Springfield can get crowded. And when Marge lets Lisa spend a summer at a hip performing arts camp, things hardly get less populated. Comedy duo Flight of the Conchords and a trio of Glee stars will all be guests in The Simpsons' season premiere.
In the episode, titled "Elementary School Musical," Jemaine Clement and Bret McKenzie will voice a pair of quarreling camp counselors, while the Glee kids will likely be friendly, theatrical bunkmates. But come on, Simpsons writers, just let Lisa go to her liberal arts college already.
