Just wondering if anyone can explain to me the difference between "the dungeon" sketches and "detention" sketches? I don't remember but I think that in the early episodes the kids got chained up in what was called "detention" in school but later it was called "the dungeon" which appeared to be located in a castle (in one episode they mention a "moat being flooded)-Were these interchangeable? Like were they supposed to be the same thing? did they use the same set? and did they always use the school principal character instead of Nasti in the Detention ones?Why did they change it from one thing to the other?
