Tony: Who would even want to steal Arnett's body.
Abby: Thank God Burns isn't around to put it in his blog.
Tony: Someone else will fill the void.

Ducky: If the cases are connected, does that infer that Arnett was also murdered?
Gibbs: And we've got our hands full.

Gibbs: Bottom line?
Ducky: Lt. Arnett's death was accidental.

Fraternization in the workplace. Never a good idea.

Tony

[to Ben Franklin] A penny saved is a penny earned.

Tony

There were three men at a fake bachelor party. What were they doing there? No one knows.

Tony

Ziva: Hello, Abby.
Abby: WHAT THE HELL IS WRONG WITH YOU? How could you have doubted Tony, after everything you've been through together? You really think Tony killed Rivkin because he was jealous?! You weren't thinking. That's right, you weren't thinking. Although I supposed I can understand your initial reaction. You were at an emotional time for you, when people act rashly. But to tell Gibbs that you didn't trust Tony?! Which again, I can understand, I mean, he did just shoot your boyfriend... in your living room... to death. Alright, I'll give you that.

Ziva: I was wrong about Ari. And you. When I pulled the trigger, to save your life, I was not 'following orders.' I mean, how could you even think ... He was my brother. And now he is gone. Eli is all but dead to me. And the closest thing I have ... to a father...is accusing me...
Gibbs: OK.

One body isn't enough for you, tough guy? Because if it isn't, I've got three more right here!

Gibbs

Tony: He's got another one.
McGee: Well, that's great, but without cell's numbers, we can't track it." Tony: THINK, McSidekick! Use the leading man! Harness those powers!
McGee: It was an unregistered phone. It was pricey for a cop.
Tony: Bingo!
Gibbs: Shelley got it from a bust.

Gibbs: He said he was set up.
Ducky: His presence here would tend to confirm that. But set up by whom? Gibbs: Someone from his past ...
Ducky: ... making it appear that he stalked and murdered his tormentors.

Tony: How long have you been standing there?
Ziva: Long enough to see that you are well-hydrated after your time in the desert.

NCIS Season 7 Quotes

Salim: So what are you doing here?
Tony: There's only one force on Earth that can short circuit a man's better instincts, put fire in his veins and make him dive head-long into danger without regard for his well being. Vengeance. I'm here to kill you.

Salim: DiNozzo. It's an Italian name.
Tony: An educated man.
Salim: I got my B.S. from Yale University.
Tony: [scoffs] I got my B.S. in the streets ... You guys got a lousy football team.
