The Chinese Woman Season 6, Episode 4

Elaine

I thought you wore silk underwear.

Kramer

No, no, n--Well, you know, I wore 'em for about a month but I couldn't stick with it. No, I need the secure packaging of Jockeys. (he's serious. Then he makes a hand gesture of grabbing up) My boys need a house!

Elaine

(not charmed) That's nice. Listen, Kramer, you know, if you ever want to have kids you shouldn't wear briefs. Boxers are much better for your sperm count.

Kramer

Sperm count? Well how many ssssperm should I have?

Elaine

A lot!
