Sponge Worthy - The entire episode. George refusing to use condoms because there is too much pressure to get the package open in time. And this...
ELAINE: Yeah, it was, but then I just couldn't decide if he was really sponge-worthy.
JERRY: Sponge-worthy?
ELAINE: Yeah, Jerry, I have to conserve these sponges.
JERRY: But you like this guy, isn't that what the sponges are for?
ELAINE: Yes, yes - before they went off the market. I mean, now I've got to re-evaluate my whole screening process. I can't afford to waste any of 'em.
Later...
ELAINE: So, you think you're sponge-worthy?
BILLY: Yes, I think I'm sponge-worthy. I think I'm very sponge-worthy.
ELAINE: Run down your case for me again...?
BILLY: Well, we've gone out several times, we obviously have a good rapport. I own a very profitable electronics distributing firm. I eat well. I exercise. Blood tests - immaculate. And if I can speak frankly, I'm actually quite good at it.
ELAINE: You going to do something about your sideburns?
BILLY: Yeah, I told you...I'm going to trim my sideburns.
ELAINE: And the bathroom in your apartment?
BILLY: Cleaned it this morning.
ELAINE: The sink, the tub, everything got cleaned?
BILLY: Everything, yeah. It's spotless.
ELAINE: Alright, let's go. <They head for the bedroom.>
