There's this blonde driving down the road at 100 miles an hour, and she’s knitting.
A policeman on a motorbike chases her for twenty miles before he manages to pull up next to her. "PULLOVER!" he screams at her.
"NO, SCARF!" the blonde screams back.
(What? Okay, so not the best use of blogspace, but I've been knitting a lot and I'm bored. And blonde.)
