(Gibbs walks into the squad room)
Gibbs: Come on, grab your gear. Don't wanna miss the school bus.
Tony: Class trip, boss?
Gibbs: Got a dead petty officer in a high school stairwell. Janitor found him this morning.
Tony: Hmm. (Starts singing) Wheels on the bus go...
Gibbs: (Gibbs joins in) ...round and round, round and round, round and round...

Admiral Chase: Does Agent David carry a weapon?
Gibbs: She is a weapon.

(Gibbs walks in on Tony and McGee with the blow-up doll)
Tony: Morning, Boss!
McGee: This isn't what it looks like, Boss.
Gibbs: Well, what is it, Tim?
McGee: Erm...a joke...I think. A really bad, practical joke.
Gibbs: I'm not laughing. (Gibbs turns and heads for his desk) Lose your gal-pal. (To everyone) Grab your gear. Got a dead Marine in Springfield.
(McGee tries effortlessly to hide the blow-up doll as the rest of the team head for the elevator)

Abby: Gibbs! Trying to give me heart palpitations?
Gibbs: No. What've you got, Abbs?
Abby: Heart palpitations.

Gibbs: Facebook. That's that thing that some people... do stuff with?
Ducky: The term is social networking.

Gibbs: The plane's missing.
Tony: It's been Kai-jacked!
Ziva: Did you really just say that?
Tony: I regret it already.

Admiral McGee: My relationship with my son is none of your damned business.
Gibbs: You make him think he's nothing. You're the one with nothing.

Tony: I have to break one of your rules, boss. Number six: never say you're sorry. I let things get out of control in the hotel room.
Gibbs: Ah, it's covered. Rule eighteen.
Tony: Oh, yeah. It's better to seek forgiveness than ask permission. Am I forgiven?
Gibbs: No.

Gibbs: What's that?
Ducky: His liver, riddled with inoperable tumors. It doesn't appear to have been under treatment. I'd have given him six months.
Gibbs: Made killing himself easier.
Ducky: Pity does not validate cowardice.

Palmer: I take it you heard?
Gibbs: Mmm hmm.
Palmer: Yeah, she saw the baby and just....I guess she felt the same way we felt when we first saw him. Can't fault her for that, right?
Gibbs: You should go home.
Palmer: I will. Yeah Breena and I, we just wanted to get all this stuff out of the house. You know, we wanted to give it back as soon as possible.
Gibbs: We.
Palmer: Me. She's hurting too, but she is so much stronger. She's ready to try again. And me - I feel like I can't breathe. I never felt this bad in my life, Gibbs.
Gibbs: Well, just wait until it's 3:00 in the morning, and your kid's running 104. You're just getting started.
Palmer: That's the point. I'm not starting, you know? Maybe I never will.
Gibbs: Well then fight for it, Palmer! That's what you do. You fight for your family. And sometimes, you fight like hell just to have one.
Palmer: You want me to fight, I feel like I just went ten rounds with Joe Louis.
Gibbs: Do you want to be a dad, Palmer? Because right now, this is being a dad.
Palmer: Maybe I'm not ready.
Gibbs: You wouldn't feel the way you feel, right now, if you weren't ready.

Tobias: This is a big deal, you letting me drive your car.
Gibbs: Whatever, you already slept with my wife.

Fred: Uh, Special Agent Gibbs?
Gibbs: What, Fred?
Fred: I have a problem. Uh, Anthony DiNozzo, Sr. is not only staying in a $1,500-a-night suite, he's also running up a huge tab. Spa treatment, manicure, room service, French champagne, and I just got a call, he's ordered a limousine for tonight.
Gibbs: Guess you haven't got the bill for the flowers yet?

NCIS Quotes

[voiceover] Anyone can achieve their fullest potential, who we are might be predetermined, but the path we follow is always of our own choosing. We should never allow our fears or the expectations of others to set the frontiers of our destiny. Your destiny can't be changed but, it can be challenged. Every man is born as many men and dies as a single one.
