One day while he was at the track betting on the ponies and nearly losing his shirt, Mitch noticed a priest who stepped out onto the track and blessed the forehead of one of the horses lining up for the 4th race.
Lo and behold, that horse -- a very long shot -- won the race.
Before the following race, the Priest blessed yet another horse. Mitch made a beeline for the window, and placed a small bet on the horse. Again, even though it was another long shot, the horse the priest had blessed won the race.
Mitch collected his winnings, and anxiously waited to see which horse the priest would bless for the 6th race. The priest showed, blessed a horse, Mitch bet a large amount of money on it, and it won!
True to his pattern, the priest stepped out onto the track before the last race and blessed the forehead, eyes, ears, and hooves of one of the horses.
Mitch bet every cent he had, including his life savings and the deed to his house. Mitch then watched the horse come in dead last. He was dumbfounded.
He made his way to the track, and when he found the priest, he demanded, "What happened, Father? All day long you blessed horses and they won. The last race, you blessed a horse and he lost. Now, thanks to you, I've lost all my savings!"
