Neeley: You have reason to believe they're on board?
Ziva: Stationary target. Closed quarters.
Neeley: A modern day Orient Express.
Ziva: The killer would just need an inconspicuous weapon.
Neeley: Like what? Listen, I've been doing this for a long while and I doubt that there's anything -
Ziva: Headphone cables make for a perfect garrote, and plastic silverware is not as safe as you might think. I once killed a man using a credit card.

Ziva: A team of Homeland Security officers will be waiting for us when we land. Outside the terminal an NCIS detail will take over.
Marshall Neeley: Not taking any chances in case your new hitman tries something on the ground, huh?
Ziva: Which is why we must consider the possibility they may try something on the plane, where Nora is more vulnerable.

Tony: All right, Annie Leibowitz, what's wrong with my pictures?
Nora: Well, they're sort of soulless. Analytical. They look like postcards or -
Ziva: Crime scene photos.

Tony: I just sort of feel like you can use negative space to push the image, you know? It's sort of like a geometrical thing with the light coming across. I was trying to use these geometric lines and spacing. Sometimes I think maybe I should have done something more creative with my life.
Nora Williams: No, I think you're in the right profession.

There's something on the wing. Classic Shatner on The Twilight Zone.

Tony

Gibbs: You've been distracted by your father.
Tony: It's that obvious?

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.

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

Ziva: Okay, so how many amendments to the Constitution?
Gibbs: The Bill of Rights is the first 10, prohibition is 18. I'm guessing 23.
Ziva: Twenty-seven!
Gibbs: Nobody likes a smart ass, David.

Tony Sr.: You forget, we took some great vacations together.
Tony: Like the trip to Maui where you left me in a hotel room for two days and I was 12 years old?!

I get it. It must have been tough. Your wife dies and you're left with an eight year old kid, but your solution, Dad, was to warehouse me in boarding schools and summer camps, and half the time I never knew where you were or what you were doing. I needed a closer relationship.

Tony

Abby: Maybe Tony didn't have a mother. Maybe he was cloned!
Ducky: There certainly is a strong familial resemblance.

NCIS Quotes

Tony: One other question, I know you're an expert in English history. And I was just wondering, have you ever heard of Archibald Drummond, the 17th Earl of Trent?
Ducky: The Earl of Trent. No, I can't say I have. Why?
Tony: I was just wondering. Thanks.

McGee: Rule number 70 - keep digging till you hit bottom.
Abby: McGee! There is no rule 70.
McGee: Well, I--
Abby: You just made up a rule. This McGibbs thing has really gone to your head. I don't even recognize you right now.
