A Blonde Police Stop

[retrocop]

A blonde was speeding in a 35 mile per hour zone when a local police officer pulled her over and walked up to the car. The officer also happened to be a blonde and she asked for the blonde's driver's license.
The driver searched frantically in her purse for a while and finally said to the blonde policewoman, "What does a driver's license look like?"
Irritated, the blonde cop said, "You dummy, it's got your picture on it!"
The blonde driver frantically searched her purse again and found a small, rectangular mirror down at the bottom. She held it up to her face and said, "Aha! This must be my driver's license" and handed it to the blonde policewoman.
The blonde cop looked in the mirror, handed it back to the driver and said, "You're free to go. And, if I had known you were a police officer too, we could have avoided all of this."
