There was a man in town, they called him Schlmeil, which means one having no luck. 

He wasn’t a real bright guy to begin with, and he never seemed to be able to do anything right.

Yet, despite all that, he won the big lottery.

When the townspeople heard, they gathered around him.

"Tell us, what’s the secret of your success? You’ve never been a lucky person. You’re not a great intellectual. How did you figure out which numbers to play?"

Schlmeil explained.  "There are 24 hours a day, and 365 days of the year. I multiplied the two numbers and put my money on that number, and I’m a winner!"

"But the winning number was not equal to 24×365, which would be 8,760; it was 8759, one number off," said one of the men in the crowd. 

"Ah, yes!" said Schlmeil. "You all know I'm not so smart as to multiply correctly. That's how I finally got lucky!"

And from that day on, when his ineptitude came in handy, and his luck turned around, the lottery winner was re-named Schlmazel, which means one having good fortune, or some would say good luck.

After all, what's in a name, when God and chance are on your side?!!
