The Keys Season 3, Episode 23

Kramer

O.K., fine, go ahead, you take the keys! But you're going to regret this. (He angrily storms out. Kramer then re-enters seconds later when he realizes he's left his girlfriend in Jerry's apartment.)

Jerry

So put 'em in a safe place.

Elaine

I will.

Jerry

Where?

Elaine

I don't know. I'll hide 'em. So, is Kramer upset?
