Season 4, Episode 5: "The Wallet"

Oh, hey, by the way...

...do you want a box of Cuban cigars?

I smoked one last night. I got nauseous.

No, I don't want them.

I'll take it. No, I'll take it. What is it?

-Here you go. -What, cigars?

-Yeah, Cubans. -Oh, yeah?

Yeah, the kind that Castro smoked. You can't buy them anywhere.
