The Tribal Chief.

Once upon a time there was a chief of a small tribe in a village way out in the middle of nowhere in the middle of Africa.  The chief lived in a grand grass house and ruled benignly over his tribe.  He had an old throne carved from local stone and it had been in the family for many years.  One day a visiting chief brought him a gift of a brand new iron throne.  There was great celebration and the next day the chief installed the new throne and put the old one in the loft.  He was sitting quietly contemplating on his plush new throne when there was an almighty crash as the old throne fell through the roof and squashed the chief killing him dead on the spot.

The moral of the story:  Don't stow thrones in grass houses.
