Birthday Sex

A policeman passes a parking lot around midnight and notices a couple inside the parked car. He stops to investigate and sees a man in the drivers seat and a young lady sitting in the backseat, quietly reading a magazine. The officer knocks on the driver's window and asks what the hell is going on.

"Listening to music" the guy says. The officer then looks at the young lady in the backseat points at her and asks "What is she doing?" "Reading a magazine of course" says the boy sitting in the drivers seat. The officer definitely suspects something fishy is going on and asks to see the boys license and asks how old he is. "I'm 22 says the boy" with a big smile on his face

The officer then asks "And how old is she?"

The boy looks at his watch and then proudly back at the police officer and says "In 12 minutes she will be 18 years old"
