Grass Houses

There once was a king who lived in two-story grass hut. Every holiday the king demanded to be given a new throne as a gift. As soon as a new throne arrived, he would store the old throne on the second level of his hut and use the new one instead. But one day the hut collapsed from the weight of all the thrones, and everyone was crushed and killed.

The moral of this story? Those who live in grass houses shouldn't stow thrones.
