Middle ages jester?

In the Middle Ages people began to train as fools. Known as Court Jesters, these people entertained royalty with their antics. In addition to the usual slapstick and other types of humor, jesters developed the art of satire and, using satire, were able to get away with mocking people and institutions in ways that, if they had been ordinary people saying or doing such things, would have been thrown into jail or worse.
