One night a cop was patrolling a well-known parking spot when he saw a couple in a car, with the interior light on. As he got closer to the car and saw a young man behind the wheel reading a computer magazine and a young woman on the rear seat, knitting. Puzzled by this surprising situation, the officer walked to the car and knocked on the window. The young man lowered his window and said, "Yes, officer?" "What are you doing?" "Well, isn't it obvious? I'm reading a PC magazine." Pointing toward the young woman, the cop asked, "And her, what is she doing?" The young man shrugged. "I believe she's knitting a pullover." The cop was totally confused. A young couple alone in a car at night, doing nothing but reading and knitting! "What's your age, young man?" "I'm 22 sir." And her, what's her age?" The young man looked at his watch and said, "She'll be 18 in 20 minutes."
