Stuffing should always be prepared out of the bird, for the reasons lifesaver mentioned.
I posted about Christmas dinner already, so I'll add what my family does for Thanksgiving. Dinner is always turkey, stuffing (bread stuffing cooked outside the bird), green beans (again, ick), mashed potatoes, jellied cranberry sauce. Dessert was ALWAYS ice cream cake, because my birthday falls on or near Thanksgiving. I've finally been able to convince my folks to serve pie, as I'd rather have the traditional pie than ice cream cake, but I still ask for a candle in my piece of pie.
Hehe - When I was about 12, my parents hosted Thanksgiving dinner for the family. My mother put the turkey in the oven in plenty of time. About an hour before it was due to come out, she checked on it, and it was still raw! Turns out the oven was set to "keep warm", which overrides the temperature setting and keeps the oven at 150 degrees. Dinner was late that year...
