Kate McClure ran out of gas on a dark night on a New Jersey highway. She was walking to find a gas station when a nearby homeless man named "Johnny" told her to get back into the car, lock the doors and he would do it for her. He spent his last $20 on the gas. She could not repay him at the time. BUT she set up a GoFundMePage planning to collect $10,000 in donations to give him. So far it is in excess of $300,000! He cast his $20 upon the waters and that's what came back to him. I warned you the story had a happy ending. :)
