These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Even the show's detractors say Charity Bazaar is the best character.
Flat Character: Most of the cast, really. As opposed to Tiny Toons or Animaniacs, the leads on this show usually had only one side, one joke, one reaction to anything, though, for this show, it was more about making fun of history than developing characterization.
Nightmare Fuel: Josef Stalin's song about what he loves can definitely be seen as this.
They Just Didn't Care: About historical accuracy, due to Rule of Funny and the fact that some historical facts had to be toned down for the show's audience (it's kinda like what happened with Time Squad, though Time Squad often got away with some historical facts that most educational kids' shows wouldn't touch).
