Season 3, Episode 17: "The Boyfriend"

-Kramer, am I a chucker? -Oh, you're a chucker.

My God, I'm a chucker.

-All these years, you never told me? -It's not an easy thing to bring up.

Hey, you know, this is the first time we ever saw each other naked?

Believe me, I didn't see anything.

Oh, you didn't sneak a peek?

-No. Did you? -Yeah, I snuck a peek.

-Why? -Why not?
