A cute touch lost on non-Italians

At one point the camera picks up the sign "Livorno", and, below it, a fan of Livorno's soccer team has spray painted: "Zona Depisanizzata"--which means:
"Territory rid of Pisans" You see, the Livornesi hate the Pisani, though the Pisani could care less because they save their hatred for the Florentines. Famous Florentine saying: "Meglio un morto in casa che un pisano all'uscio" ("Better a dead person in the house than a Pisan at the door.")
