Ground hogs, made into hot dogs or pizza topping or a bacon explosion, become leftovers on the day after the Super Bowl. If you open the refrigerator and see the shadow cast by the leftovers blocking the refrigerator light, you will have six more weeks of salsa and chips.
The significance to the shadow on ground hog day is that, according to the Greeks, the shadow represents the sins of the soul and those are washed away by sleep, which is induced by continuous overindulgence in the beer and food prepared for the Superbowl. You may be doomed to wear your sins like a spare tire wrapped around your waist as a sign to all of the sin of gluttony. Or maybe that's just me.
I believe the Monday after the Super Bowl should be a leftover exchange day. Everyone should bring their leftovers to work and trade so at least you get some variety in your six weeks of follow up gorging.
