Warrick: How is it that you know so much about poker?
Grissom: It's how I financed my first body farm in college.
Warrick: You're kidding. Wow. I'm impressed and the fact that you sat at a table with actual living beings.
Grissom: Well ... poker's not a game of interaction. It's a game of observation. I used to study people. And then I guess I, uh ... got bored. Now I study evidence.
Warrick: What I don't get is it's not like we've never talked about gambling before. How come you never mention it?
Grissom: Same reason a good player hides his "tells."
Warrick: He doesn't want to be exposed.
