Warrick: I blew it.
Grissom: Yeah. But you're not the one who's paying for it.

Warrick: I just got served. Movie star's lawyer wants the shirt that I wore to the crime scene.
Grissom: So give it to him.
Warrick: I had to throw it out.
Grissom: Why?
Warrick: It was covered in the blood from the accident victim.
Grissom: Well, you have to find it; otherwise, it'll look like you've got something to hide.
Warrick: Oh, CSI's on trial now?
Grissom: CSI's always on trial, Warrick; you know this. Burden of proof is on us.

Warrick: There was this one case where a boxer put lead shot in his gloves to increase his punching power. And also ancient greek limapulists used a glove weighted with metal, called a "cestus."
Grissom: You making a classical reference?
Warrick: Yeah. I thought you'd like that.

Warrick: This guy has been in Mat's house.
Grissom: What is this?
Warrick: Mat's team won this three years ago. This trophy was given to the rec center last year. I found all this stuff in Jacobs' car. Look at this.
Grissom: If this is evidence, it needs to be tagged and cataloged.
Warrick: This is the same guy who shot Mat's daughter in the head and he's walking around laughing at us.
Grissom: Can you prove that?
Warrick: What is this? I've been putting guys away like this for years. And now that it matters it's like that you're holding me back here.
Grissom: Your job, Warrick, is to process the evidence. Objectively and without prejudice.
Warrick: I'm so tired of hearing that. I've heard it a million times. I can't be like you, I'm not a robot, ok? I, actually, care about this people.
Grissom: Y'know what? You're not working on this case anymore. I have another assignment for you tomorrow.
Warrick: Keep it.

Warrick: Two guys break and enter and get into some kind of an altercation.
Catherine: One ends up killing the other.
David: And almost Catherine. That had to be scary, huh?
Catherine: I didn't have time to be scared, David

Warrick: You ever buy a brand-new car, Griss?
Grissom: Depreciation doesn't make it a logical investment.
Warrick: It's not about logic. It's about that smell. There's nothing like the smell of a brand-new car.

Warrick: You know it's illegal in the state of Nevada to have venomous snakes?
Marty: If you handle them correctly, snakes are harmless. I know what I'm doing.
Grissom: Yeah, that's what we're afraid of.

[after Dr. Robbins has performed an autopsy on a living man, who later passes on]
Dr. Robbins: Alright David, take two.

[Looking at the meat grinder the arm is caught in]
Grissom: We're gonna have to dismantle this piece by piece.
Catherine: Yeah.
Grissom: I'll get a foreman.
Catherine: I think I can handle this.
Grissom: You know about meat grinders?
Catherine: Well, everything's pretty much plumbing. Male into female parts. Righty tighty, lefty loosey.
[Grissom just looks at her as she starts to take it apart]

[Nick and Sara sifting through rubbish they found near their victim]
Nick: Home pregnancy test, negative. Better luck next time.

[Sara gives Bobby the bullet from her friend to process]
Bobby: Hang on a second. [smiling] You get approval from Grissom, I don't want him walking in on me.
Sara: [nodding] Yeah.
Bobby: Sara Sidle.
Sara: [smiling] Yeah, I did!
Bobby: All right. Just checking!

[talking to the terminally ill suspect]
Catherine: You killed her.
Sara: I guess she killed you back.

[After Catherine was attacked at a crime scene, she fell into the victim's blood]
Catherine (to Warrick): Don't touch me, I'm evidence.

[Catherine waits outside the courtroom on the bench and Nick comes out]
Nick: Damn!
Catherine: What?
Nick: Damn, damn, damn. I forgot to put case identifiers on my dice photos.
Catherine: Date, time and file number?
Nick: Yeah. [Catherine doesn't say anything] Don't look at me that way, okay? I wrote it down on the evidence envelope. I had to move fast. The casino manager wanted us out of there.
Catherine: The dice places Tom at the murder. Victim's blood mixed with his saliva.
