A blonde, driving a bit too fast, gets pulled over by a female blonde cop.
The cop asks to see her license so she rummages thru her purse, opens her compact, and see'* herself. "Oh here it is!" she exclaims and hands it to the blonde officer.
The blonde cop opens it and closes it quickly and hands it right back
"Why didn't you tell me you were a cop!" she says and walks away.
