Okay, first of all the Michigan cake is a sandwich cake. Cut it open and it's just full of Reubens. It's all Bo Schembechler ate on birthdays. Good health for Schembechler started with a Reuben, and what celebration would be complete without the full spectrum of nutrition a Reuben provides? "It has all the food groups: salted meat, salad dressing, a fermented weed of some sort, a odorous bread, and cheese. It's THE TEAM of sandwiches because it smells when it gets hot, just like a great football team."
This is a real Bo Schembechler quote, don't bother to look it up.
