Dewey Decimal Sweater

Has anyone noticed that the DDC number for the subject knitting is duplicate-stitched onto a sweater at Knitty.com (here)? Wow. I love Dewey as much as the next librarian (especially for his intellectual snobbery, maliciousness toward other academics, constant womanizing, and hilarious spelling reform system), but even I'm not geeky enough to wear this (nevertheless AMAZING) sweater.
