A man was driving into town, and he fell in a big ditch in the middle of the road.
A farmer came up and said, "My horse Sebastian can pull you out," the man said OK and the farmer got Sebastian.
When Sebastian was hooked up, the farmer said, "Pull Ranger! C’mon Benny! Lets go Delilah!!!!" Then the farmer said, "Pull Sebastian, pull!"
Then the car was out of the ditch, the man said, "I have a question, why did you say the wrong name three times?"
And the farmer said, "Because Sebastian is blind, if he knew other horses weren’t pulling, he wouldn’t even try..."
