Blonde on Blonde

A blonde woman was speeding down the road in her little red sports car and was pulled over by a woman police officer, who was also a blonde.

The cop asked to see the blonde's driver's license. She dug through her purse and was getting progressively more agitated.

- What does it look like? - she finally asked.

The policewoman replied:

- It's square and it has your picture on it.

The driver finally found a square mirror, looked at it and handed it to the policewoman.

- Here it is - she said.

The blonde officer looked at the mirror, then handed it back saying:

- Okay, you can go. I didn't realize you were a cop.
