First Aired: May. 19, 2009 on FOX
Summary: Will Schuester an optimistic high school teacher, tries to reinvent the McKinley High School's glee club, while reinventing himself. He challenges a group of outcasts to realize their true star potential, while facing harsh criticism from everyone in the school.
Sue Sylvester: [at cheerleading practice] You think this is hard? Try being waterboarded, *that's* hard!
Sue Sylvester: I have a phoner in a couple of minutes; that's an interview on the telephone, with a major media outlet. I'll probably do it on my iPhone.
Rachel Berry: I won my first dance competition when I was three months old.
- Goof (continuity error): When writing her name on the sign up sheet for the glee club, Tina adds extra Ts at the beginning to mimic the stutter that she often speaks with. When Rachel comes to write her name underneath Tina's the extra Ts are gone and Tina is written properly.
- Goof (factual errors): Sandy Ryerson says he got medical marijuana to treat his nervous breakdown. Ohio does not have medical marijuana yet. Michigan does, but bringing it across state lines would be a felony.
- Goof (revealing mistake): When we hear the narration by Rachel in the beginning of the episode, she states that she tries to post on MySpace everyday to keep her talent alive and growing. However, when the Cheerios are watching Rachel's cover of "On My Own", in the box that says "Similar Videos", it states that there are no other videos from Rachel.
- Goof (audio/visual unsynchronized): During "Don't Stop Believing," as Finn finishes playing the drums, he stands up and hands the drumsticks to the drummer, but we hear the drum fill continue while there is clearly no-one playing.
- Goof (errors made by characters, possibly deliberate errors by the filmmakers): When other students sign their names to the Glee Club sign-up sheet, we see Artie's name has been written as "Arty".
- Stephen Tobolowsky plays a character named Sandy Ryerson, the same last name as his character in Groundhog Day, Ned Ryerson.
- The scene where Rachel reprimands Finn for deciding to quit Glee because his friends tease him originally ended with her slapping him. In her audition, Lea Michele reached across the table without any hesitation and slapped one of the casting directors, who was reading Finn for her. When the other casting directors erupted with laughter, Michele sternly told them "This isn't comedy - that was my sad face! Now, I'm going to do it again and you're all going to cry."
- Dianna Agron (Quinn Fabray) was the last person of the original cast to get a part. On her first day she had to do a scene with Cory Monteith (Finn Hudson) in which they 'made-out' together. Director Ryan Murphy told her to look sexy, but she was so nervous that she couldn't focus.
- The band Kings of Leon was approached by Ryan Murphy about the use of some of their songs for Glee due to their uplifting message, but the band immediately told Murphy no and then insulted him and Glee online, leading to a lengthy public fight between the two parties where Ryan Murphy accused the band of homophobia and the band responded that they weren't and simply hated the show and would not be involved with it.
- Kurt sings the song "Cellophane" from Chicago. Chris Colfer sang the same song for his audition for the show.
