### The key

All the good knights were leaving for the Crusades. One knight told his best friend "My bride is without doubt one of the most beautiful women in the world. It would be a terrible waste if no man could have her. Therefore, as my best and most trusted friend, I am leaving you the key to her chastity belt to use should I not return from the Crusade in seven years."
