Five Englishmen in an Audi Quattro arrived at an Irish border
checkpoint. Paddy, the officer, stops them and tells them: "It is
illegal to put five people in a Quattro. Quattro means four."
"Quattro is just the name of the automobile," the Englishman
retorted disbelievingly. "Look at the papers: this car is designed to
carry five persons."
"You cannot pull that one on me," replies Paddy. "Quattro means
four. You have five people in your car and you are therefore breaking
the law."
"You idiot!" the Englishmen replies angrily. "Call your supervisor over. I want to speak to someone with more intelligence!"
"Sorry," responds Paddy, "Murphy is busy with two guys in a Fiat Uno."
