A blond woman was speeding in her red sports car and was pulled over by a woman police officer who was also a blonde. The blonde cop asked to see the blonde driver's license.

She dug through her purse but was getting progressively exasperated.
"What does it look like?" she finally asked in frustration.

The policewoman replied, "It's square and it has your picture on it."

The driver finally found a square mirror, looked into it, and handed it to the policewoman.
The blonde officer looked at the mirror, then handed it back saying, "Okay, you can go. I didn't realize you were a cop."
