I would argue a lot of this 'article'. I mean ultimately it's all subjective, but when I think of Muppet movies, I wouldn't even put VMX, Oz, or Kermit's Swamp years in the same category. One reason is, obviosuly, they're tv movies or direc-to DVD release, but also because most of the other projects are so head and shoulders above them, there's no room for comparison. I also don't know if you can count a 'trailer' as a moment within the film?
But if you're talking about the best muppet moments, where's the finale to The Muppet Movie? Happiness Hotel? The rat sequence in MTM? Anything Jerry Nelson does in Christmas Carol? Cabin Fever?
As for worst, how about Kevin Bishop singing? Polly Lobster? and Muppets From Space isn't on that list nearly enough!! The author briefly mentions Hulk Hogan's cameo, but what about the Dawson's Creek appearance which took me so far out of the film, I wish I hadn't come back? I would almost agree to putting the MB sequence on the list not so much because it was a bad moment (it actually isn't. the song is catchy and the puppet design and look of it is neat. I also still can't figure out how Baby Rowlf does that head stand.) but I do think the series that followed became kind of a ugly stepsister the franchise which made the characters a little too 2-dimensional and nowhere near the quality of what we were used to.
Finally if we're going to allow cameos on these lists how about mentioning the brilliant and hilarious work of Mel Brooks? Steve Martin? Gregory Hines? Peter Falk? James Coco? John Cleese? Art Carney? Billy Connolly? and the always wonderful Jennifer Saunders?
