CSI: Crime Scene Investigation Season 4 Episode 18

(After finding a body in the ground)
Warrick: What do you think, Grissom? Been down here at least 3 years? (Grissom sniffs, around it)
Grissom: It's probably more than 3 years.
Brass: You're kiddin' me, right?
Grissom: Rule of thumb is if the skull smells bad it's usually under 3 years. But this one smells like dirt.

(A little after he was attacked by a suspect)
Catherine: You okay?
Grissom: I'm fine. (she turns his head to the right to see his neck injury)
Catherine: Nasty. Kinda looks like a hickey. (Grissom makes a face and pushes her hand away from his face) You wanna tell me what got this party started?
Grissom: I scraped his nails.
Catherine: That's it?

Brass: It's not as bad as it looks.
Sheriff Atwater: It never looks good when a suspect dies in custody.
Brass: What are you saying, Rory? You'd rather it be one of us?
Sheriff Atwater: No, that's not what I'm saying. If I was here, I'd have been in there with you, you know that. I assume we're going to come out looking like the bad guy again.

Brass (to Walter): That stare doesn't work on me. But save it, cause they're gonna love it in prison.

Doc Robbins: How many teeth did you find at the crime scene?
Grissom: Two.
Doc Robbins: He's missing six. I found one in the back of his mouth. He probably swallowed the other three. I'll check his stomach.

Brass: Our vic Tony just checked into the hotel. Didn't even unpack his bags.
Grissom: He made enemies fast.

Brass: (checking the beaten victim's driver's license) Tony Sciarra from Philadelphia.
Grissom: So much for brotherly love.

Grissom: 'The evil men do lives after them. The good is often interred with their bones'.
Warrick: Shakespeare?
Grissom: Julius Caesar.
