An out-of-towner accidentally drives his car into a deep ditch on
 the side of a country road.
 
 Luckily a farmer happened by with his big old horse named Benny.
 The man asked for help. The farmer said Benny could pull his car
 out. So he backed Benny up and hitched Benny to the man's car
 bumper.
 
 Then he yelled, "Pull, Nellie, pull." Benny didn't move. Then he
 yelled, "Come on, pull Ranger." Still, Benny didn't move. Then he
 yelled really loud, "Now pull, Fred, pull hard." Benny just stood.
 
 Then the farmer nonchalantly said, "Okay, Benny, pull." Benny
 pulled the car out of the ditch.
 
 The man was very appreciative but curious. He asked the farmer why
 he called his horse by the wrong name three times.
 
 The farmersaid, "Oh, Benny is blind, and if he thought he was the
 only one pulling he wouldn't even try."
