Give Victor a break for being him, not for being someone else.

I've seen bad turn to good many times. You can't lose faith.

Gibbs: I'm on the other side now. I tried to catch Wescott, he wouldn't let me.
Ducky: No, you can't Gibbs, but you can call him.

(Gibbs and Ducky are in Autopsy, looking over Sgt Wooten's body.)
Ducky: These bruises and lascerations could be consistent with somebody hitting a target repeatedly.
Gibbs: The target was the wife, Duck. I wouldn't blame her if she did this.
Ducky: Nobody would. But that doesn't make it any less of a crime.

(Gibbs walks in on Tony and McGee with the blow-up doll)
Tony: Morning, Boss!
McGee: This isn't what it looks like, Boss.
Gibbs: Well, what is it, Tim?
McGee: Erm...a joke...I think. A really bad, practical joke.
Gibbs: I'm not laughing. (Gibbs turns and heads for his desk) Lose your gal-pal. (To everyone) Grab your gear. Got a dead Marine in Springfield.
(McGee tries effortlessly to hide the blow-up doll as the rest of the team head for the elevator)

Ducky: Tony! Meet former medical examiner, and my esteemed predecessor, Dr Walter Magnus. Magnus is my guest.
Gibbs: Bringing guests to crime scenes now, are you, Duck?
Ducky: Yes, well, only ones that used to be me!

(Gibbs walks into the squad room)
Gibbs: Come on, grab your gear. Don't wanna miss the school bus.
Tony: Class trip, boss?
Gibbs: Got a dead petty officer in a high school stairwell. Janitor found him this morning.
Tony: Hmm. (Starts singing) Wheels on the bus go...
Gibbs: (Gibbs joins in) ...round and round, round and round, round and round...

Butt out McGee. Butt off my desk, Borin.

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

(McCallister unscrews the top of his cane)
McCallister: Damnit! I brought the wrong cane. Other cane's got the flask.
Gibbs: Hey, Riley. Where'd they dig you up? (gestures to the coffee) Keep you sharper.
McCallister: (scoffs) Please. The coffee here is weaker than a Frenchman's handshake.

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.

Ziva: We killed you first, Tony.
Tony: Oh, I've seen it a million times. The pretty popular girl gets jealous when the hot new transfer comes in and steals all the spotlight. Well, it's pretty much a staple of every high school movie from the seventies and eighties : Heathers, Fast Times ...
Gibbs: Who got jealous in Fast Times? God, I like Phoebe Cates.
