Grissom: I'm not going with you.
Catherine: What do you mean?
Grissom: I'm scheduled for surgery at Desert Palm.
Catherine:: Surgery? [She walks over to him] Your hearing?
Grissom: [nods] Yep.
Catherine: I'm sorry.
Grissom: I'm not. Has to be done.
Catherine: What can I do?
Grissom: Nothin', I'm fine. Take care of the case.
Catherine: Wha--ah, that's it?
Grissom: That's it. Um... good luck.
Season 4

Grissom: I'm that obvious, huh?
Lady Heather: Only because you try not to be.

Grissom: If just one person had stopped and taken the time to look at the guy to listen to him, to figure out what was wrong with him it might not have happened. It took five people to kill him. It would have only taken one person to save his life.

Grissom: If latex rubber and cooking spray went on a blind date, how would the night end?
Charlotte: A lot better than ours did.
Grissom: I know, Pink Floyd's not your thing.
Charlotte: I have on cowboy boots. I work in a lab. What makes you think "Dark Side of the Moon" synched to the Wizard of Oz is going to warm my damn barn?
Grissom: I just thought it'd be something different.
Charlotte: You want to be different? Pin me up against a wall; lay one on me like you mean it.
[Charlotte gets up and walks past Grissom.]
Charlotte: You're slacking, pal.
[She sits down in front of the computer database. The computer beeps and starts running through print comparisons.]
Grissom: How long till we get a hit?
Charlotte: It could be four minutes, could be four days but you can bet your ass she'll give you something. She always does.
Grissom: "Pin you against a wall?"
[Grissom casts Charlotte a sideways glance.]

Grissom: If you try and chase two rabbits you end up losing them both.

Grissom: If you're gonna be sick, Greg, do it in the sink.
Doc Robbins: Not in the drain pan.
Greg: I don't feel sick.

Grissom: In the last 48 hours have you been anywhere else besides those two places?
Walt Braun: No. My life's pretty routine.
Grissom: It might just get a little more routine.

Grissom: It's been 24 minutes, Greg. When is this thing going to be done?
Greg: Well, with all due respect sir, it's not a baked potato. Did I ever tell you I used to live in New York?
Grissom: Is this going to be a short story or a novel?
[The mass spectrometer beeps and gives out the test results]
Greg: Excuse me. You know, heroin has a nine-minute half-life. After that, it metabolizes into morphine.
Grissom: What's the 6-MAM count?
Greg: A hundred fifty-eight nanograms per mil. Definitely not lethal. The same with your Xanax. Quarter-mil tabs, hundred micrograms per liter. Again, not lethal. There's addicts walking around Times Square with more drugs in their system.
Grissom: So Braun should still be walking around.
[Grissom turns to leave but stops]
Grissom: ...and the point of your New York story was...?
Greg: Oh, I was just going to tell you about another way to take heroin.. a suppository up the coolee. You just stand on your head, and then you let gravity...forget it!

Grissom: Jail or no jail, she won't last six months. She'll die without her son.
Sara: That would be better for both of them.

Grissom: Let go of her.
Grissom: Catherine?
Catherine: Just keep him out of here.
Grissom: [to Eddie] I don't wanna ever see you in this building again. This is our place of business, you understand?
Eddie: I always knew you two had a thing.
Grissom: Go home Eddie.
Eddie: Sure.

Grissom: Let me guess. Decomp in an enclosed space?
Sara: Yeah.
Nick: Yeah, in a zip bag.
Grissom: Lemons.

Grissom: Life's like holding a dove. You hold it too hard...
Catherine: ... you kill it.
Grissom: Hold it too soft...
Sara: ... and it'll fly away.

Grissom: Linens and towels from The Sphere on top of the washing machine, and what I believe to be sheets from the motel inside the dryer. Both positive presumptive for blood.
Nick: Think they were being smart taking the sheets, or did they just get off sleeping on 'em?
Warrick: Either way, they were sick and dangerous.
Grissom: What does that say about whoever killed them?

Grissom: Look ... could we have a truce?
Catherine: I would love to.
Grissom: Good.
Grissom: But let me do all the talking to the husband and the boyfriend.
Catherine: He had to say it.

Grissom: Look ... if this wire burned from the inside out then the fire started in the wall not on the closet floor. Discoloration throughout the conductor. It burned from the inside out. The cause of this fire was an electrical overload in the wall.
Eclie: All right, you say wall, I say floor. We differ on points of origin. The jury's only going to hear one word: Gasoline.
Grissom: Speaking of which ... where's your accelerant analysis work?
Ecklie: I personally swabbed the closet floor. Found traces of hydrocarbon chains confirming gasoline. Leave it alone, Gil. The DA agrees with me on this.
Grissom: Too many unanswered questions, Conrad. This case should not be going to trial yet.
Ecklie: No, there's only one unanswered question. Why was there accelerant in the closet? Only one person knows. And that's why he's looking at the death penalty.
