Driving while knitting?

You’ve probably heard this one before, but here’s a joke for ya.

A woman sped past a police officer in her car.  The officer immediately went off in pursuit.  Driving up next to the woman’s car, he noticed she was knitting while driving!  And not paying attention to the flashing police lights behind her.  In an effort to get her to stop and, of course, give her a speeding ticket, he got out his bullhorn and said “Ma’am, pull over!” 

“No, it’s a scarf,” she replied.

(You may groan if you’d like.)
