A Very Patient Pooch

There was a barber in a developing country who had a little shed at the roadside to cut hair, and a certain man used to come in regularly for haircuts. One day he noticed that a dog was always sitting underneath, near the chair where the customers sat for their haircuts. So the man asked the barber, "Is that your dog?" And the barber replied, "No, he always comes every day. It's not my dog. I don't know whose dog it is." Then the customer asked, "So if it's not your dog, you never feed him, right?" And the barber said, "No." And the customer said, "Then why does he always come here every day?" And the barber answered, "He's waiting in case an ear comes off." A Very Patient Pooch.
