Ziva: So you two did end up going out last night

Tony: How'd you know about that?

Ziva: I have hearing like a horse

McGee:  Hawk.

Ziva: A horse's hearing, McGee, is one of their keenest senses.  Which is why you must horse whisper.

McGee: I don't think that's right.

McGee:  I've never seen you take this long to close a deal.

Ziva: Rent a room already!

Tony: Get! It's get a room. And I would have already if I didn't have two player-haters chiming in from the cheap seats.
