The Serenity Now Season 9, Episode 3

Kramer

Simple. You let out one emotion, all the rest will come with it. It's like Endora's box.

Jerry

That was the mother on Bewitched. You mean Pandora.

Kramer

Yeah, well, she... had one, too. (George enters)

George

Jerry, can I talk to you for a second? (They enter Jerry's apartment)

Kramer

(Baseball flies at Kramer and hits him) That's it, that's it! I warned you kids. I told you not to play in front of my house. This time, I'm keepin' it. And you're not getting back your rock either!
