Quote from Kramer in The Serenity Now
Jerry: What happened here, Kramer? Kramer: [mumbling] Serenity now. Serenity now. Jerry: Kramer! Kramer: Geez! Jerry, I didn't here you come in. Yeah, the children, they've done some redecorating. Serenity now. Serenity now. Jerry: You don't look well. Kramer: Oh. Well, that's odd, 'cause I feel perfectly at peace with the world- [agitates at nothing] Eggs, you. Jerry: Oh, I'm sorry. Look at me, I stepped on your last rose. Kramer: Jerry, come on. Don't get upset about it. There's always next spring. Now will you excuse me for a moment. [goes into his apartment] Serenity now!
