That is why it is called a batnap.

Ziva

Butt out McGee. Butt off my desk, Borin.

Gibbs

We've gone from Socrates to Snooki.

Ducky

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

McGee: The last time you did my expense report for me, you reclassified my meals as 'livestock feed'!
Tony: Well, that was childish.
McGee: I was audited!
Tony: Well, that makes us even.

Tony: Maybe instead of having a midlife crisis, I'm having a midlife crazy.
Ziva: Look, you are not crazy. You are just... growing up. And some lessons are more painful as we grow older, because the stakes are higher. You need to find balance! Yes, yes, yes, you need to treat people more respectfully, especially when it comes to matters... of the heart. But you need to be who you are.
Tony: And who am I?
Ziva: You are Tony DiNozzo. The class clown. And that is why we love you.

Tony: Agent McGee, probationary agent to be good morning.
Ziva: Looks like Tony.
McGee: Doesn't sound like him.

Abby: I've had problems with visitors, so he [McGee] was just being overprotective.
Neisler: Protective of what, your butt? He couldn't stop checking it out when your back was turned.
Abby: Really?
Neisler: But I can see why you'd want to keep things casual.
Abby: Why is that?
Neisler: What if he's 'the one'? You're obviously married to your work, it's too soon to meet 'the one'.
Abby: We're done. (To Gibbs) Gibbs, can you make him go away, please?

McGee: Hey, where is Boss, anyway?
Malachi: He's in Interrogation.
Liat: With Director David.
Tony: Oh! This is like Clash of the Titans. We should be there.
Ziva: It's a closed show.

Agent Sharp: It's like herding cats, huh, Agent McGee?
McGee: I don't like it at all, Agent Sharp. I've got a dozen other retired agents. I have Branch, I've got Morrow, I've got Nedrow. I have more directors than the front row of the Oscars.

Ziva: We cannot really be sure that, because this girl crossed paths with him here yesterday, we will cross paths with him today.
Tony: Also can't be sure that Gibbs will be swilling coffee when we get back to the office, or you'll fumble a simple American expression, or that McGee will sleep alone tonight - but, people do tend to follow patterns.

Gibbs: Officer Hadar. You almost made me spill my coffee.
Hadar: Americans... You can never just say hello.
Gibbs: How about shalom? Hello and good-bye.
Hadar: And peace, Agent Gibbs.
Gibbs: Not a lot of that when you're around.
