A policeman was patrolling near midnight at a local parking spot
overlooking a golf course. He drove by a car and saw a couple inside
with the dome light on. Inside there was a young man in the driver's
seat reading a computer magazine and a young lady in the back seat
calmly knitting.

He stopped to investigate.

He walked up to the driver's window and knocked. The young man looked
up, obligingly cranked the window down, and said, "Yes, Officer?"

"What are you doing?" the policeman asked.

"What does it look like?" answered the young man. "I'm reading
this magazine."

Pointing towards the young lady in the back seat, the officer then
asked, "And what is she doing?"

The young man looked over his shoulder and replied, "I think she's
knitting a sweater."

Confused, the officer asked, "How old are you, young man?"

"I'm nineteen," he replied.

"And how old is she?" asked the officer.

The young man looked at his watch and said, "Well, in about twelve
minutes she'll be eighteen."
