Old man and his BMW

A senior citizen drove his brand new BMW out the car sales room . Taking off down the motor-way , he floored it to 90 , enjoying the wind blowing through . Amazing he thought as he flew down the Motor Way, looking in his 
rear view mirror , he saw a 
police car behind him , blue light flashing , siren blaring . 
'' I can get away from him - no problem ! '' He floored it to130 , then 140 ...then 150 ... 
Suddenly, he thought , '' What on earth am I doing ? I'm too old for this nonsense !'' So he pulled over to the side of the road and waited for the police car to catch up with him . 
Pulling in behind him , the officer walked up to the driver's side of the BMW , looked at his watch and said, ''Sir , my shift ends in ten minutes , Today is Friday and I'm taking off for the weekend , If you can give mea reason I've never heard before for why you were speeding , I'll let you go '' 
The Man looked very seriously at the police man , and replied , '' Years ago , my wife ran off with a policeman , I thought you were bringing her back , '' 
The Cop left saying ''Have a good day , Sir....!!
