Bad Harry was looking for sharp businessmen who could buy his very expensive snake oil, consume it, and find other people who could do the same. You find 6 people and they find 6 people and they find 6 people and so on and so on.
It was very difficult to claw their way up the pyramid.
Finally someone figured out the truth. Even though they might find a few customers to buy snake oil eventually these customers would go to another store where they could buy the snake oil for so much cheaper. The sad reality was customers were hard to find and even harder to keep around. Then they found out that the snake oil cost one tenth the price they were selling it for. Someone was getting rich and it was not the downline.
Yes this is what one can come up with after a few pina coladas!
