While everyone is lollygagging in the living room, and you have another ounce of energy, use kitchen shears to cut up the turkey carcass. In a soup pot, combine the carcass, any vegetables from the turkey roasting pan or the dinner, juices that accumulated on the turkey platter, even a few generous spoonfuls of pureed sweet potato or squash or stuffing. Add plenty of water, bring to a boil, cover, and simmer for 2 hours. Lift out the bones, letting any meat fall into the soup. Sprinkle bowls with chopped parsley.
