Kelso: [doorbell rings] Oh, kick back. I'll get it.
Red: No, it's the paperboy. [ringing continues]
Kelso: Well, Mr. Forman, you have to answer the door.
Red: Look, I forgot to pay him for the last couple of weeks and I didn't pick up any cash, so, just ignore him.
Kelso: Red, I don't think you understand, okay? I- I can't let a doorbell go unanswered. [ringing continues]
Red: Don't answer the damn door.
Kelso: I gotta.
Red: Don't.
Kelso: But I gotta.
Red: All right. Fine. You pay him, kettlehead. [exits]
