Once upon a time, there was a kingdom which was ruled by a very wise king. One day, someone poisoned all of the kingdom’s water supply with something that made everyone go mad overnight. Everyone, that is, except the king, because he hadn’t drunk any water. When the king awoke in the morning, everyone was worried about the king’s mental health, and so, being a wise man, he did the only thing he reasonably could: he drank the water, and became as mad as the rest of them. Then everyone rejoiced because the king, in their eyes, had regained his sanity.
