Happy National Cereal Day! We're celebrating the most popular breakfast food in America by paying tribute to a few of the greatest cereals of grocery stores past, from fabled French Toast Crunch to many that you may never even have heard of! Were you a fan of Urkel-Os? Or how about Mr. T's Cereal? These awesome (and weirdly branded) cereals might not be on the shelves anymore, but they'll stay fondly in our memories for years to come.
