Many years ago, a tiny island nation in the South Pacific was home to
some of the finest woodworkers who ever lived.  Unfortunately, no one
ever found out about these legendary artisans since the only pieces
they ever produced were thrones for the king of the island.  It was a
tradition that every year, on the first day of summer, the old throne
would be burned in a massive bonfire and the woodworkers would present
the king with their newest masterpiece, an ornate and beautiful throne
they spent all year carving and shaping.  The king would rule from the
new royal seat and then destroy it at the next year's summer festival.

One year, a new king ascended to the throne and spoke to his council
of elders.  "It's a foolish thing to take these beautiful pieces of
art and destroy them every year!  Someone should save them for future
generations to enjoy."

But one of his ministers quickly pointed out, "Sire, this is a small
island, and much of the land has been taken.  We have no room to build
a museum."

Thinking quickly, the king proposed a solution.  "I have the answer.
We will build a second story onto the royal hut, and we shall store
the thrones there."

The king's plan worked beautifully for a few years.  Every year, he
would summon the strongest men on the island to carry the thrones up
into the second floor of the royal hut and add them to the collection.
But on the fifth year, the floor finally could take no more, and the
royal hut collapsed, killing the king and his whole family.

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