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. My boys need a house!
ELAINE: 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 sperm should I have?
ELAINE: A lot!
Just gonna look that up! lol!
