I don't normally have a very ribald sense of humour, but this made me chuckle:
Isabella* could well have listened to the tales of Jean de Condé, poet in her in her lifetime at her mother's native court in Hainault. His style is illustrated by a story about a game of truth-telling played at court before a tournament. A knight asked by the queen if he has fathered any children is forced to admit he has not. And indeed he did not have the look of a man who could please his mistress when he held her naked in his arms for his beard was little more than the kind of fuzz that ladies have in certain places. The queen tells him she does not doubt his word for it is easy to judge from the state of the hay whether the pitchfork is any good.
In his turn the knight asks, "Lady answer me without deceit, is there hair between your legs?" When she replies, "None at all," he comments, "Indeed I do believe you for grass does not grow on a well-beaten path."
*Isabella: eldest daughter of King Edward III and Queen Philippa
Also, so far I kind of love Isabella. She was spurned at the altar, then jilted a fiancé in her turn while keeping the money awarded to her as income by her father the king.
