Five Englishmen in an Audi Quattro arrive 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 car," the Englishman retorts disbelievingly. "Look at the papers. The car is designed to carry five people."
"You can't pull that one on me," replied Paddy. "Quattro means four, you have five people in your car and therefore you are breaking the law."
The Englishman replies angrily, "You idiot! 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."
