Specifically: Grover and Miss Piggy - backed by the rest of their Muppets and Sesame Street pals - sing Pharrell Williams and Miley Cyrus's 'Come Get It Bae'.
And it's an utter joy.
Thanks once again to Adam Schleichkorn, aka Mylo The Cat for another marvellous Muppets mash-up. If you haven't already, do check out his videos of The Muppets doing The Beastie Boys, Grover singing Daft Punk and Fozzie Bear performing Bob Marley. Trust us: they won't disappoint.
