Milk bottle joint: If it's honest, the bottles, though heavier than real ones would be are all the same.
If the joint is grifted three are extra heavy, three are lighter.
Put the heavy bottle on top of the pyramid and let your shill throw the ball, even he lightest hit will knock them over.
Put the heavy ones on the bottom row of the pyramid, even a major league pitcher would have trouble knocling them over.
