You've probably already seen it, or at least you think you have. Much of the Muppets' version of Queen's "Bohemian Rhapsody" video is as good as the Henson-era Muppet Show. So you might even have moments where you feel like you're "remembering" seeing it, when, in fact, it's entirely a Disney-era New Muppets creation, part of their virmup [viral! + muppet!] relaunch of the brand.
But Miss Piggy absolutely ruins it at the end, and then Kermit somehow ruins it even further. I guess it's somehow fitting, but inevitably sad that, without Henson, Kermit has become an annoying, cynical poseur who wields his petty puppet power without a hint of awareness of the hand shoved up his ass. If Disney had any guts, they'd just hire Steve Carrell to turn Kermit into Michael Scott and be done with it.
