This video, of an actor performing Under Pressure while assisted by two Kermit the Frog puppets, has swept across the internet in the last several days. Some rumors had the performer being homeless, but he has since clarified that the video was done for "the men, women and children on our streets who don't have bright green puppets on their hands. The people who aren't always as easy to see."
Brilliant video, although to be honest, I'm surprised that Disney hasn't stopped this from being broadcast on YouTube given their near-fanatical protectiveness of their copyrighted images.
That being said, my second-favorite use of The Muppets is in Weezer's video for Keep Fishin'. Enjoy!
