An American tourist arrived in Rome and boarded a taxi to tour the city.
The driver then took him to the front of the famous Colosseum.
Surprised, the tourist asked what it was, and the driver proudly said that it was the Colosseum.
The tourist then asked the driver how long it took to build it, and the driver replied that it might have taken a few years.
On hearing that, the tourist smiled and said that it would only take a year to build the Colosseum in America.
Their next stop was the Pantheon. The surprised tourist then asked what it was and how long it took to build it.
The taxi driver noted that it was the Pantheon, and it took about a year to build it.
The tourist then replied mockingly, “Ah, in America we can build it in just one month!”
So, the taxi driver became nervous but continued to drive the tourist around town.
Finally, he drove him to the front of San Pietro in Vatican City.
The tourist asked him what it was, and the driver said, “I do not know. Yesterday it was not there!”
