From what I remember, this show used to come on at 7pm on Saturdays. I would only watch it at every other weekend, so it most likely came on Saturday nights. It was hosted by a skeleton who was either a puppet or possibly even CGI. The show included puzzles and a segment involving pipes and a talking wrench.
It's not "Tales From the Cryptkeeper" or "Funnybones." If someone could please tell me the name of this show, I'd be very grateful! It's been bugging me for a long time now.
