Excuses, Excuses

Mike spent all his money on a sleek new Mercedes roadster and was out on the motorway for an evening cruise. The top was down, the breeze was blowing through his hair and he decided to open her up. As the needle jumped up to 80mph, he suddenly saw a flashing red and blue light behind him.
'There's no way they can catch me,' he thought to himself and opened her up further. The needle hit 130, with the lights still behind him. 'What on earth am I doing?' he thought and pulled over. The cop came up to him, took his licence and examined it. 'Listen mate,' said the cop. 'I've had a tough shift and this is my last pull over. 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!
'Last week my wife ran off with a cop,' the man said, 'and I was afraid you were trying to give her back!'
'Have a nice night', said the officer.
