A preacher was selling a horse. A cowboy decided to buy the horse. The preacher told the cowboy to make the horse go, to say 'Thank God' and to stop the horse, to say ' Hallelujah'. The cowboy then rode off into the sunset until he came upon a cliff, searching his memory he yelled hallelujah and the horse stopped just before going off the cliff. Then the cowboy said 'Thank God".
