A beggar came to the farmers market, and a small group of people threw a few coins into his bowl. But most people didn't give him anything. He wrote down all the addresses of those who gave him money.

A few hours later, a Rolls-Royce pulled up in front of him. He went door-to-door returning money—ten times what he received. Everyone at the market was stunned.

The next day, he came back, and suddenly everyone at the market started giving him money. Almost everyone gave thousands or tens of thousands, with their addresses written on the back of the bills.

In less than 3 hours, the beggar had collected tens of millions.

Later, the beggar left and never came back.
