Chain letters were a thing when I was a kid 30 years ago. You were supposed to send a dollar to the person a the top of a list of like 4 people, then move everyone up one spot on the list and and put your name at the bottom and send it to 10 people with the same instructions. If everyone did it, you would end up receiving $10,000. Of course, some simple math will tell you that you will run out of people in the world very quickly. People love free money and are bad at math.
