An old woman was speeding along a highway.
She passed a police officer who looked into her car and was shocked to see she was knitting.
He switched on his sirens and chased after the woman but after a while, he realised she was oblivious to his presence.
The officer drove up next to her and rolled down his window. With his bullhorn he yelled at the old woman, “Pull over!”
The old woman looked up in confusion and yelled back, “No! It’s a scarf!”
