Polar fleece, because it's just so wonderfully warm and soft and fuzzy.

Doughnuts. I'm not talking about those icky shortening-laden store-bought ones covered with icing that's just pure sugar with a little water added, I mean little homemade deep fried ones with either powdered sugar on top, or real custard in the middle (not 'creme'). Having those only a couple of times a year is more enjoyable than store doughnuts every week, and probably better for you in the long run (despite all that grease and sugar.)
