omg, I hadn't thought about Rags to Riches in years! Yes, I definitely miss that show. Also Kids Incorporated, Alf (that was only on for about 2 or 3 years...how come it seems like so much more?), Growing Pains, Head of the Class, Who's the Boss?, You Can't Do That on Television, The Single Guy, Wonder Years, and Mr. Belvedere.
I would miss the Cosby Show, Fresh Prince, and Saved by the Bell if they weren't always on in reruns.
It would be cool if they showed the Saved by the Bell in Hawaii movie more often, though.
