Once alone, the four begin their binge. In one scene, Marcello and Ugo race each other to see who can eat oysters faster. They discuss organizing a little "feminine presence" and decide to invite three prostitutes to come to the house the following evening (not four, because Philippe does not want to participate). Their breakfast next day is interrupted by the arrival of a school class who would like to visit the garden of the villa to see the famous "lime-tree of Boileau", under which the French poet used to sit while looking for inspiration. The four willingly invite the class not only into the garden, but also to view the old Bugatti in the garage and to a magnificent lunch in the kitchen. Above all, they get to know Andrea, the young and buxom teacher, whom they spontaneously invite to dinner that evening. Philippe is dismayed at the notion of the school teacher being in the same company as three prostitutes; he warns her, but she appears not to be perturbed. The prostitutes arrive in due course and the atmosphere becomes frivolous and sexually charged, with each of the men howling throughout the film when they are overjoyed. Andrea arrives and embraces the spirit of the party. She is attracted to Philippe, who proposes to marry her.
