Meg, hehe, Terry Pratchett has a story, although I haven't read it, but watched it in an animated version... so, there was a royal jester who became king at the end of the story) it's a long story, but the point is that jesters sometimes have more power than kings, and they know much more
anyway, there's another saying or proverb about the King and the Jester, but I don't remember it x
