A highway patrolman pulled alongside a speeding car on the freeway.
Glancing at the car, he was astounded to see that Sarah, 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 yelled,
"PULL OVER!"

"NO," Sarah yelled back, "IT'S A SCARF!"
