Long time ago, we drove to Italy, and someone joked that he wanted to meet that miss Caduta Massi, whose name was written on so many road signs. It became a running gag during a great holiday: we praised the paintings of Vietato Fumare in the Roman museum of contemporary art, asked directions to the home of Senso Unico, and were happy when A.S. Roma finally bought a new striker, Totò Calcio.
Some time ago, I was in the Louvre to take photos of Roman portrait busts, when a Dutch tour guide parked her group next to me, had a quick look at the explanatory sign, and asked attention for the bust of the Emperor Inconnus. Unfortunately, that was not a joke.
