I got this joke in an email forward this morning:)
A highway patrolman pulled alongside a speeding car on the freeway. Glancing at the car, he was astounded to see that the blonde 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!' the blonde yelled back, 'IT'S A SCARF!'
