Ok there's a blonde drivin down the road when she hears a siren behind her.
She pulls over and a blonde female copper walks up and asks for her license.
The blonde fumbles around in her bag for a few seconds and then asks the cop what it looks like.
The copper replies, its a small square thing with your picture on it.
The blonde fumbles around some more and pulls out a small mirror, looks into it and hands it to the cop.
The blonde cop looks at it and hands it back and appologises saying
"sorry ma'am, i wouldn't have pulled you over if i knew you were a cop too"
