NCIS, Season 8

Tony:
Salads are not stakeout food.

Ziva:
Well, they should be. [motioning at his sandwich] At least they don't stink up the car.

Tony:
[offers an onion ring] Want one?

Ziva:
No!

Tony:
Your loss.

Ziva:
Did Gibbs say anything to you about Agent Barrett? You know, dating?

Tony:
No.

Ziva:
[sighs] Are you sure he knows?

Tony:
He's Gibbs. He knows everything. He did read her the riot act, though.

Ziva:
Well, that's not good, Tony. I mean, you should talk to Gibbs. You and him go way back! I mean, it's like the big rhinoceros in the room that no one wants to talk about.

Tony:
Elephant.

Ziva:
Huh?

Tony:
It's an elephant in the room. It's not a hippopotamus, it's not a rhinoceros. It's an elephant.
