Kramer: Hey, Jerry. What is this? Lady Gillette? What's going on? [barges into the bathroom]
Jerry: What? Can't I get a moment's peace?
Kramer: What are you doing to yourself?
Jerry: I can't stop. Alex thinks I'm naturally hairless.
Kramer: You can't keep this up. Don't you know what's going to happen? Every time you shave it, it's going to come in thicker and fuller and darker.
Jerry: Oh, that's an old wives tale.
Kramer: Is it? Look at this. [off-screen] Look at it! Look at it! And it's all me. [returns clothed] I shaved there when I was a lifeguard.
Jerry: Oh, come on. That's genetic. That's not going to happen to me.
Kramer: Won't it? Or has it already started to happen?
