A blonde female police officer stops a blonde female for speeding and says, "You were going pretty fast. I am going to have to ask to see your license."
The blonde motorist digs through her purse and then looks up at the officer, and says, "Can you tell me what it looks like?"
The officer replies, "It's rectangular and has your picture on it."
The blonde motorist digs through her purse some more and finds a small rectangular makeup mirror, looks at it and then hands it to the officer.
The officer looks at the mirror for a moment and says, "You can go. I didn't know you were a cop. "
