There was this preacher who decided to sell his horse. A prospective buyer was impressed with the animal, but the preacher said, "I must warn you - he only reponds to 'church talk'. Go is 'Praise the Lord', and stop is 'Hallelujah'." "I've worked with horses all my life," said the buyer, "and I've never heard of anything like this." Mounting the horse, he said skeptically, "Praise the Lord." The horse began to trot. He repeated "Praise the Lord" and the horse broke in to a gallop. Suddenly the buyer saw a cliff dead ahead. Frantic, he yelled "Hallelujah," and they came to a stop a foot from the edge. Wiping the sweat from his brow, the buyer said, "Praise the Lord!"
