De Bérangier au lonc cul: "De Bérangier au lonc cul" is a medieval French fabliau.  There are two versions of the fabliau: one by Guerin and one anonymous.  In summary, the story begins when a rich earl marries his daughter off to a "young peasant" and deems him a knight.  The knight abandons the code of chivalry and lazes around for the first ten years of the marriage.  When his wife, tired of his demeaning attitude and lazy nature, speaks of the greatness of the knights in her family, the husband decides to prove himself a worthy knight.  He dresses in armor and goes into the forest on horseback.  Once in the forest, he hangs his shield on the lowest branch of a tree and beats it until it looks as if it endured a great battle.  The knight returns to his wife, shows her his bruised armor, and gloats about his victories.  After a few trips into the forest, the wife begins to wonder why the knight himself is unscathed while his armor is in shambles.  The next day, she suggests he take servants with him.  When he refuses, the lady dresses in a full body suit of armor and follows him into the forest.  When she sees him beating his own shield, she steps into sight and threatens to kill him for his dishonor to chivalry.  The knight does not recognize his wife's voice.  He begs for "pity" and offers to do anything to avoid conflict.  His wife, disguised as a mighty knight, gives him the option of jousting her, in which he will surely die, or kissing her arse.  Out of cowardice, the knight chooses to kiss her arse.  She hops off her horse and pulls down her pants.  While the knight should have recognized her female genitalia, he remarks that she has a long arse.  Before she leaves, she tells him, "I'm Bérangier of the Long Ass, Who puts shame to the chickenhearted."  The wife returns home and sleeps with a valiant knight.  When her husband arrives from the forest, he rebukes her.  However, that was his last demeaning remark to her.  She tells him she met Bérangier and learned of her husband's cowardice.  To protect his own name, the knight is forced to succumb to his wife's wishes.  Her cleverness leads her to do as she pleased for the rest of her life, and her husband lives in shame.
