"Good Excuse" joke

A
man bought a new Mercedes to celebrate his wife leaving
him and was out on the interstate for a nice evening
drive.
The top was down, the breeze was blowing through
what was left of his hair and he decided to open her
up. As the needle jumped up to 80 mph, he suddenly
saw flashing red and blue lights behind him.
"There's no way they can catch a Mercedes,"
he thought to himself and opened her up further. The
needle hit 90, 100... Then the reality of the situation
hit him. "What 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 hard day, this is the end
of my shift and it's Friday the 13th. I don't feel
like more paperwork, I don't need the frustration
or the overtime, so if you can give me a really good
excuse for your driving that I haven't heard before,
you can go."
The guy thinks about it for a second and says, "Last
week my nagging wife ran off with a cop. I was afraid
you were trying to give her back!"
"Have a nice weekend," said the officer.
