A blonde police officer
A blonde female police officer pulls over a blonde gal in a convertible sports car for speeding. She walks up to the car and asks the blonde for her driver's license. The blonde driver searches through her purse in vain.
Finally she asks, "What does it look like?"
The blonde police officer tells her, "It's that thing with your picture on it."
The blonde driver searches for a few more seconds, pulls out her compact, opens it and sure enough sees herself. She hands the compact to the blonde cop.
After a few seconds looking at the compact, the blonde cop rolls her eyes, hands the compact back to the blonde driver and says, "If you would have told me you were a police officer when I first pulled you over we could have avoided this whole thing!"
