I'd like some crackers to go with the cheese

I was just walking the dog and had the following coversation:

Guy: Your dog is beautiful.
Me: Thank you.
Guy: Just like his owner.
Me: Thank you.
Guy: Are you from Tennessee?
Me: No.
Guy: Well, you're the only ten I see.
Me: I'm married, okay?

Really, really, really never ever thought anyone ever used that line in real life. How often does he get anywhere with it?
