CSI: Crime Scene Investigation Season 4 Episode 20

Warrick: Break the bad news to the wife?
Sara: Oh, I didn't have to.
Warrick: Women always know, huh?
Sara: Not always.
Warrick: I think so. Women always know when the man is straying.
Sara: What are you, the voice of experience?
Warrick (laughs): No. I'm a really nice guy.
Sara: Oh, I believe you.

Mrs. Senteno: I married a cop. With that comes alcohol and women to take the edge off. First time ... he said it meant nothing. He promised never to do it again. By the third time ... I told him to stop confessing. I wasn't going anywhere.
Sara: Don't ask, don't tell.
Mrs. Senteno: I wasn't willing to trade my family for the flavor of the month. That doesn't make me pathetic.

Will Warshall: If I'm going to kill a guy, I'm not going to do it with twenty thousand cops around.
Catherine: Well ... sounds like you've been giving it some serious thought.
Will Warshall: Well, every cop does. My way? A sniper shot ... two hundred meters out. Coleman'd never even hear the "am" in "blam."

Doc Robbins: Well, the race isn't the only reason these guys come to town. It's a good party.
Grissom: Too much running, too much partying?
Doc Robbins: L.A. S-E-S. They go all out.
Grissom: Work hard, play hard, die young, leave a good-looking corpse.

David: So, how was your run?
Greg: I'm still alive.

Catherine: How many cops are in town this weekend?
Grissom: Twenty thousand. And the road is closed to civilians.
Catherine: Spring break with a badge. Well, this ought to be fun. Every suspect's in law enforcement.

(About trace evidence)
Sara: Are you saying that the gun was wiped down and the prints were planted?
Hodges: No, you're saying that. I don't get to say that.

(Catherine is running and Grissom is in a SUV driving beside her and he's playing the theme to "Chariots of Fire")
Catherine: What the hell kinda music is that?
Grissom: Inspiration.
Catherine: Sedative.
Grissom: Okay. (he changes the radio so it plays country music) How's this?
Catherine: How 'bout something that doesn't twang? (he changes it to "Are You Gonna Be My Girl" by Jet) Better.

Grissom: Sooner or later, everybody gets replaced.
Mendez: Talk to me when it happens to you.

Lt Mendez: I am not going to miss this.
Catherine: You're not going to miss the competition?
Lt Mendez: I just made Lieutenant. I've got nothing to prove.
Catherine: A man with nothing to prove. Now that would be a first.

(after Grissom pulls the SUV off of the road during her run)
Catherine: What are you taking a leak? The follow car is supposed to stay with the runner! We've been training for months, man. 20 C.S.I.s, 120 miles.
Grissom: Don't blame me. Blame him. (shines his flashlight on a corpse)

(a corpse found on the roadside turns out to be a LAPD SES officer)
Catherine: So much for the race.
Grissom: At least we didn't come last.

Lt. Mendez: Those the best you got? (point over to Grissom and Catherine)
Brass: Yeah, yeah, you got lucky.
Lt. Mendez: Well, if they're not I'll fly mine in.
Brass: Let me put it to you this way - I'd want them investigating my murder.
