Cabot: As you know, the Navy is trying harder than ever to eradicate sexual assault in their ranks.
Gibbs: Was Ensign Tate a rape suspect?
Cabot: Right to the point, as always. No Gibbs, Tate was a second-party complainant. He reported an assault on behalf of a friend.

[after killing Salim] Let's go home.

The best way to keep a secret? Keep it to yourself. Second best? Tell one other person, if you must. There is no third best. (Season 4, Episode 11)

Rule #4

Hegarty: Disaffected young western males, here and in Europe are targeted by terrorist recruiters. Most are troubled kids, seeking redemption and violent action.
Vance: And they buy into jihad?
Hegarty: Media-savvy militants in Iraq and Syria post graphic photos and slip recruitment videos on Facebook and Twitter. Reach right into a kid's bedroom. Parents have no idea what's going on. This is Cleavon Smith, a former Detroit gang member, born again Muslim, who was known as Abu Hussein when he died last week on the killing fields of Syria's civil war.
Gibbs: Do we know how many Americans are fighting in Syria?
Hegarty: About a dozen. We can stop them from returning. It's the ones we don't know about that are the concern, like this Nasry you've uncovered.

Sometimes you're wrong. (Season 7, Episode 24, titled "Rule Fifty-One")

Rule #3

Gibbs: Anything I can do?
Bishop: Uh, it's pretty self-explanatory, really.
Gibbs: Did you check to see if that little gizmo there is attached to that other giddy-bop?
Bishop: Mmm. Not yet. You think that'll do it?
Gibbs: If you spit on it. Sometimes that works.
Bishop: All right.
Tony: Oh, come on!

Tony: Don't believe the word he says. We've got motive, we've got opportunity.
Gibbs: Ahah.
Tony: I know. Why'd he come back?
Gibbs: It's a good question... Boss.
Tony: Boss?!
Gibbs: Was your case, wasn't it?
Tony: Yeah. You're not going back to Mexico, are you?
Gibbs: Your case, your lead.
Tony:(smiles) Really?
Gibbs: Yeah. I think it's even a rule.

Ziva: I'm sorry Tony. I know you wanted the car but I just didn't think it was a good idea to sell it to you.
Tony: Why not?
Ziva: Because I really liked my Mini.
Tony: Me too!
Ziva: And I didn't want anything to happen to it.
Tony: What are you saying?
McGee: She's saying you're a car killer.
Tony: What?
Ziva: A car killer.
Gibbs: Everybody needs a hobby.

Leroy Gibbs: Leon?
Leon Vance: She's dead. My wife is dead, Gibbs.

Bishop: Should we go to the hospital?
Gibbs: No. No, we should find Parsa.
Bishop: How?
Gibbs: You start at the beginning, Bishop. Come on. This is what you do. Come on, come on, come on. Bishop. Come on! Get to work.
Bishop: Okay.
Gibbs: You find him. Get this son of a bitch.

Always be specific when you lie. (Season 1, Episode 23)

Rule #7

NCIS Quotes

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.

[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.
