The Lost Order was the command that would cause clone troopers to track down and kill every goddam Ewok left in the universe without stopping to eat, shit or even pick their noses. It is called the Lost Order because some senile, decrepit, old fart conveniently forgot the order before the battle of Endor and ended up losing the whole empire as well. Of course in an attempt to find the order, he rattled several others off which resulted in random and massive violence- so, hey! Not a total loss!
