How about this one... A blonde is speeding along in her red Corvette convertible when she hears sirens behind her. She pulls over and looks at the police officer approaching her car. The police officer is also a blonde. She asks the driver, "Ma'am, did you know you were speeding? Please hand over your drivers license." Blonde driver: What does it look like? Blonde cop: It's square, and it has your picture on it. The blonde driver rummages in her purse for a few minutes and then pulls out a mirror and hands it to the cop. Blonde driver: Is that it? Blonde cop, after looking at the mirror for a moment.... "You can go. I didn't realize you were a cop."
