How about...
Cook up some hamburgers and hot dogs, get a fondue going if you can and make some s'mores. Spread a picnic blanket in the midst of your living room, take out your paper plates, plastic forks, serve the hamburgers and hot dogs on a bun, then crank up the radio with some oldies songs - maybe the Beach Boys if you have it.
Voila - let the snow come and wind howl, you're warm in your own picnic oasis.
