A cop is out on patrol, and sees a car parked in the local lover’s lane, with the windows all steamed up.
He knocks on the drivers window, and the guy inside rolls it down. The cop sees that there is a guy sitting in the front seat, fully clothed, and a girl in the back seat, also fully clothed.
“What are you up to here, son?”
“Well, officer, I’m reading a magazine, as you can see.”
“And what’s she doing back there?”
“I think she’s playing a game on her phone.”
“Have you been drinking tonight?”
“No, sir. I’m only twenty.”
“And how old is she?”
The guy looks at his watch and says, “Sir, in eleven minutes she’ll be eighteen.”
