Go to a local dollar store or any other place and find a fake $50 or any other amount bill. Place a string that is see-through around it or through one of the corners. Go to a busy public place where you can hide behind a bush and stick the dollar out where someone could see it. When people walk by and are just about to reach for the dollar pull it in behind the bush without showing yourself! Great if you have a friend with you, you will have lots of laughs.
