There is a discrepancy in the punishment wheel. When the " wheel of punishment" is brought out to determine Aang's fate, it lands on "boiled in oil." Look at the square next to it, it looks like a person on a bed of nails.
Later on when the Rough Rhino's attack, the wheel is moved ahead 1 square to land on "community service". The "bed of nails" was moved to be after community service.
