I yearn to tell you the yarn about the truck driver who was knitting a sweater using multi-colored yarn while he was driving.
Here's the story: To pass the time while he was driving, a long distance truck driver was speeding along the highway knitting a sweater. He apparently was controlling the steering wheel with his knees and not really paying attention to his driving.
A police officer who observed such driving behavior, drove along the side shouting on his speaker, "Pull over! Pull over!"
The truck driver leaned out the window and yelled, "No officer, it's not a pull over, it's a cardigan."
