A priest was walking, slowly, out of a church in London

A priest was walking, slowly, out of a church in London when a gust of wind blew his hat off and down the street. He was an old man, who walked with the aid of a cane, and who wasn't able to fetch his hat. Across the street, a young man saw what was happening, rushed over and grabbed the hat. He then returned it to the priest.

"I don't think I could have retrieved my hat by myself," the priest said. "Thank you very much!" He then placed his hand on the man's shoulder and said, "May God bless you."

"I've been blessed by the priest," the young man thought. "This must be my lucky day!"

Right then and there, he decided to go to the racetrack. In the first race he noted a horse named 'High Hat' at 20 to 1. He bet £50 and, sure enough, the horse came in first, netting him £1000. In the second race, a horse named 'Trilby' was at 30 to 1, so he bet all his money on it, and it came in first, as well. He continued like that for some time, betting on horses with hat names.

At the end of the day the man returned home to his wife. She asked him where he'd been, and he told her. 
"So where's the money?" she said. 
"I lost it all in the ninth race. I bet on a horse named Chateau and it lost." 
"You fool, 'chateau' is a house, 'chapeau' is a hat!" exlaimed his wife. 
"It doesn't matter," he said, "the winner was some Spanish horse named Zucchetto."
