Ziva: You cannot even work your email properly! You always reply to all. It drives me absolutely nuts! You know, when it comes to computers, you are almost as incompetent as Gib - [looks around]
Tony: You thought Gibbs was behind you. You know why? Because sneaky people expect sneakiness. It's a vicious circle.

You cannot trust a man whose loyalty has a price.

Ziva

Ziva: Being stuck at that desk has given me a lot of time to think. Being a visitor here is wrong.
Gibbs: What does that mean, Ziva?
Ziva: I need your signature on this. I want to be an NCIS agent.
Gibbs: I don't even know if that's possible. You would have to resign from Mossad.
Ziva: Already have. Sent my father an email.
Gibbs: Hmm. Now what's he think about that?
Ziva: It does not matter.

Abby: I only take orders from one person: Special Agent Leroy Jethro Gibbs. Unless he asks me to do it, it doesn't get done!

Ziva: That is total salami!
Tony: Bologna.

Tony: You failed your polygraph! That's not good.
McGee: No, I didn't fail it. They said I have to take it again.
Tony: Why would you have to take it again? Don't ask, don't tell. You didn't make the mistake of coming out, did you?
McGee: I don't have anything to come out about.
Tony: Stick to that story, McQueen.

Tony: I thought you weren't sure what to say?
Ziva: I guess I had a long time to think about things.
Tony: I'm sorry, Ziva.
Ziva: No. It is I who am sorry.

Tony: Taking the tour?
Ziva: I have my first psych evaluation.
Tony: Oh, yeah. I always loved those.
Ziva: I'm sure. You get to talk about yourself the entire time.

McGee: Thanks for volunteering me.
Tony: C'mon. You said you always wanted to travel.
McGee: On my own time.
Tony: On your own dime? Are you crazy, you could never afford this!

Tony: Come on, computers are your thing! If I had a thing I'd want to show it off.
Gibbs: There are rules against that, DiNozzo.

Abby: You would make a great Santa.
McGee: I guess you just gotta believe.
Abby: I do believe.

I think we've found the entire cast of Hee Haw.

NCIS Season 7 Quotes

Salim: So what are you doing here?
Tony: There's only one force on Earth that can short circuit a man's better instincts, put fire in his veins and make him dive head-long into danger without regard for his well being. Vengeance. I'm here to kill you.

Salim: DiNozzo. It's an Italian name.
Tony: An educated man.
Salim: I got my B.S. from Yale University.
Tony: [scoffs] I got my B.S. in the streets ... You guys got a lousy football team.
