While Arianna (Jessica Barlacchi) is swimming she is stung by a jellyfish, a girl (Giordana Beretta) says she has an ointment but in exchange she wants a kiss from Martino (Elia Scolari).
in a comical scene the children run out of school, the boys naked (many cover their private parts with their hand) and the girls topless,then they return to class to get dressed after being scolded by an embarrassed teacher.
