KRAMER: Jerry. Did ya ever have your sperm count checked?
JERRY: No, why should I? I wear boxers.
KRAMER: You ever get a woman pregnant?
JERRY: I’m sorry, Kramer. Those records are permanently sealed..
KRAMER: What would you say if I told you, “I never impregnated a woman”?
JERRY: Really? You never slipped one past the goalie in all these years??.. Boy, I’m surprised. You’ve slept with a lot of women, I—
KRAMER: A lot of ‘em! Do you think maybe I’m.. Depleted??!!
JERRY: Well, I’m sure you’re not.. Totally Depleted.
KRAMER: Well, but what if I am? I’m the last male Kramer! We’re facing extinction!
JERRY: Well, go to a fertility clinic. Have your sperm count checked.
KRAMER: Yeah, but then I’d have to.. well, you know.. into a cup? In the middle of the day??
ELAINE: Does that conflict with your regular schedule?
