Season 6, Episode 10: "The Race"

Oh, hi, Duncan. No. Four o'clock tomorrow...

...that is not going to work.

Why? I'll tell you why.

Because I choose not to run.

I'm sorry, Elaine. This shirt's too fancy.

Just because you're a Communist, you can't wear anything nice?

-You look like Trotsky. -Good.

Fine. You wanna be a Communist? Be a Communist.
