A Rabbi is walking slowly down the street when a gust of wind blows his hat from his head. The hat is being blown down the street, but he is an old man and can't walk fast enough to catch the hat. Across the street a Gentile sees what has happened and rushes over to grab the hat and then returns it to the Rabbi.
"I don't think I would have been able to catch my hat," said the rabbi. "Thank you very much."
The rabbi then places his hand on the man's shoulder and says, "May God bless you."
The young man thinks to himself, "I've been blessed by the rabbi, this must be my lucky day!" So he goes to the racetrack and in the first race he sees there is a horse named Stetson at 20 to 1. He bets $50 and sure enough the horse comes in first.
