"Carlo Martello ritorna dalla battaglia di Poiters (Carlo Martello Returns from the Battle of Poiters) came about in a curious way. In one room, Mauro De André, Fabrizio's older brother, was preparing for his civil procedure exam, while in the next room, Paolo Villaggio and Fabrizio were helping each other with their private law exam. After a month, Mauro passed the exam with flying colors, a milestone in a journey that led him to become a distinguished lawyer. Fabrizio and Villaggio, on the other hand, composed a pleasant and playful song about Carlo Martello and another entitled Il fannullone (The Slacker). They did not take the exam and never graduated."
