A blonde police and a blonde in a convertible sports car

A blonde police officer pulls over a blonde in a convertible sports car for speeding. She walks over to the car and asks the blonde driver for some I.D. The blonde convertible 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 her picture.She hands the compact to the blonde cop.The blonde cop looks at the compact for a few seconds, then rolls her eyes, hands the compact back to the blonde convertible driver, and says, "If you had told me you were a police officer when I first pulled you over, we could have avoided this whole thing!"
