Quinn: I mean, maybe it's a coincidence. [McGee and Gibbs give her a look.] Oh, oh, no. Nope. Rule 69. "No coincidences."
McGee: No, actually Number 69 is "Never trust a woman who doesn't trust her man."
Quinn: Huh? Wait, what?! Really? That... sounds a little misogynistic, don't you think? Huh? I mean, do you have a rule that says "Never trust a man who doesn't trust his woman"? Think about it! Huh? No? Think about it! Rule 51!
McGee [to Gibbs]: "Sometimes you're wrong"! [Gibbs smacks the back of McGee's head.]
