Does your family have any special traditions for Thanksgiving?

I am having my first Thanksgiving in my new home and would love to start some sort of tradition, other than just eating. I am looking for anything neat/special whether it be games, activities, trivia, etc. I have 2 kids (4 and 7) and the rest are going to be adults. Also, what are "must haves" at your Thanksgiving dinner? Any ideas are greatly appreciated.
