Oh, yeah, I should have mentioned the Robin Hood aspect of it.
I did link to the Wiki page, though.
I remember a few bits, even though it's been close to forty years since I've seen an episode. When somebody proposes a toast, toast pops up out of the toaster. When the guards are told to put a peasant in his place, they pound him into the ground up to his neck with mallets. When it's mentioned that the walls have ears... yeah, you guessed it. And the cast is great. It's a pleasure just to watch them work.
