I do love a man in a bow tie.

Margaret

Bishop: Whoa. Is that you?
Ducky: Yes. Hard to believe, isn't it?
Bishop: You were hot, like really really....never mind.
Ducky: I really loved that turtleneck.

Margaret: Obstetrics? I thought you wanted to specialize in heart surgery?
Young Ducky: It's another four years of university. I've had it up to here with cadavers. To be honest, if I never see another dead body again it'll be too soon.

Young Ducky: You must be joking. Do I look like the bow-tie type to you?
Young Margaret: Well it's time to update your wardrobe. You're a medical doctor, not Doctor Who.

Ducky: What happens when frogs park illegally?
Palmer: They get towed

McGee - it's the overprotective big brother routine that's getting old.

Gibbs

Abby: So I can date him?
McGee: Absolutely not. You don't know a thing about this guy. Aside from this totally comprehensive background check.

McGee: Gibbs would never leave you out of the loop on something like this.
Tony: He didn't.
Bishop: You knew? So why bother fighting with her?
Tony: She fights back. I have a type.

You know what Tony is spelled backwards? Y not? Think about it

Tony

Tony: Am I updating the FBI?
Gibbs: No, no not yet.
Tony: Got it. And if Leia asks?
Gibbs: Geeze, DiNozzo. Make something up. She's your girlfriend.
Tony: Why - did she say something? Did she mention me by name?

Pendergast: Call me Leia
Tony: Like the Princess.
Pendergast: I hate Star Wars.
Tony: Nobody hates Star Wars.
Pendergast: You do when your name is Leia, Agent DiNozzo

Vance: So, what are you gonna tell her? (Gibbs turns to face him) Lee a hero or a villain?
Gibbs: Both.

NCIS Quotes

Bishop: Seriously? How'd you get that?
Tony: Well, it's like Gorillas in the Midst. You'll get to understand his grunts.

Torres: When I break out the glass, maybe I can rip out the bars.
Bishop: With what? Your superhuman strength?
