The cost of making only the maker knows,
Valueless if bought, but sometimes traded.
A poor man may give one as easily as a king.
When one is broken pain and deceit are assured.
In medieval England, a king's jester was imprisoned (the king didn't like the jester's jokes). The jester was locked in a room at the top of a high tower. The room had only one tiny window. The jester found a piece of rope. It wasn't long enough to reach the ground. So, he divided it in half and tied the two halves together. This made the rope long enough and he escaped. How?
