In the irreverent comedy Monty Python and the Holy Grail, which is a send up of the King Arthur tales, there is a scene where one of the knights, Sir Bedevere is confronted by a group of villagers. It seems they have gripped one of the local women and claim she is a witch. It's very obvious that her long crooked nose is fake and has been tied on and she's been dressed up to look like a witch. Sir Bedevere questions the evidence and the people confess that they made it all up. But they still want to burn the woman as a witch.
