Called his horse

Anthony drove his car into a ditch in a desolated area. A local farmer, Terry, came to help with his big strong horse named Yogy. He hitched his horse up to the car and yelled: Pull, Stapy, pull! Yogy didn't move. Then the farmer hollered: Pull, Grommy, pull! The horse didn't respond. Once more the farmer
commanded: Pull, Troly, pull! Nothing. Then the farmer nonchalantly said: Pull, Yoggy, pull! And the horse easily dragged the car out of the ditch. Anthony was most appreciative and very curious. He asked the farmer why he called his horse by the wrong name three times. Well, Yoggy is blind and if he thought he was the only one pulling, he wouldn't even try, said the farmer.
