After failing to come up with any new ideas for Simpsons episodes, the writers decided to call it quits and throw in the towel... then, as they gazed upon the towel they threw, suddenly became struck with inspiration and wrote a whole episode around it. At least, that's how I imagine this rag episode came about.
I didn't see it, but I read the Wikisimpsons article about it, which is chock full of insane plot details like "Moe is part yeti," "Moe has a magical talking bar rag from the Middle Ages voiced by Jeremy Irons," "Milhouse's mom chokes on a rock and refuses the Heimlich maneuver," and "Moe is part yeti."
Judging from the feedback on the internet, "the rag episode" represents yet another low point for the series, like jockey gnomes, "the Israel episode," and whatever that Ke$ha thing was.



A TV Squad critic is infumed that some people think The Simpsons decreased in quality over the past decade or so, and that some of those people are using the internet to voice that opinion.
