Imagine finding a huge wad of cash just sitting there with nobody around to claim it. Do you keep it, hand it in or try to track down the mystery owner? We debate what you should do when you stumble across found money, whether honesty really is the best policy and how much cash it would take before you started questioning your morals. What would you do if you suddenly came into some unexpected money like this man in Japan. It's a very sad story that has a sadder ending.
