Now, in the good old days, when knights were proud and brave, a knight would go off to join the Crusade. This knight called upon his esquire, "I am joining the Crusade. Here is the key to my wife's chastity belt. If I have not returned in 10 years, you can use the key."

The knight started his journey along the dusty road, wearing armor from head to toe. He gave his castle one last glance before it disappeared in the distance. Suddenly, he saw his esquire running toward him.

Out of breath, the esquire said, "Oh, sir ... it is a good thing I caught up with you in time. You have given us the wrong key!"
