It all started with a rendition of “Bein’ Green” on an episode of Glee three weeks ago. And then two weeks ago, during the Harry Potter marathon on ABC Family, it was the spoof of the same station’s Pretty Little Liars.

And they’ve taken on pretty much every other blockbuster that’s come out in November, from Happy Feet to Breaking Dawn. Then last week they performed on Dancing With The Stars with a song and dance number from their movie, complete with commentary from Statler and Waldorf:

Waldorf: Whatcha Think?

Statler: I think if they get rid of all that singing and dancing it’ll be a hit!

Waldorf: The Muppet Movie?

Statler: No! This Show!

Just this morning, my husband saw an appearance of Gonzo on Mike & Mike . They’re campaigning to get 1 Bazillion Likes on Facebook , where you can find the Never Ending MAHNA-MAHNA. And they’re pretty much the only page (user or brand) that’s doing much of anything on Google+.

While most kids’ movies spend time and money targeting the children, The Muppets are also reaching Mom and Dad. Puss in Boots may be an exception, with its viral clips spoofing popular Dos Equis and Old Spice commercials, but The Muppets have completely immersed their brand in popular media adults consume, and manage to steal the show.

What an excellent example of how a brand can still break through the clutter and have an impact so integrated that it is impossible to miss. Awesome cross media integration and plenty of online content to engage kids from 1 to 92. I think this campaign has done justice to the Muppets that we all know and love and is sure to draw in the next generation to the imagination of Jim Henson.

Now excuse me while I go back to watching the Never Ending MAHNA-MAHNA.
