Never be unreachable. (Season 3, Episode 13, Gibbs)

Rule #3

Never screw over your partner. (Season 4, Episode 14, Gibbs)

Rule #1

Mann: It's been six years. You must have something to say.
Gibbs: No, no I'm good.
Mann: Hmm.
Gibbs: If you want to talk, you should ride with DiNozzo.

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.

Tony: You just have to move on. You made a mistake.
Bishop; A big mistake.
Gibbs: Learn from it. Move on.
Bishop: I will, Gibbs. Eventually.
Gibbs: Soon, Bishop. For your own good.

Gibbs: You want to make her sick?
Comey: It's stupid, I know, but I figured if I helped her feel better again, she might appreciate me more.
Bishop: That's not stupid at all.
Comey: The thing is, I'm still working on the whole cure part. I didn't want to get her sick without that. I'm not a monster, after all.

Tony: Wow. Wowsers.
Diane: This is not what it looks like.
Fornell: Right. We were just...
Gibbs: No. I do not need the details.
Tony: I wouldn't mind a few details.

Bank manager: Would you like something to drink?
Gibbs: No. I'm good.
Diane: I'll take a water. One straw, two pieces of ice, three slices of lemon.

Bishop: I mean, I might have a better idea. Look, Eddie is coming back. If he was ditching his car, there are easier places to abandon it than at an airport. We should put it back and watch it. And when he comes to pick it up----
Gibbs: We grab him.
Bishop: Absolutely not. We follow him, see what he does, where he goes, then we grab him.
Gibbs: Works for me.

Diane: You guys are buddies now?
Gibbs: Yeah. We were thinking of starting a club.
Diane: Yeah? Well watch it, boys. I know something about each and every one of you, that you don't want anybody else to know. And I got a Twitter account.

Gibbs: You got something?
Bishop: Yeah. Uh. Maybe. You got any food around here? Anything? We'll find stuff. Come on.

Gibbs: You forgot something.
Bishop: Ahh, that's not mine.
Gibbs: It's got your name on it.
Bishop: This is my NCIS application from years ago. Before I took the job at NSA. How did you know about this?
Gibbs: Your name sounded familiar. I went back and looked it up.
Bishop: That's why you took me along today. You play chess too.
Gibbs: I wanted to see if you're still up for a challenge.
Bishop: Why?
Gibbs: I'd like to keep you around. Joint duty assignment.

NCIS Quotes

McGee: All right. Well you should probably know that Abby and I used to date?
Bishop: Ew. Like, each other?
McGee: Yeah.
Bishop: Wait - isn't that a violation of rule 12, never date a....
McGee: It was a long time ago. After we'd broken up, one night I went to her lab. Found a scribbled piece paper; a list. Potential boyfriends had to fulfill certain conditions by a pre-arranged date or else, goodbye.
Bishop: Such as.
McGee: Things started off relatively normal: opening the door for her, flowers, putting the seat down. Then around number 8, it gets uh...
Bishop: What?
McGee: Does she know you have these?
Bishop: Does she know you have these?
McGee: Yeah she wasn't happy when she found out.
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.

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.
