If you are lucky enough to live near a Waffle House, or will be traveling on Christmas you already know that the Waffle House is open 24/7/365.
That means that they are open on Christmas, so after you open those presents under the tree, send someone out to your neighborhood WH and carry out breakfast. Waffles, eggs, grits, omelets, and scattered, smothered, covered, and chunked. This will get your digestive system warmed up for the the big Christmas Dinner to come later that day. The Waffle House basically "shocks" your system and anything else you eat that day will taste great. Not sure about that warm fruitcake Grandma brought, but what the heck. Put another waffle on for me...
