While the portions of Monty Python and the Holy Grail showing the French abusing the English are funny, they also seem a little over the top. Then you read something like the Gesta Herewardi where the Normans hire a witch to put a curse on the besieged at Ely. As the hag stands on top of a wooden structure so she can see and be seen, she hurls abuse and incantations and then she turns around to finish the job by baring her behind at the defenders. Yes, the witch mooned Hereward. Take that!
