Warrick: I thought you said we were grabbing a beer.
Grissom (excited): We are, after this.
Warrick: Grissom, you know, this is your thing. (Warrick moves to get up, Grissom pulls him back down)
Grissom: Ah-ah-ah. Every nine years and 34 days I feel like sharing. You'll like it. It cleanses you. (Grissom reaches up and pulls down Warrick's harness, and locks it)
Warrick: Cleanses me? Whatever happened to my evaluation?
Grissom: You're sittin in it.
