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.
Some of these jokes which are censored for criticism of China are so tasteless that they ought to be censored in the American version as well, or better still, never written at all. A joke about whether the "chicken" at the local Chinese takeout restaurant is actually chicken? In the 21st century? That is supposed to be amusing?
