Do unto others as you would have others do unto you.

Never has that old adage been more literally on the money than in the case of Billy Ray Harris, a homeless man in Kansas City, Missouri who returned a diamond ring to a woman who accidentally dropped it in his coin cup when she gave him some cash.

Harris returned the ring to the woman and now people from all over are coming together to help him out.

Sarah Darling was being a Good Samaritan when she decided to give Harris some change. However, she didn’t realize until later she dropped her ring in Harris’ cup. A few days later, she found Harris, who said he had held onto the ring and gave it back to her, no questions asked. Darling and her husband were so touched they set up a website where people could donate money to Harris.

The site has taken off, with more than $150,000 in donations coming in so far, providing Harris 15 minutes of fame and enough cash to maybe even buy a whole hour.

Harris has taken his good fortune in stride, saying, "I like it, but I don't think I deserve it. What I actually feel like is, 'what has the world come to when a person who returns something that doesn't belong to him and all this happens?'"

Here’s hoping Harris' story has a happy ending, much like another homeless man who had a surprising rise to fame.
