They're in the state of Tennessee, and stop at their friend, Corky's to sell him some Ford signs. When they make the deal and the signs are unloaded, they end the program with this:
Corky: "Let me tell you, when you come back to Tennessee, you gotta call ahead of time and I'll go out and get a fresh possum off the road for you and we'll have a barbeque."
Corky: "Promise you, next time!"
Mike: (Shakes hands and says) "Thanks!"
