Stars Come Out for Simpsons 22nd Season

The Simpsons will soon embark on the show's 22nd season. While no one ever seems to age in Springfield (except maybe Grandpa Simpson), you have to wonder how many episodes the creators have left in them. Maybe Hollywood is wondering that as well, because the upcoming season will be star-studded, to say the least.

Fox just announced a few of the episodes we can expect, and have attached many famous names.

An episode titled "Elementary School Musical" will feature Jemaine Clement and Bret McKenzie of Flight of the Conchords as artsy camp counselors to Lisa, as well as Lea Michele, Cory Monteith and Amber Riley from Fox's own Glee.

The 21st annual "Treehouse of Horror XXI" will include the voices of House star Hugh Laurie, as well as Harry Potter himself, Daniel Radcliffe.

Facebook creator Mark Zuckerberg, baseball legend Mike Scioscia, and sports writer Bill James will all appear in "MoneyBart." Mad Men star Jon Hamm will play an an FBI supervisor in "Donnie Fatso." Martha Stewart will pop up in "The Fight Before Christmas," which also includes live-action puppets.

Other voices you can expect to hear include Kristen Wiig, Paul Rudd, Rachel Weisz, Alyson Hannigan, Danica Patrick, Cheech & Chong, and Kareem Abdul-Jabbar.

The 22nd season of The Simpsons premieres Sunday, September 26 on Fox.
