If you have seen “Pirates of the Caribbean: At World’s End,” you probably saw this unusual trailer for “The Muppets,” the movie that marks the return of Kermit the Frog and co. to the big screen.

It begins with what appears to be a preview for a rom-com starring Amy Adams and Jason Segel. But that’s just the fake movie within the bigger movie that features Miss Piggy, Animal, Fozzie Bear and the usual fuzzy, felt suspects. Watch below, then feel free to hum “Rainbow Connection” quietly and repeatedly to yourself until the film comes out this Thanksgiving.
