Greg:(Looking at Nick's sperm) Nick's little soldiers.

Grissom': Hey, stop! Evidence! (Det. O'Riley stops and changes his course, staying off of the main floor and on the sides of the room)
Det. O'Riley: We got to hug the wall? This is the only room with no blood in it. There's nothing to disturb.
Grissom': You guys will never get it, will you?
(Seeing a couple officer's throwing up)

Grissom': What's wrong with your two guys?
Det. O'Reilly: They've been inside.
(Grissom looks at the house and sighs)

Grissom: (angry) Are you looking for work?
Nick: I just...
Grissom: The sign says, "Do Not Enter," Nick. You can't read anymore? You're blind? What?
Nick: Grissom, this is important.
Grissom: (furious) This is important. Sometimes in interrogations, Nick, you get one chance, one answer. And while I'm out here screwing around with you he's in there thinking up an answer that he didn't have before you walked in.
Nick: We matched the DNA taken from Lacey Duvall to a cold case in Texas ten years ago.
Grissom: And?
Nick: The suspect's name was Chad Matthews.
Grissom: C.M. The cuff link. Okay, I'm starting to forgive you.
Nick: Sara ran Patrick Haynes' social. The real Haynes is deceased. So Patrick Haynes is Chad Matthews and Chad Matthews is on the run.
Grissom: And he just ran into us.

Grissom: (finding a tooth in the fireplace)I think the tooth fairy might have just left us a piece of Portia Richmond.

Grissom: (looking at the victim) The Van Gogh effect... in stereo. Both ears gone.
Catherine': A perfectly symmetrical amputation. Means he was looking directly at the bomb when it went off.
Grissom: So either it drew his attention or it was contained in something that seemed benign.

Grissom: [Laughing] Jacks or better. You're under arrest.
Suspect: Oh, yeah? What for?
Grissom: First-degree murder.
Suspect: Oh. On what grounds?
Grissom: [Looking at suspect's boots] Roof dust.

Grissom: [Looking at beetle found at crime scene.] Can I keep him?

Grissom: [Looking at detached head] It means 6 - 8 hours ago someone lost their head and then... someone lost their head.

Grissom: [reading] I've killed 5 women...catch me if you can.

Grissom: [swipes a yellow substance that has dropped on the leg of a shopping cart and licks it]
Brass: Oh, that's sanitary.
Grissom: Mustard. [Glances behind, noticing a bunch of jars of mustard on the shelf] Did you have any clean-ups in this aisle today?
Store manager: Yeah, as a matter of fact, we did.
Grissom: Life holds no surprises. [Takes a jar of mustard from the shelf, checks the price and hands two dollars to the store manager] $1.98 for the mustard, plus my two cents. [Takes the jar and drops it at Brass' feet. The jar shatters, splattering mustard on Brass' shoes and pants]
Brass: What are you doing?!
Grissom: Now, where do you go?

Grissom: [to Catherine after finding a severed leg] Well Watson, the game's afoot.

Grissom: [yelling at Warrick] We solve these cases regardless of race, color, creed, or bubblegum flavor!

Grissom: Based on the auricular surface I'd say she died when she was about twenty.
Nick: She?
Grissom: It's in the hips. Pelvic bone is definitely female. You know, for a ladies' man you don't know much about bone structure.

Grissom: Catherine. (Catherine looks at Grissom and doesn't say anything. He notices that she walked out of his office) What are you doing?
Catherine: The carnival case. I'm taking it.
Grissom: The carnival case?
Catherine: A six-year-old girl died on a ride at the carnival over on Washington. The paperwork's on your desk.
Grissom:(nods and glances at his office behind her) Did you straighten up my office while you were in there?
Catherine: You think I overstepped? ... These people come to town, they commit crimes and they leave. I just want to get there before the carnival moves on.
Grissom: Okay. Take Sara with you.
Catherine: She's meeting me there.
