Every sensible person realizes that the only way to improve on the Egg McMuffin is to switch it up and order the Sausage McMuffin With Egg. Is it conceivable that in some remote corner of the universe McDonald’s is going to invent a better breakfast product? Yes, maybe. Or maybe not. Asking whether McDonald’s can make a better breakfast sandwich than the Sausage McMuffin With Egg is a bit like asking whether God could make an object so massive that he couldn’t move it.
