Seinfeld1989

[in Jerry's apartment]

Jerry:
Why did you have to open your big mouth?

Cosmo Kramer:
What?

Jerry:
George doesn't need to hear that his girlfriend looks like me. Neither do I, for that matter. First the Sally Weaver thing, now this.

Cosmo Kramer:
You're just mad because you're having a bad day.

Jerry:
Yes. Because of you.

Cosmo Kramer:
Well, in that case I think one of us should leave.

[Kramer and Jerry stare at each other and don't move]
