run. Now, Diane is going to stay here. I'd appreciate it if you would keep an eye on her.
Sam: For you, Sumner, old man, I'll keep both my eyes on her.
Diane: Sumner, am I stupid to let you go see a woman you were once in love with?
Sumner: Oh, my, darling, I'm leaving you alone in a bar. Which one of us is the stupider?
Sam: Too close to call.
