(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)

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

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

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.

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

I'm not alone.

Gibbs: You're superstitious?
Vance: I'm a little stitious.

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.

Tony: Maybe I was wrong about a lot of people.
Gibbs: Are we still talking about the case?
Tony: It's so interesting. No one will say her name. Have you noticed? It's like she's dead. Every time I look at her desk, every time I close my eyes....I just feel like I made a mistake. Like I made the wrong decision. Only it wasn't me who decided. So yeah - I'm probably wrong to think Anton's innocent in all this.
Gibbs: I'll trust you any time.

Ziva: Why do I have to study all this and you don't?!
Gibbs: I was born here.
