I remember many many years ago a game with a minor stock market element, where you could manipulate the market simply by increasing the dividend of a company you owned to an absurd amount. The share price would skyrocket, you could then sell it short, and as soon as the dividend was paid the company would be broke and the price would go to zero. Or something like that. The details are not the point, the point is it had a simplistic model that was extremely easy to exploit, and surely nobody would be dumb enough to think that is how reality works.
