'The Middle': Chord Overstreet's back at school

While he was a mere high school student when we last saw him on screen as "Glee's" Sam Evans, Chord Overstreet returns to prime-time Wednesday (Sept. 28) evening on "The Middle" as an elementary school teacher. Talk about range.

Overstreet guest stars as Mr. Wilkerson, Brick's (Atticus Shaffer) teacher -- a teacher whose new age-y teaching philosophy (there's an "answer ball" involved) doesn't fly with Brick's dad, Mike (Neil Flynn).  

Oh, and if you're having trouble recognizing old Trouty Mouth, he's rocking his natural sandy-brown hair color.
