Five Englishmen in an Audi Quatro arrived at an Italian border checkpoint.

Mario (the officer) stops them and tells them, “It is illegal to put 5 people in a Quatro - Quatro means four”.

“Quatro is just the name of the automobile,” one Englishman retorts disbelievingly. “Look at the papers: this car is designed to carry five persons.”

“You can not pull that one on me,” replies Mario. “Quatro means four. You have five people in your car and you are therefore breaking the law.”

The Englishman replies angrily, “You moroff. Call your supervisor over - I want to speak to someone with more intelligence!”

“Sorry,” responds Mario, “Luigi is busy with 5 guys in a Fiat Uno”.
