“In the countryside, a guy’s car gets stuck in a muddy rut. Fortunately, a farmer is just walking
his strong-looking shire horse past. “Don’t worry, there,” says the farmer, hitching the horse to
the car. “Soon have you out.” Then he calls out to the horse “Pull, Dobbin!” But the horse
doesn’t budge, so he tells it “Pull, Barney!” Still no response, so he says “Pull, Harry!” and this
time, the horse gives an almighty tug and the car comes free. “That’s great, thanks very much,”
says the driver, and then asks “Couldn’t you remember his name or something?” “No, it’s just
that Harry’s blind,” says the farmer. “He wouldn’t bother trying if he thought he was the only one
pulling.””
