10. Urkel Os
How can you not want this cereal? Family Matters was a great show on its own, but Steve Urkel made people tune in week after week to see what he’d be getting into next, and if he’d ever win Laura Winslow over. Urkel O’s was clearly a prop to promote the show, but it was still cool to see on the shelves when Urkel-mania was at its height. Honestly, we’d buy a box right now, even if just for nostalgic purposes. If only it came with a pair of geek glasses.
