Dinozzo Sr.: Is that Ziva?
Tony: [frustrated] Yeah.
Dinozzo Sr.: Junior, get my bag. Oh wow, Ziva, look at you! What do you say, sweetheart?
Ziva: Hi!
Tony: Watch the hands!
Dinozzo Sr.: I'm so happy to see you!
Tony: Let's go!

DiNozzo, Sr.: What's on your mind?
Gibbs: Your son.
DiNozzo, Sr.: What's junior done now?
Gibbs: Tony likes to hide behind the face of a clown, but he's the best young agent I've ever worked with.
DiNozzo, Sr.: Well, I'm glad to hear that.
Gibbs: When was the last time you talked to him? I mean really talked to him.
DiNozzo, Sr.: We keep in touch.
Gibbs: Four years ago your son came very close to dying from pneumonic plague. I expected to see you. You didn't show then. Why are you here now?
DiNozzo, Sr.: He never told me he was sick.
Gibbs: Oh, so you don't keep in touch.
DiNozzo, Sr.: What's your point?
Gibbs: Tony inherited his personality from you, but I get the feeling there's a lot about your life you don't share.

Director Vance: State Department has appointed Ms.Hart to be Alejandro's legal counsel for the task force.
Gibbs: Of course they did.
Alejandro Rivera: I met Allison in Mexico City. We work well together.
Allison Hart: Alejandro was very helpful in my securing Colonel Bell's release from prison.
Gibbs: Maybe we shouldn't be cooperating, Leon.

Dr. Cranston: It's all about responses, Gibbs. You, Vance, ...your agents. We keep things piling up inside... even the harshest response seems appropriate.

Dr. Cranston: It's clear to me we all react to life's challenges in different ways - your people are no exception. Some fight death and some embrace its solace. Some recognize their fate and others do whatever is necessary to alter it. Sometimes we defy other's expectations and, occasionally, we rise to meet them. But the constant is being true to ourselves. We do what we have to when we have to. We react - for better or worse.

Dr. Cranston: Man walks into a bar. Asks the bartender for a glass of water, bartender pulls out a shotgun, fires a blast just missing the man, man says "thank you" puts a tip on the bar and exits. Why the '"thank you"? Why the tip?

Dr. Cranston: The thing that puzzles me, with all this change, allegiance to country, of the type of men you're drawn to, what is it that you are looking for? What is it that you want?
Ziva: I want something permanent; something that can't be taken away. Is that too much to ask?

Dr. Cranston: What do you see when you look at him, Agent DiNozzo?
Tony: A man works his whole life, dedicates himself to his job, and then has nothing to show for it.
Dr. Cranston: How does that make you feel?
Tony: Afraid. I'm a good agent, Dr. Cranston. A really good one.
Dr. Cranston: I know. So do a lot of other people. Maybe Agent Todd was hard on you because she knew what you were really capable of. Too bad she never got a chance to tell you.
Tony: I think I just realized who you are, Rachel.

Ducky: (to Ari Haswari) I look forward to weighing your liver.

Ducky: (to Palmer) My father used to say "You must live for today; because yesterday is gone, and tomorrow may never come."

Ducky: (to Tony) You sound like Gibbs.

Ducky: [about the morgue] This is the place, where death rejoices in teaching the living!

Ducky: [Describing a carpet] Looks like sisal. It's a naturally stiff fiber woven from the leaf of the cactus plant. It doesn't matt, trap dust, build static, makes it ideal for carpeting. Personally, I prefer a good shag. [stares from everyone, while Palmer grins widely] From a purely forensic standpoint, I mean.

Ducky: Cellular communication, text messaging, squeaking...
Palmer: Tweeting, Doctor. Like the little yellow canary and the puddy cat. I used to love that cartoon...

Ducky: Do you suspect foul play?
Gibbs: Well, you know me, Ducky. I suspect everything.
Ducky: Yes, that's an admirable trait for an investigator. And also, I suspect, the reason your three marriages ended in divorce.
Gibbs: Really? And all this time, I thought it was because I'm a bastard.
