Someone should make a one-off machine "Pump-n-Dump"... it would be a pinball machine about flipping undesirable pinball machines. Multiball would consist of angry buyers, each ball representing an angry buyer (a mob of angry buyers!) Jackpot would consist of locking each of the angry buyers (ball) into a "room" (ball lock) with one of the TNT sales guys or something.
This would be the most underrated game ever.
