Haha, funny this should pop up today. My coworker finally got someone to knit him a Dr. Who scarf (he asked one of our knitter coworkers a couple years ago but then got sticker shock at the amount of yarn needed.) Unfortunately very few of our coworkers know who/what Dr. Who is--I heard him explaining to a number of people what he was supposed to be, and at one point heard him sadly say, "It's been on since the 1960s..."
