The Gruesomes:

C got me thinking about these guys. They were part of The Flintstones. I always liked monster familys (The Munsters, Addams Family, etc.). The Gruesomes were obviously based on Sonny & Cher, down to the wife's squeaky voice and large nose. For the longest time I thought they were "The Weirdly's", but it turns out Weirdly is the husband's name. I forget the other names.
