Walter Gordon: You know, I was under the impression that it was against departmental policy to negotiate with terrorists.
Grissom: Are you a terrorist?
Walter Gordon: Depends. [Shines flashlight in Grissom's face] Are you terrified?
Grissom: Look, I really don't want to talk to you. Where is my guy?
Walter Gordon: Oh, so he's "your guy", huh?
Grissom: Yes, he is. Where is he buried?
Walter Gordon: Are you two close?
Grissom: That's none of your business.
Walter Gordon: What does "Nick Stokes" mean to you? How do you feel when you see him in that coffin? Does your soul die every time you push that button? How do you feel knowing that there's nothing you can do to get him out of that hell? Helpless? Useless? Impotent?
[Grissom is silent]
Walter Gordon: Good. Welcome to my world. [Opens jacket, revealing Semtex strapped around him] Uh, if I were you, I'd back up a little.
[Grissom takes a step back]
[Gordon blows himself up]
Season 6

Warrick (looking at the body in the crop circle): The guy has a blindfold on.
Catherine: Pin the tail on the donkey gone wrong?

Warrick (looking at the map of registered sex offenders): Phew! That's a lot of perverts.
Nick: Get out of jail, come to Vegas.

Warrick (to Nick): How'd you shoot, man?
Nick: Rusty. They say I have a flinch.
Warrick: You and I need to go practice some, huh?
Nick: Yeah, when do we have time to do that? If we're not processing a scene or working evidence, we're in court.
Warrick: Well, when they take your piece, you'll make time.

Warrick: Alright then, lets head upstream.
Catherine: I knew you were going to say that.

Warrick: Griss, this place is crawling with press. They want a statement.
Grissom: Not now.
Warrick: Well, if you don't say anything, they're just going to fill in the blanks...
Grissom: Screw the press, 'cause for all I know, the dead body is an auto mechanic who just painted his house blue.

[About a wad of hair found in a drain. Hodges thinks it smells woodsy]
Grissom: You sniffed it?
Hodges: That disgust you?
Grissom: No. Actually it's the first thing you've ever done to impress me.

[Catherine comes in to talk to Greg, who's been reviewing video surveillance tapes for about 8 hours]
Catherine: Tell me something.
Greg: I think my eyes need band-aids.

[Greg is wearing a suit and tie and attempting to flatten out his hair for court]
Sara: Wow. Look at you, Mr. straightedge. I did not know that your hair could do that.
Greg: I look like a dork.
Sara: No, no, no. You look like a pro, which is what you are.

[looking at a university degree on the deceased's wall]
Catherine: Gang-banger girlfriend with a degree?
Nick: Sounds like a rock band.

Alien Wedding Guy: Are you two married?
Sara: (quicky) No.
Alien Wedding Guy: No? Well we're open 24 hours. There's a toll free number right on the back. (to Nick) She's gonna getcha. (Nick chuckles) [
(At a crime scene which is a night club)

Brass: So witnesses heard multiple gunshots, they think. Because it was during the blitz. You know the lights were out; sirens were going off, search lights, the whole World War II experience.
Grissom: When exactly did war became a party?

Catherine: Why is it you guys can never hit the bowl?
Detective Vartann: You know if this guy took viagra, you're lucky he hit the floor and not the ceiling.
(Examining corpse found in the desert near Area 51 and David really thinks it could be an alien)

Greg: How was it?
Warrick: Sucked. I hate lawyers. I hate court; they all need to dry up and die.

Greg: I've never seen this place with the lights on before. Kinda like seeing a one night stand for the first time in the morning. (Grissom gives him a look) Beer goggles.
Catherine: Greg mentioned to you that my stuff gets done first, right?
Chandra: Yeah, well, in my lab, I decide what gets run and when. Unless Mr. Grissom tells me otherwise.
