After Aang if found guilty of killing the village's leader many years ago, they bring out the Wheel of Punishment. They spin the wheel counter-clockwise and it lands on "Boiled in Oil". The picture on the right of "Boiled in Oil" is a guy LYING ON A BED OF NAILS. Then a bunch of fire-benders show up to raid the place. The judge asks for Aang's help, but he says he's going to be boiled in oil. The judge decides to turn the wheel one more to the left, putting the pointer on the picture to the right of "Boiled in Oil", which is now "COMMUNITY SERVICE". See for yourself! I guess the guys who do the drawing have an even shorter memory than I do.
