Five Scotsmen in an Audi Quattro arrived at an Irish border checkpoint. Paddy the officer stops them and tells them: "It is illegal to put 5 people in a Quattro, Quattro means four."
"Quattro is just the name of the automobile," the Scotsmen retort in disbelief. "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."
The Scotsmen reply angrily, "You idiot! Call your supervisor over. I want to speak to someone with more intelligence!"
"Sorry," responds Paddy, "Murphy is busy with 2 guys in a Fiat Uno."
