Yesterday, I saw a review of "Muppets from Space", and the reviewer claimed that the reason Frank Oz isn't in "The Muppets" is because of the fart shoes joke. *facepalm*. First of all, Frank hasn't worked with the Muppets in like 10 years. The fact that he isn't in "The Muppets" really shouldn't be shocking. Also, when did Frank ever mention the fart shoes joke?
