The Sordi episode of “Dove vai in vacanza” (“Vacanze intelligenti”) is one of the most hilarious Italian comedies ever made. The fabulous Anna Longhi plays Sordi’s fat wife. They are both Roman fruit vendors. Their snobbish children send them off on a vacation trip through Italy where the parents are supposed to get cultured and lose weight at the same time. But they are in turn puzzled, unhappy, and hungry. They long for their Roman sausage and pasta.
