A cop was patrolling at night in a well-known spot for "parking."
He sees a couple in a car, with the interior light on. He gets
closer to the car & sees a young man behind the wheel, reading
a computer magazine& a young woman on the rear seat, knitting.

Puzzled by this surprising situation, the cop walks to the car &
knocks at the window. The young man lowers his window... "Yes,
officer?"

"What are you doing?" asked the officer. "Well, isn't it obvious? I'm reading a magazine..."

Pointing towards the young woman, the cop says: "And her, what
is she doing?"

The young man says:"I believe she's knitting a pullover..."

The cop is totally confused. A young couple alone in a car at night an nothing obscene is happening! "What's your age, young man?"

"I'm 25, sir..."..

"And her, what's her age?"

The young man looks at his watch & says: "She'll be 18 in 20
minutes..."
