Homemade Snuggie

I'm sitting at the computer, in a cold room, trying to keep warm. So I am trying my daughter's bathrobe on backwards. My front is nice and toasty. This works well, except my back is freezing. In the commercials you usually see the person lounging on a sofa, but I can't lug that thing in here. Guess I really need another robe/snuggie on my backside. Or I could just go back to bed!
