"Glee" Video: "Moves Like Schuester!" Artie and Matthew Morrison's Biceps Take on Maroon 5

It's been too long since the only adult on the show showed some skin

Glee's almost back on the air, and the previews are starting to roll out. Whether it's Sam (Chord Overstreet) taking a somewhat questionable path to a Letterman's jacket, or Artie (Kevin McHale) proving he's got the voice for just about any male pop song, Glee is ready to come back in a big way.

I never would have thought of mashing up "Moves Like Jagger" with "Jumpin Jack Flash" but Artie manages it seamlessly. And for whatever reasons, the number pairs the show's strongest male dancers, Mike (Harry Shum, Jr.) with Mr. Schuester (Matthew Morrison). I'm not entirely sure how the teacher being on stage makes sense unless it's related to the proposal, but this doesn't seem to be the most romantic song. Still, at least for part of the number, we get Morrison in a tank top, and that's always fun.

*hat tip to Perez for this

The performance seems to be for an audience of one, and that one is Becky (Lauren Potter), who seems to only have eyes for Artie, which could set up one of the shows most interesting romances.

This just leaves me one question, and it goes out to both Adam Levine and Glee: have you ever actually seen Mick Jagger's moves? Because I don't think you have.

Glee returns Tuesday, January 17th at 8 PM.
