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 drivers seat reading a computer magazine and a young lady in the back seat calmly knitting. He stopped to investigate. He walked up to the drivers 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. Im 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 shes knitting a sweater Confused, the officer asked, How old are you, young man? Im 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 shell be eighteen.
