Herman Dune and Jon Hamm

This gem has been out in the blogosphere for a while now, but it’s too great and strange not to share. Herman Dune is a French indie-pop duo that released their album, Strange Moosic, earlier this year. The music video for their single, “Tell Me Something I Don’t Know” got an extended video featuring Mad Men star Jon Hamm and a fuzzy animal that’s half muppet, half chewbacca.

While both the fuzzy guy—who apparently is a “young runaway yeti”—and Hamm’s character act harmless, the whole thing is just generally creepy. Ultimately, the thing doesn’t make a whole lot of sense, but the song is catchy and it’s an absolute must-see for Mad Men fans.
