Sales Dogs

There was a hound dog laying in the yard. An old man in overalls was sitting on the porch.

"Excuse me, Sir, but does your dog bite?", the visiting salesman asked.

The old man replied, "Nope."

So the salesman stepped out of his car. The dog ran over snarling and growling and bit him on his arms and legs.

As the dog was dragging him away, the salesman was flailing around in the dust and yelled, "I thought you said your dog didn’t bite!"

The old man replied, "Ain’t my dog."
