On the border of Kentucky and Tennessee there's a small forest. Half of the forest belongs to a Kentucky farmer, while the other half belongs to a Tennessee man.

One day, while out for a walk in the woods, the Tennessee man comes across a wolf caught in a trap. He rushes back to his house and calls his Kentucky neighbor.

"There's one of your wolves caught in a trap on my side of the forest."

"How do you know it's one of *our* wolves?" the Kentucky farmer asked.

"Well," the Tennessee man replied, "he's already chewed off three of his legs and he's still trapped."
