This man sets up a social experiment to see what would happen if he dropped $20 on the floor out in public. These people do something that shocked him.
Originally thinking, "would these people run off with my money or return it?" He then picks 10 people to walk by in public, and it just so happens that each and every one of those people return the $20 back to him. To reward them, this man tells them "thank you" and actually lets them keep the money he dropped, just for doing this good deed. He admits that his faith in humanity has grown immensely by doing this.
