When Things Were Rotten

Over the weekend I watched the first episode of the Mel Brooks version of a Robin Hood TV series. I was surprised with how much of that first episode, alone, made it into the movie "Robin Hood: Men in Tights." There was a lot of jokes and bits that didn't really land to my modern sensibilities, but to my mid-40's self, there was a lot I still recognized in the satire and parody.

Any other early efforts in TV that are a worthwhile hunt based on how the subsequent treatments came out?
