KNITTING

A highway patrolman pulled alongside a speeding ca r on the freeway. Glancing at the ca r, 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!'
