A poem, recited at the Book & Wine event, Budapest 2016, following a Summary of the 15th Century French play, La Farce de Maître Pathelin, which led to a French idiom, "revenons à nos mouton", and  an English idiom,"Let's return to our muttons",meaning, let's return to a given topic or subject that one is discussing

Here's the summary of the play.

Master Pierre Pathelin is a local village lawyer with no professional, formal training who has very little work, due to the emerging class of professionally trained clerks and lawyers. In order to obtain cloth to replace his and his wife's holey clothing, he visits the clothier Guillaume Joceaulme. By flattering him, Pathelin convinces the clothier — against his better judgment — to let him have six yards of fine cloth on credit. However, he promises Joceaulme that he can visit his house that day to be paid.

When Pathelin arrives home he tells his wife Guillemette that the clothier is due to arrive home and to pretend that Pathelin has been sick in bed for almost three months. After some humorous arguments, Joceaulme barges in on Pathelin, who is in bed and raving like a madman. In time Pathelin's entertaining babble moves from one French dialect to another, which Guillemette has to explain away.

After Joceaulme gives up on attempting to retrieve his payment, he turns his thoughts to his shepherd, Thibault l’Aignelet, who has been stealing Joceaulme's sheep and eating them for the past three years. Joceaulme summons Aignelet to court, and the latter goes to Pathelin in order to be legally represented. Pathelin directs Aignelet to say only "Baaa" (like a sheep) when anyone questions him in court in the hope that the judge will find Joceaulme's case groundless, as it will appear that he has taken a mentally-challenged person to court.

 

At the trial Joceaulme instantly recognizes Pathelin. He tries to explain the details of both cases (the stolen cloth and the stolen sheep) to the judge, but he is unable to do so clearly, and the judge conflates the two cases. Because of Joceaulme's incoherent case against the shepherd (and the latter's one word nonsense response of "Baaa"), the judge rules against him. Pathelin attempts to collect his fee from Aignelet, but the latter only answers Pathelin's demands with "Baaa." Pathelin realizes that his brilliant defense is now being used against him, and he goes home.
