The Glee kids have really made it. First, they win a Golden Globe award, then they get their own national tour, and now? A role on The Simpsons! Glee characters Rachel (Lea Michele), Finn (Cory Monteith), and Mercedes (Amber Riley) will be featured on the season premiere of The Simpsons, airing Sunday, Sept. 26, and first look images have been released. (But where are the slushie stains?) In “Elementary School Musical,” Lisa Simpson heads to performing arts camp, where she runs into miniature versions of these New Directions members, as well as Flight of the Conchords‘ Jemaine Clement and Bret McKenzie as camp counselors.
