"Caught Speeding." joke

A highway patrolman pulled alongside a speeding car on the freeway. Glancing at the car, he was astounded to see that the lady behind the wheel was knitting! Realizing that she was oblivious to his flashing lights and siren, the trooper cranked down his window, turned on his bullhorn and yells, "PULLOVER!""NO," she yelled back over the sound of the siren, "It's a SCARF!"
