The Serenity Now Season 9, Episode 3

Jerry

What happened to you, pal?

Kramer

Joey Zanfino and some of the neighborhood kids. They ambushed me with a box of 'Grade A's.

Jerry

Are you all right?

Kramer

Oh, no. I'm fine. Serenity now. Serenity now. Serenity now.

Jerry

So, you're using Frank's relaxation method?
