(I didn't see one of these already when I looked through this forum.)
Basically, the person above you will make a wish. You grant it yet find someway to make it corrupt.
Example: I wish I had a million dollars.
Granted, but it's all in pennies and you can't exchange them for larger bills.
So on and so forth. Once you corrupt someone else's wish, then you make your own for the next person to corrupt.
I wish the next four months would hurry up and be over with.
