the italian customs agent stops them and says, "it's illegal to put five people in a Quattro."
"what do you mean it's illegal?" ask the englishmen. "Quattro means 'four'" replies the officer.
"Quattro is just the name of the automobile!" the englishmen retort with disbelief. "look at the papers: this car is designed to carry five persons."
"you can't pull that one on me-" replies the italian customs agent. "Quattro means four. you have five people in your car and you are therefore in violation of italian road laws."
the englishman driving the car loses his temper and exclaims "you idiot! call your supervisor over, i want to speak to someone with more intelligence!"
the agent looks over his shoulder behind him and says, "he can't. he's busy with two guys over there in a Fiat Uno."
