Jerry: Does she know?
George: No!
Jerry: How did it happen?
George: I can't say.
Jerry: Well, why can't you say it?
George: Because I promised her.
Jerry: I thought you just said she doesn't know?
George: She doesn't.
Jerry: So how can you promise her?
George: Because she asked me to.
Jerry: What is this, an Abbott and Costello routine?
