Tony: Open and shut case, Boss.
Gibbs: No such thing, DiNozzo. Only water-tight.

McGee: That's pretty clever, Boss. How'd you figure that out?
Gibbs: Too much time around you.

Gibbs: How is he?
EMT: He'll live.
Tony: Well I've been hit harder, Boss...by you.

(Gibbs takes a call from the Director)
Tony: Jenny?
Gibbs: Jenny? Just, ah, how cozy did you two get while I was away?
Tony: (laughs) Boy that knock to the head must have been harder than I thought, 'cause I'm saying crazy things I don't even understand... (nods towards EMT) You think she's single?
Gibbs: (to EMT, nodding) He's fine.

Mike: Where'd you learn to be such a pain in the ass.
Gibbs: Working with you.

(After a threat is made on Mike's life)
Gibbs: I want a 24-hour protection detail. DiNozzo, you're team leader.
Tony: You're in safe hands, Mike.
Mike: I've seen your hands, DiNozzo. They don't impress me. (To Gibbs) I don't need babysitting, Gunny. I can look after myself.
Gibbs: After spending 4 months in that crap-hole you call a home in Baja, I find that highly debatable.
Tony: Safe-house, Boss?
Gibbs: Yup. Mine. Make yourself at home, Tony.
Tony: I won't touch a thing, Boss.
