High-tech case - low-tech ass-kickin'!

Abby: I don't understand! I mean why does autopsy get back up power and I don't? MTAC I get that, but what does Ducky have that I don't?7
Gibbs: Corpses.
Abby: I'll get some corpses!

Gibbs: Book 'em, Dan-ozzo.

You, Gibbs, are an enabler!

Tony: It's been Kai-jacked!

[voiceover] Anyone can achieve their fullest potential, who we are might be predetermined, but the path we follow is always of our own choosing. We should never allow our fears or the expectations of others to set the frontiers of our destiny. Your destiny can't be changed but, it can be challenged. Every man is born as many men and dies as a single one.

Tony: Who says we want you?

Ziva: And what do you know about the American Dream?
Tony: I'm a white male between the ages of 18 and 49 with a gun. I AM the American Dream.

Bishop: What?
McGee: Does she know you have these?
Bishop: Does she know you have these?

Bishop: These are all very specific.
McGee: Yeah.
Bishop: These ideas apply to you?
McGee: No those rules weren't in place when we were together. At least I don't think so.
Bishop: What's with the two month cutoff? Abby's sabotaging herself. I've seen stuff like this before. We have to talk to her.

McGee: You know something I don't? Working tonight and tomorrow night?
Tony: No, Tim. It's just that Zoe's parents are in town and they want to have dinner. I'm not ready for that.
Abby: So you deceived her.
Tony: I was put on the spot. I was not prepared.
McGee: Whoa. Hey. What are you afraid of?
Tony: I don't know.
Abby: They're probably really nice.
Tony: I'm sure they are. I've just never had dinner with the parents of a woman I'm seriously involved with.
McGee: That's not true. What about Jon Benois?
Tony: No, technically that wasn't me because I was undercover as Tony DiNardo, professor of film studies. I wasn't myself back then. Meeting the parents for dinner could trigger a whole chain of events.
Abby: It's just dinner, Tony.
Tony: You have dinner yet with Ranger Burt's parents? I didn't think so. Then put down the gavel, take off the robe and stop judging, both of you.
Abby: Okay.
