a blond is speeding down the highway when she notices she is being pulled over by a police officer.  the police officer is also blond and female.
the blond police woman walks up to the blond drivers window and asked to see the drivers license. the blond driver starts to fumble frantically through her purse looking for her license.

after a few minutes the blond driver says " i know i must have one but i cant remember what it looks like."

the police woman says "its the square thing  with your picture on it dummy!"

a few more minutes of frantic fumbling and the blond driver feels a small square mirror in the bottom of her purse.  she pulls it out and looks at it, upon seeing her reflection she proudly hands it over to the blond
police woman.

the police woman looks at it and says " well, if you don't beat all !
what a waste of time! you should have just told me you were a police officer in the first place, you can go!"
