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 blonde cop asked to see the

blonde 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 in her purse, 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, 

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