Religious Horse (Joke)?

One day a farmer's favorite horse died. After mourning for several days he decides he wants a new horse. Being very religious he decides he wants a religious horse. He prays for weeks and weeks for a religious horse. One day as he walked to town, he saw the local horse salesman advertising that he had a religious horse for sale. The farmer immediately buys the horse, and is told that the horse will only start when someone yells "Praise the Lord" and it will only stop when someone yells "Amen". The farmer decides to take him for a ride down the street. He gets on and yells "Praise the Lord" and the horse starts galloping. The farmer is having so much fun he doesnt realize the horse has gone off the road until he is headed strait fo a cliff. The farmer forgets how to stop him so he begins praying. Just as he says "Amen" the hose stops, just cenimeters away from the edge of the cliff. Then the farmer, glad he was saved from going off the cliff yells "Praise the Lord"
