To ellaborate on the circumstances that led to this episode being pulled by FOX due to violations of their standards and practises, the following reasons were supplied by Producer Lloyd Goldfine
"The final edited and mixed version of the notorious 'Insane in the Membrane' was deemed unsuitable for air by Fox Broadcast Standards and Practices. Apparently, in between the time the episode was written, storyboarded, animated and edited (all stages approved by Fox BS&P), and the time the show was mixed for air, there was a change of personnel in the Fox BS&P offices, and no one involved in the original approvals was still employed at Fox. Upon seeing the episode, they were said to be 'horrified' and that there was no way they could air the episode. I'm not sure I disagree with them - had there been BS&P comments earlier in the process, we certainly would have handled the show differently. But as it was approved at every stage, we went full steam ahead. In the end, I was told it was bad judgment on my part... so there you have it.
I believe this episode will eventually be available, but plans have not been finalized."
