Tony: Aha! My dynamic duo! Does anyone know where I can find Gibbs?
McGee: Uh... I think he's still in the conference room. What do you got?
Tony: (singing) I know... where Kaplan got the monnnneyyy...
McGee: Can't you try telling us like a normal human being?
Tony: Oh. All the funds are from the Broussard Bank in Geneva, Switzerland.
McGee: Whose account?
Tony: I don't know yet. But I'm going to find out! See ya!
McGee: We have got to keep him away from that new coffee machine.
McGee: Drew Turner?
Tony: You're a woman.
Mrs. Roach: (After NCIS prepares to investigate her tenant's apartment) Let's just get this over with. I'm missing Judge Judy.
Abby: (While talking to her elderly aunt on the phone) No, no, I'm not a cheerleader anymore... I graduated high school a long time ago...
Sportelli: (After seeing Tony flat down against the wall, with outstretched arms) What the hell is DiNozzo doing?
Gibbs: I... don't know.
Abby: I'm adopted Gibbs... I'm like little orphan Abby.
Sportelli: Fake suicide. Fake names. Women pretending to be men. This is getting messy.
Tony: (After Sportelli informs NCIS that he caught a contract killer, who has just been hit by a car) Great work, Detective Sportelli. You arrested the unconscious man! Did you have to cuff him when he was down on the sidewalk?
Lt. Geoffery: How did someone who looks like you become an NCIS agent?
Ziva: What are our agents supposed to look like?
Lt. Geoffery: Stern... Surly... Humorless... Agent Gibbs.
Tony: (after the silver haired manageress ogles Gibbs, then leaves the apartment) That's what they call a 'turkey vulture'. Twenty years past a 'cougar', still likes to hunt, but too old to take down the prey.
Mrs Roach: (proving her hearing is still impeccable) I wouldn't bet on that!
Gibbs: Family's more than just... DNA. It's about.. people who care and take care of each other.
