Who is smoking a French cigarette?

M: (sniffing) Is that a French cigarette?
W: Pardon?
M: Is that a French cigarette you’re smoking?
W: Yes, that’s right. Why? What’s the matter?
M: I don’t understand why you smoke French cigarettes. They make a terrible smell.
W: I like them very much. I prefer them to English cigarettes.
M: Have you got a lot of them?
W: Yes, about 200, why?
M: Well... er... could I buy some from you?
W: Buy some from me? But... you don’t like French cigarettes!
M: No, I don’t. But my wife does.
