Tony: “Is that all you know? Ah, that’s all you can tell me. I got it. You know, in Arabic, the word for ‘desert’ is ‘sahara’, so ‘Sahara Desert’ is actually ‘desert desert’. A lot of sand.”

These two old warriors, they probably shot at each other on the battlefield. They couldn't even look at each other at their own kids’ wedding. But they did come to live with each other in the same house. And they spent every day for the rest of their lives on the front porch, in a couple of wicker rocking chairs, rocking back and forth.”
Vance: “Here’s hoping. We got better things to do than be the Franks’ family counselor. I guess they worked out their differences? Your relatives? They mellowed with time, right?”

Tony: “Are you gonna talk in metaphor for the rest of the round, sir? Cause, if so, I’m gonna need a few more beers.”
Ziva: “Well, I have put in some time for my vacation. You never know; maybe our paths will cross.”
Tony: “Ah, where are you going? You know, there’s a new app that tells you where every Cracker Barrel in the country is.”
