It's really interesting that such a bland, un-subversive show whose only mentions of sensitive topics are in bad throwaway jokes is so heavily censored. I guess a more interesting show would just not get aired at all.
Actually, I wonder if that would be a "good" way of making a comedy that can be shown everywhere. Just film like 40 minutes per episode for a 30 minute slot, but only include throwaway jokes to they can be removed as needed.
I read somewhere that if you're writing humor for kids, you have to strip out a lot of the context: they might not know what an Eiffel Tower is, but they will understand Big Thing. Maybe comedy that can be shown everywhere is comedy a child can understand?
