The Four Essential Food Groups of Thanksgiving

Yesterday, over a sumptious Thanksgiving dinner, I had an epiphany. I realized the four essential food groups of the Thanksgiving dinner: 1.) Turkey, 2.) Mashed Potatoes, 3.) Stuffing, 4.) Cranberry sauce. Now, some of the other guests at table objected, claiming that I had left out pumpkin pie. While pumpkin pie is by all means essential to the Thanksgiving holiday I think it only qualifies as an addendum to the first four food groups. Regardless, I ate all of the above and was most excellently satified with a good ol' American Thanksgiving. Thank God for those pilgrims!
