Nickelodeon? Doubt it.

I seriously doubt this was ever intended for the Nickelodeon series. I've seen other sources (can't remember where) say that this was actually meant to be an episode of the Adult Party Cartoon, which aired on Spike and was completely unsuitable for children (and, frankly, adults as well). Given the information available, it's more likely to have been for the Spike series (which was cancelled after three episodes, meaning the remaining finished episodes went direct to DVD and several episodes were written and storyboarded, but not produced).

The article also says it was conceived after he was fired, so "Nickelodeon" should just be removed from the article title.
