Carla: I thought you might want to talk to Bryan before you went home.
Turk: How'd you know?
Carla: Who you talkin' to?
J.D.'s Narration: Unfortunately for Jake, he still had to pass muster with Turk and me. And nothing is quite as daunting as our "good guy test."
J.D.: Well, I could use a beer.
Jake: I got this round. Be right back.
J.D.: Good guy.
Turk: Great guy!
