Jester's privilege

Jester's privilege is the ability and right of a jester to talk and mock freely without being punished; for nothing he says seems to matter.

Martin Luther used jest in many of his criticisms against the Catholic Church. In the introduction to To the Christian Nobility of the German Nation he calls himself a court jester, and, later in text, he explicitly invokes the jester's privilege when saying that monks should break their chastity vows.
