Ditto Tales from the Crypt, except for me it was just The Cryptkeeper himself. I don't remember any of the specific stories; my cousin and I would watch them when we were 5-6 years old. We weren't old enough to even understand what was happening, but I definitely remember the skeleton announcer being really scary.

I didn't watch the show again until about 25 years later, and was surprised to find that the skeleton announcer was actually supposed to be funny. :D
