After watching a resident squirrel repeatedly try (and fail) to get at one of our bird feeders, I somehow got the image in my head of the squirrel sitting on Teddy's stool at Bob's Burgers chowing down. So I opened up CAD and decided to make my daydream a reality. That was almost a year ago, but I've finally gotten it published and wanted to share.
