The Chinese Woman Season 6, Episode 4

Elaine

You got a comfort problem there?

Kramer

No, I think these Jockeys shrunk.

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.
