Grissom: I guess clothes do make "The Man."
Catherine: In this case, "The Man" makes the clothes... and produces the music... and represents the athletes... when he's not involved in street shootings, of course.
Grissom: And when you asked him what he was wearing the night of the murder, he couldn't remember?
Catherine: As far as he's concerned murder is just another way to separate himself from the Calvins and Ralphs of the world.
Grissom: Calvin and Ralph?
Catherine: Klein and Lauren. Fashion.
Grissom: Oh. Well, for most CSIs, fashion is irrelevant.
Catherine: Speak for yourself. The only thing between me and a wardrobe like this is a few extra zeros on my paycheck.

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: May we come in?
Lady Heather: Say the magic word...
Brass: Warrant.

Grissom: Okay, Doc, tell me something I don't know.
Dr. Robbins: Okay. In fourth grade, I dropped out of karate class because a kid half my size made me cry.
Grissom: About the body.

Grissom: So, let's see. You surf, you scuba dive. You're into latex, you like fashion models and Marilyn Manson. And you also have a coin collection?
Greg: Weird, ha?
Grissom: Well, I race cockroaches.

Grissom: There's a theory in art that the Mona Lisa was really a feminized version of Leonardo Da Vinci himself.
Sara: Concept suggests ... Deep down we're all narcissists?
Grissom: Yeah. What attracts us the most is ourselves.

Grissom: Tom Haviland's attorneys are not waiving time.
Nick: Are you serious?
Sara: They're actually exercising their right to a speedy trial?
Gil: No requests for continuances, no stall tactics. They're pushing for their day in court.
Warrick: Good defense attorney always does the last thing you expect.
Catherine: Yeah. What typically drags on for months has now been put on the fast track and the prelim is less than 72 hours.
Greg: I'm only done processing half the evidence.
Catherine: You're going to have to call in help, because if the judge thinks that our evidence isn't strong enough to go to trial, he's going to dismiss the charges on Tom.
Sara: Can't the D.A. drop the charges and we'll refile when we get our evidence together?
Catherine: Sure, but the odds are that Tom will relocate to Europe and pull a Polanski.
Greg: And what's a Polanski?
Grissom: Get-out-of-jail-free card. One more thing: Westcott just added a forensic scientist to their roster. She wants him to examine every piece of evidence we have against Haviland.
Nick: As soon as it's processed they'll get a copy of our report.
Gil: They're entitled to see it as it's processed.
Nick: I've never done a case where the defendant took advantage of that rule of discovery.
Gil: Well, when you can't attack the evidence itself, you attack the method of gathering the evidence.
Sara: So who's their guy?
Grissom: Dr. Phillip Gerard.
Sara: Phillip Gerard? Your mentor is their forensic scientist?
Grissom: Yeah. Marjorie Westcott's a smart lawyer.

Grissom: What happened to your enthuasism, Greg?
Greg: Well, everytime I make a DNA match in here my world gets a little smaller. Out there I felt large.
Grissom: Out there... means a pay cut.
Greg: It's not about the money.
Grissom: That's good to know.

Grissom: You know what's really sad? This wasn't just a murder. It was a hate crime. Kevin Marcus hated himself.

Grissom: Your guys didn't get any extended body photos?
Brass: Chest, hands, arms right there.
Grissom: I need lower extremities for comparison.
Brass: Hey, Marjorie Westcott blew in here and shut us down. She said if we wanted full body shots we were going to have to get a court order. So the D.A.'s working on it.
Grissom: When, between testimony?
Brass: No kidding. Meanwhile, we're presenting half a case to a judge.

Grissom: [to Dr. Gerard] What happened to you? You were a pioneer in forensic science. How many bad guys did you put away in Hennepin County?
Dr. Phillip Gerard: My share. How many innocent men have been locked away since then because of sloppy investigating shortcut forensics?
Grissom: You look for mistakes in any lab, you'll find them.
Dr. Phillip Gerard: I shouldn't be able to, Gil.
Grissom: Humans are fallible.
Dr. Phillip Gerard: Not this fallible: compromised blood, sweetheart deals...
Grissom: No, no, no, no. You're subverting good evidence. These are good people.
Dr. Phillip Gerard: The accused is entitled to the best defense possible.
Grissom: The accused is entitled, yeah. He's a movie star, that's why he's entitled. He's killed two women. You know it. But you're willing to decimate these CSIs so that you can spoon-feed a jury into letting him walk.
Dr. Phillip Gerard: A jury believes me because of my reputation just like they do you.
Grissom: The difference is, Philip, I get the same paycheck regardless of what I testify to.
Dr. Phillip Gerard: I'm saying this as a friend. For the reputation of CSI, tell the D.A. to drop this, re-file down the road.
Grissom: What about the victims' families? Who's their friend? [Dr. Gerard doesn't answer] My guys will see you in court.

Lady Heather: Unfortunately the language we speak in here doesn't necessarily translate to the world out there.
Grissom: No, in here, the submissive has the power... all he has to do is say the safety word and everything stops.
Lady Heather: Very good, Mr. Grissom.
Grissom: I'm just repeating what I've heard.
Lady Heather: You're a good listener.
Grissom: Part of the job.
Lady Heather: So, this is work?
Grissom: Yes, but I value your insight.
Lady Heather: I'm flattered...but you already seem to know the answers to your questions. You keep me in proximity when I walk away [She moves closer to him] and when I'm close you watch my lips. Are you losing your hearing?
Grissom: I'm losing my balance.
Lady Heather: Your sense of self?
Grissom: No, I know who I am.
Lady Heather: Do you?
Grissom: Yes... I do. [He touches one side of her cheek with one hand then the other with his other hand] You can always say "stop".
Lady Heather: So can you.

Marjorie Westcott [to Catherine]: You took your clothes off for a living.
Catherine: For a very good living.

Marjorie Westcott: [on television] Aside from the fact that the other woman in this case also known as Tonya is still at large and is still a likely suspect in this murder the evidence Las Vegas CSI did collect the evidence they're using to railroad my client, Tom Haviland, has been completely and irretrievably compromised. I'm holding in my hand compromised, contaminated evidence, ladies and gentlemen. CSI should be ashamed; and you, as citizens, should be outraged. This is not how we do things in America.

Marjorie Westcott: [to Sara] You date... you and Hank. You share a subtle communication. Did he move the bra to where you might have wanted it?
Sara: I didn't want it anywhere. I collect evidence without emotion.
Marjorie Westcott: You do get emotionally involved, though with the men on your cases. Hank Peddigrew isn't the first time.
Sara: Excuse me?
Marjorie Westcott: A murder investigation at the residence of one Charles Renteria. Eyewitness stated he saw you and your supervisor Gil Grissom standing alone outside and you were touching him in a romantic gesture.
Sara: I brushed chalk from his face.
Marjorie Westcott: Is that what they're calling it now?
Prosecutor for CSI: Objection, your honor.
Sara: Drywall dust. We were looking for a body.
Marjorie Westcott: It's a fair question, your honor. Just how far will Ms. Sidle go on the evidence to please her boss, Gil Grissom, whether he returns her attentions or not?
