A traveling salesman pulls up to an old farmhouse, where he sees an ole gentleman sitting on the porch, silently rocking.
A large dog is lying in the yard.
The salesman rolls his window down and hollers, WILL YOUR DOG BITE?
NOPE, says the ole farmer.
The salesman gets out, and the dog jumps him.
After quite a tussle, the salesman finally makes it back to his car. I THOUGHT YOUR DOG WOULDN’T BITE.
The ole farmer says, AIN’T MY DOG.
