Glee club
Glee club co-captain Rachel Berry (Lea Michele) attempts to take over for Will, but this results in chaos. At the request of Kurt Hummel (Chris Colfer), club lessons are instead covered by substitute teacher Holly Holliday (Gwyneth Paltrow), whose unconventional methods include discussing Lindsay Lohan's rehabilitation in Spanish, singing "Conjunction Junction" to her English class, and roleplaying as a bipolar Mary Todd Lincoln for the History class. When Holly first arrives at glee club rehearsal, she impresses the club with her rendition of Cee Lo Green's "Forget You". Rachel is annoyed and worries that Holly may be unable to sufficiently prepare them for the upcoming Sectionals competition. Holly later wins over Rachel by duetting with her on "Nowadays/Hot Honey Rag" from "Chicago".
