An out-of-towner drove his car into a ditch in a very rural area.
Luckily, Farmer Jones came to help with his big strong horse named
Hobo . . .

He hitched ole Hobo up to the car and yelled, "Pull, Nellie, pull!"
Hobo didn't move a muscle... just flicked away a fly with his tail.
Then Jones hollered out, "C'mon, pull, Davey, pull!" Again, ole Hobo
didn't move. Once more the farmer commanded, "Pull, Stetson, pull!"
Nothing from Hobo. Then the farmer nonchalantly said, "Pull, Hobo.
C'mon, boy, pull!" And the horse easily dragged the car up, out of
the ditch.

The motorist was most appreciative and very curious. He asked the
farmer why he called his horse by the wrong name three times in a row.
Wise Farmer Jones answered, "Well, ole, Hobo here is blind as a bat.
If he thought he was the only one pulling, he wouldn't even try!"
