A blonde gets pulled over for speeding. The cop is also a blonde.
Cop: “Let me see your driver’s license.”
Driver: “What’s that?”
Cop: “A square thing with your picture on it.”
Blonde fumbles through her purse, finds a mirror, sees herself in it, and hands it to the cop.
Cop looks at it, hands it back and says, “I’m gonna let you go without a ticket. I didn’t know you were a cop.”
