Part II. A Joke     
A man in his 40s bought a new BMW and was out driving on the interstate (州際公路) at top
speed when he suddenly saw flashing red and blue lights behind him.
"There's no way they can catch a BMW," he thought to himself and sped up even more. Then
the reality of the situation hit him, "What the heck (搞什麼鬼) am I doing?" he thought and pulled over.
The cop came up to him, took his license without a word, and examined it and the car. "It's been a
long day, it is the end of my shift (輪班), and it's Friday the 13th. I don't feel like more paperwork,
so if you can give me an excuse for your driving that I haven't heard before, you can go."
The guy thinks for a second and says, "Last week my wife ran off with a cop. I was afraid you were
trying to give her back."
"Have a nice weekend," said the officer.
