----
* ActorAllusion:
** When Victor Garber takes a break from his usually cool, hard-hitting persona to play Will's dad, he expresses his regret at never going to law school and at the end of the episode decides to apply. This is a ShoutOut to Victor Garber's portrayals of lawyers in many movies and TV shows (''Film/LegallyBlonde'', ''Series/EliStone'', etc...)
** Victor Garber is also known for his work in Broadway musicals (e.g., ''Theatre/{{Assassins}}''), thus his appearance in a show all about music and musicals is another {{lampshade|Hanging}} in an already overly-meta show.
** Rachel auditions for Glee by singing the song "On My Own" from ''Literature/LesMiserables'' (the musical). Creator/LeaMichele, the actress who plays Rachel, made her Broadway debut as Young Cosette in the Broadway cast of the same musical and more recently played Eponine in the Hollywood Bowl concert. For those not in the know, grown Eponine sings "On My Own". Young Cosette/Young Eponine (nonspeaking) rotate nights in most productions, so she would have played both roles.
** In the pilot episode, when Sandy sees Will at the linen store, his reaction is identical to that of [[Film/GroundhogDay Ned Ryerson]] every time he sees Phil in the street. Sandy's last name is Ryerson too (though WordOfGod says that the name "Sandy Ryerson" was scripted before the actor was cast).
** In the second episode, when Terri flicks the kitchen lighter with a very smug attitude (as opposed to her needy, slightly hysterical character) it could be an allusion to Jessalyn Gilsig's role in ''Heroes'' as Meredith Gordon, the smug and self-confident woman with the power to control fire and create a small flame from her hand.
** Terri's sister asks if her baby will be black, a reference to Jessalyn Gilsig's character (Gina Russo) in NipTuck.
** Rachel claims that nudity is one of the few things she won't do to break into the business, which is ironic considering Creator/LeaMichele's [[SpringAwakening other famous role]] involved some nudity on-stage 8 times a week.
** In Sectionals, Mercedes sings a song from Dreamgirls; Amber Riley auditioned for Dreamgirls.
** In episode 4, Kurt performs Beyoncé's "Single Ladies" in his basement along with Tina and Brittany (Played by Heather Morris). Heather Morris was one of Beyoncé's backup dancers in Single Ladies. Heather Morris actually started out in ''Glee'' as only being there to teach them that dance, and then later got the role as Brittany when it turned out they still needed a third cheerleader.
** [[Creator/NeilPatrickHarris Bryan Ryan's]] vocal exercises as he enters the theater sound [[WebVideo/DoctorHorriblesSingAlongBlog horribly]] familiar.
** In Episode 21, "Funk," it is revealed that Rachel is a vegan after the members of Vocal Adrenaline egg her in the parking lot. Lea Michele is a vegan in real life who has appeared in ads for PETA.
** In "Home" April sings part of "A House is not a Home". KristinChenoweth sings the song in the revival of ''Theatre/PromisesPromises''.
*** Also she wants to do a new version of TheWiz, which makes sense after being used to Oz already.
*** She also lampshades her "Cheno Notes."
** Kurt singing "Defying Gravity" is a reference to Chris Colfer's having been denied the opportunity to perform it earlier in life.
** Though unintentional, this isn't the first time Dianna Agron has played a [[Series/{{Heroes}} bitchy head cheerleader]].
** Will forbids the club from doing Britney Spears songs, in reference to how Matthew Morrison himself was opposed to doing a Britney Spears episode.
** Borders on AdamWesting, with Barry Bostwick and MeatLoaf playing conservative strawmen who want Sue to protest the Rocky Horror Picture Show.
** Magenta was played by an actress named Patricia Quinn in the RockyHorrorPictureShow. [[FridgeBrilliance Quinn]] Fabray [[InvertedTrope plays Magenta]] in the Rocky Horror Glee Show.
** In Never Been Kissed, Blaine, played by Darren Criss, the lead actor and songwriter for ''AVeryPotterMusical'', tells Karofsky that he's "Not Alone," the title of a recurring track from the musical.
** In "A Very Glee Christmas", Mike wishes for Channing Tatum to stop being in stuff. Tatum starred in the first Step Up. Harry Shum Jr., who plays Mike, had a role in Step Up 2 and Step Up 3D.
** In the "When I Get You Alone" number, Blaine tries on some [[http://www.google.com/images?hl=en&sugexp=ldymls&xhr=t&q=darren+criss+pink+sunglasses&cp=15&um=1&ie=UTF-8&source=og&sa=N&tab=wi&biw=1104&bih=623 pink sunglasses]] in a store.
** In ''Silly Love Songs'', Blaine tells Kurt about his plan to sing a song to someone on Valentine's Day, leading Kurt to believe that the song is for him, only to later find out it's for someone else. This isn't the [[AVeryPotterMusical first time]] a character played by Darren Criss has done [[http://www.youtube.com/watch?v=ldix5R8x7XI something like this.]]
** In "Comeback", Artie joins Sam's JustinBieber homage BoyBand, the Justin Bieber Experience, probably as an allusion to Creator/KevinMcHale's own BoyBand background. They even get to perform "Somebody to Love" in a particularly [=NLT=]-esque fashion.
** In the episode ''Sexy'', Holly Holliday makes a comment about not liking shows about doctors, in front of [[{{ER}}John Stamos's]] character.
** New Directions does a song from ''Film/{{Hairspray}}'' in "The Purple Piano Project". Matthew Morrison was the original Link Larkin on Broadway. If you notice, when he hears Rachel's opening notes, he smiles knowingly.
** "I Am Unicorn" is full of it:
*** Burt telling Kurt that, if he can't find any good roles for a kid like him, to "write them yourself". Creator/ChrisColfer just wrapped ''Struck By Lightning'', which he also wrote.
*** The choreography for "I'm the Greatest Star" has Kurt climbing all over scaffolding, hanging from it upside down, and spinning ninjitsu knives. All of which Chris is well known for liking and doing in real life.
** Blaine leads the club in a performance of [[KatyPerry "Last Friday Night"]], the music video of which he cameos in. With Artie, don't forget Artie.
** What about Kurt and Rachel's obsessions with Wicked? Don't they notice that April and Shelby look like Kristin Chenoweth and Idina Menzel?
** In "Lights Out" Sue sings "Little Girls" from ''Theatre/{{Annie}}''. Jane Lynch with be starring as Miss Hannigan on Broadway this summer.
** [[Creator/DemiLovato Dani]] becoming the character effectively replacing [[Creator/IdinaMenzel Shelby]], when Demi sang the single version of ''[[CrowningMusicOfAwesome Let It Go]]'', Idina's character's (heck, just 'the') most famous song from ''Disney/{{Frozen}}''.
** [[Theatre/SpringAwakening Wendla developing a crush on Melchior]], their actors being the same.
** In ''Series/HowIMetYourMother'', Creator/JaymaMays' character thinks it would be a good idea for a date to go to her dentist and have her teeth cleaned. Five years later, and Carl Howell appears on Glee.
* AdoredByTheNetwork: Being the biggest hit Fox has had since ''Series/AmericanIdol'', it was renewed for a third season only halfway through the first.
* AscendedFanon:
** The creators have admitted that the idea of Brittany/Santana as a serious, OfficialCouple started with the fans, that they never planned for them to be more than a one-off joke until they saw that the fans wanted more.
** Over at Website/TelevisionWithoutPity Brad is referred to exclusively as "Tinkles." April Rhodes later calls him this.
* AuthorExistenceFailure: Cory Monteith, who played Finn, died on July 13th, 2013.
** TheCharacterDiedWithHim: Ryan Murphy confirmed that Finn passed away as well, with Lea Michele's blessing, the character's cause of death was purposely never revealed.
* CastTheExpert: Heather Morris was only brought in to teach the Single Ladies dance (she was a back-up dancer for Beyonce on tour) but when the producers needed a third cheerleader, Heather Morris was cast to play Brittany.
* ChannelHop: Moved from Channel 4 to Sky (in the UK).
** Re-runs are still shown on E4, if you can't afford £40-odd a month for Sky (cable TV).
* ColbertBump: Has had this effect with some of the music they've featured on their show.
* ContractualPurity: There is a strange tendency in [[MoralGuardians some people]] to flip out every time Lea Michele or Dianna Agron appears on a magazine looking sexy. Yes, they are adult women in their mid-20s, not teenagers, yet somehow the fact that they play minors on TV means that they are "sending girls the wrong message" every time they so much as wear low-cut shirts. ''Glee'' is an unusual case, though, since it is not a kids' show and it engages in sexual and other adult themes ''on the show'', so this expectation is solely due to [[WhatDoYouMeanItsNotForKids viewer misconceptions]].
* TheDanza: Jacob Artist as Jacob (Jake) Puckerman and Brad Ellis as Brad the Pianist.
* DawsonCasting: All of the kids' actors are well in their 20's, with Cory Monteith (Finn), Mark Salling (puck), and Harry Shum, Jr. (Mike) being the oldest and only a couple years younger than their teacher. The closest exceptions are Chris Colfer (Kurt), Charice (Sunshine), and Damian [=McGinty=] (Rory), who were all in their late teens when their characters debuted.
** Inverted in the case of Matthew Morrison, who was 31 when the series premiered (born 1978). Will's Nationals performance happened in 1993, when he was (presumably) 18, which would have made him born in 1975, and the character three years older than the actor.
*** During the first season, there was a lot of kerfuffle regarding some—ahem!—pictures of the cast appearing in a gentlemen's mag. The reason: despite the cast pictured being above the age of majority and hence able to appear in the magazine in fairly provocative poses, they were portraying high school students in the series, resulting in some mixed messages occurring.
**** However, the show didn't really have a choice due to the fact the cast works very long hours that would violate Hollywood's child labor laws.
** Coming to the later seasons a lot of the new kids were quite young, which made Becca Tobin stand out even more around them. She's not that much younger than Matthew Morrison, also making her ''older than all of the Originals'' except Finn, Puck, and Mike.
* DirectedByCastMember: Matthew Morrison directed "Extraordinary Merry Christmas"
* EnforcedMethodActing:
** Brittany's famous nonsequitors were originally ad libbed. Other characters' confused reactions were real.
** Dianna Agron (Quinn) and Cory Monteith (Finn) were not allowed to see the other actors performing "Lean On Me" in "Ballad" before the scene was shot so their reaction would be real.
** In "Safety Dance," apart from the dancers, all of the extras were actual shoppers at the mall where it was shot.
** Jayma Mays (Emma) didn't know about Will and Emma's kiss in "Journey" until it happened. Matthew Morrison (Will) and Brad Falchuk had planned it secretly.
** In "Mash-Off" Cory Monteith didn't know Naya Rivera (Santana) was going to slap him, Director Eric Stoltz mouthed it to Naya in the very last scene. Made better by the fact that the slap was in fact real.
* ExecutiveMeddling:
** "Candles," the duet between Kurt and Blaine at Regionals, is considered by many to be the weakest Warbler song due to way in which Kurt and Blaine's registers clash. Normally the songs are overseen by music producer Adam Anders, but writer Ryan Murphy intervened for this song and specifically requested that it be sung in those registers.
** In the original draft for "Pilot," Rachel uses Website/YouTube to upload her songs (as a normal person in the year 2009 would do) but in the actual show version she uses Myspace. Why the change? The fact that the same company that owns Myspace also owns Fox, the company that produced Glee, probably has something to do with it.
*** In the flashback episode "2009", the show makes many jokes at Myspace's expense.
* FakeNationality: Both of Mike's parents make references to their parents in China, but Mike Sr. is played by a Korean and Julia is played by a Japanese-American. [[InterchangeableAsianCultures Go figure.]]
** Finn, Terri, Sugar and Hunter were all played by Canadians.
** Tina is Korean adopted into a Jewish family, but Jenna Ushkowitz is full-blooded Korean, adopted by an American family.
* FanCommunityNickname: Gleeks for the entire community.
** Many fans of Creator/ChrisColfer and Kurt call themselves "Kurtsies".
** People who are fans of both Glee and Creator/TeamStarkid are called "Stargleeks".
** There's a sizeable group of Mercedes/Amber Riley fans called the "Mercedes Mafia".
** Many of the ships have their own names. Klaine has Klainers, Niff has Nifflers, Brittana has "Gay Sharks" (after Brittany's meme-spawning quip), Kurtofsky has 'Pirates' (because fans have decided that it's a 'pirate' ship), Blainofsky has '[=BatKids=]' and Sory has Sponsors (after Sam was Rory's Christmas sponsor, and agreed to be his Valentine's Day sponsor as well).
** Obnoxious Klainers have earned themselves a nickname of their own, Klainer 12, where the twelve stands for the age, implying that they're immature.
* FandomNod:
** Finn's mom and Kurt's dad getting together.
** A lot of fans were disappointed that that the assigned Puck/Mercedes duet in Episode 10 never happened. So in Episode 18, they not only let them sing together but had them date as well.
** Shelby Corcoran as Rachel's biological mother. Nicely they kept us off the trail by making her the rival coach and head faking toward another LoveInterest.
** Subverted in that a lot of people wanted an OddFriendship to develop between Quinn and Rachel, especially for the homeless Quinn to move in with her. Such friendship and moving in did occur with Quinn - just with Mercedes.
** In Bad Reputation, Rachel told Puck that most of the school referred to them as "Puckleberry" while they were dating.
** Pretty much the entire opening sequence of the second season premiere is a nod to the biggest complaints of the show. [[TakeThat And it's awesome.]] The only problem with that? The show kept on doing that even when the complaints started being legitimate.
** Various characters in ''Duet'' calling Kurt out on his previous behavior in Season 1. It's like the writers read the JustBugsMe page.
** ''Furt'' gives us Finn mentioning "Puckleberry," "Finchel," and "Furt."
** "Silly Love Songs" gives a nod to a ''[[Creator/TeamStarKid different]]'' fandom during the Warblers' rendition of "When I Get You Alone". At one point, Blaine and two other singers grab sunglasses from the Gap's sunglass rack; the glasses that Blaine wears are Darren Criss's iconic pink sunglasses.
** "Rumours" has the club rattle off all of the fandom names for the official couples - and create two new ones. Pizes (Puck/Lauren) and Tina Cohen-Chang Chang (Tina/Mike). The actors themselves are in on it as Mark Salling gave Puck/Artie a name (Partie).
** "The Spanish Teacher" acknowledges a common fan complaint that on the rare occasion we hear Will speak Spanish, his accent is appalling considering he's teaching it in a high school.
* FanNickname:
** Finn is nicknamed "Frankenteen" due to his height, inability to cheer, and sometimes-stiff dancing.
** Many people refer to Tina and Mike as "Asian and Other Asian". It actually originated in-show, when Sue Sylvester called them that, and not long later even Tina, having drawn his name for a duet, said: 'The other Asian'.
** Klaine have sex is referred to as "Klex".
** People who don't like [[MarySue Blaine]] call him 'Bland' or 'Plain Blanderson'. And Klaine is renamed 'Kland'.
** Blaine is 'Hobbit' in many fanfic, especially the Kurtofsky ones.
** Fandom tends to call Kurt "Dolphin," due to Brittany's "dolphins are just gay sharks" line, or 'baby penguin' due to Blaine's comparing Kurt to one in season 2.
** Dave is referred to as 'Yogi Bear' or 'bear cub' from the Scandals scene in ''The First Time''.
** While not a nickname, there are quite a few people in the fandom who love Quinn's first name Lucy and call her by that in fanfiction.
** Joe is Teen Jesus
** The short dance Brittany and Santana share during The Troubletones performance of "Survivor/I Will Survive" has been dubbed the "Brittango".
* {{Fanon}}: An interesting case as it pertains to the Season 3-4 character Sugar. Ostensibly a copy of Rachel (minus the lack of vocal talent), it was called upon that actress Vanessa Lengies bore a resemblance to both Heather Morris and Naya Rivera. Couple that with a throwaway line made by Brittany about a time machine, and a section of the fanbase came to the conclusion that Sugar was in fact Brittany and Santana's daughter, coming from the future to insure her parents got together.
** Doubles as a form of AscendedFanon, as Lengies, Morris, and Rivera heard about this theory and ran with it, having scenes that act as nods to the fanon. Lengies left the show at the end of the fourth season, but made a cameo for the wedding episode, nodding up at the heavens in a way that suggests Sugar's mission was complete and thus her existence was guaranteed.
* FridayNightDeathSlot : Fox moved ''Glee'' to Fridays at 9pm for its sixth and final season.
* HeyItsThatGuy:
** The deaf choir director is the Operative's first on-screen victim in ''Film/{{Serenity}}''.
** "Wheels" has [[TheGuild Vork]] making a brief appearance.
** [[AVeryPotterMusical Harry Freakin' Potter]] is Kurt's new friend from Dalton Academy..
** [[SpringAwakening Wendla]] is the overpowering student "leader" of the Glee Club.
** The [[{{RENT}} bohemian performance artist]] and [[Theatre/{{Wicked}} misunderstood Wicked Witch of the West]] is the director of Vocal Adrenaline and Rachel's mom.
** The perky blonde [[Theatre/{{Wicked}} Good Witch]] is the [[TypeCasting perky blonde]] high school dropout and Will's short-lived romantic fling.
** Will divorced with [[Series/{{Heroes}} Meredith]] and now he's gonna be with [[Series/{{Heroes}} Charlie]].
*** Hiro should have suspected that Samuel would hide her in a small town in Ohio.
** Emma's new beau is [[FullHouse Uncle Jesse]].
** Rory, the Season 3 Irish Exchange Student, is played by the Boy Wonder from Celtic Thunder.
** Hmm. That [[NaughtyNun nun]] judge resembled [[Series/BostonPublic a certain high school music teacher...]]
** [[GoodLuckCharlie Ivy]] is one of Quinn's "skank" crowd in Season 3.
** [[StarWars Chewbacca]] in Artie's daydream was played by Peter Mayhew, the ''original'' Chewbacca.
** Hey, what is [[SpringAwakening Melchi Gabor]] doing in Ohio singing ACDC?
** [[Series/LawAndOrderCriminalIntent Zach Nichols]] is one of Rachel's dads.
** [[{{Frasier}} Cam Winston]] plays her other dad.
** Blaine's brother is [[WhiteCollar Neal Caffrey]]. Let's hope none of the New Directions are missing their wallets.
*** He's also [[Series/{{Chuck}} Bryce Larkin]]... Let's hope none of the New Directions wake up with all the US government's secrets in their heads.
** If you have a ''really'' good memory for faces, you probably recognize Sugar as Vange from the second generation [[AreYouAfraidOfTheDark Midnight Society.]]
*** Or just as Roxanne from ''Series/AmericanDreams''
** One of the new bullies in season 4 is [[NedsDeclassifiedSchoolSurvivalGuide Cookie]].
** Sam has the same dad as [[{{Smallville}} Superman]].
** If you pay attention during "Swan Song", you can see Ellis Wylie of ''Series/TheGleeProject'' - eliminated in her second week and back as a background extra that even Ryan wasn't aware of.
** ''SoYouThinkYouCanDance'' finalists have a habit of appearing on the show, mainly in competing show choirs (where the singing is actually done by a separate group of singers), although Courtney Galiano has been credited for having a speaking (non-dancing) part. At least one SYTYCD finalist has appeared on Glee before SYTYCD.
** Hey, remember that time Finn Hudson got eaten by a [[{{Series/Supernatural}} Wendigo?]]
** Kurt's dad is Mike O'Malley.
** Dave Karofsky's dad is [[Series/{{Lost}} Arzt]]!
** Kitty is [[RockOfAges Sherrie Christian]] [[note]] (Becca Tobin was the understudy for the role and only performed a few times)[[/note]]
** [[Series/PrettyLittleLiars Detective Wilden]] is a stripper that robbed the New York gang.
** [[Series/GossipGirl Nate Archibald]] is Quinn's new boyfriend.
** [[TheTroop Mr. Stockley]] is in David Martinez's class.
** Sebastian Smythe is also [[Series/TheFlash2014 the Fastest Man Alive]].
** One of the judges from "Sectionals" is [[PitchPerfect Aubrey Posen]]
** Quinn's dad is [[Series/GilmoreGirls Mitchum Hunzberger]], who's gotten himself a new StepfordSmiler blond wife and is an ass to another offspring.
** Skylar Austin goes from [[Film/PitchPerfect college acappella group the Trebletones]] back to high school with the group "Throat Explosion" in episode 11 of Season 5 -- not to mention also being on ''Theater/SpringAwakening'' in the original run.
* HilariousInHindsight: ''After'' the episode "Born This Way", in which the characters learn to accept and embrace their faults after Rachel says she wants her nose to look like Quinn's, Dianna Agron - ''who plays Quinn'' - got a nose job.
* Rachel and Quinn used to be real-life roommates.
** The list turns out to be even longer. Lea Michele has lived with Dianna Agron, Jonathon Groff, Naya Rivera, Heather Morris, Chris Colfer and Jenna Ushkowitz.
* KeepCirculatingTheTapes: Well, in the United Kingdom anyway, because people believe the DVD sets are EditedForSyndication versions.
* LyingCreator:
** After Idina Menzel was cast, Ryan Murphy insisted she would not turn out to be Rachel's mother. Pretty much no one bought it.
** Ryan Murphy also said that Finn and Rachel would stay together in Season 2. "Special Education" pretty much did away with that.
** When he accepted a GLAAD award on behalf of the show, RM promised the gay audience that Kurt would never be the victim. Cut to season 2, in which anti-gay bullying becomes a huge plotline. Of course, that was before the rash of well-publicized suicides due to bullying. Even those gay advocates who completely supported RM's initial standpoint agree that the way schools deal with homophobic bullying needed to be addressed, and that Glee did it perfectly.
*** YMMV on that "perfect" part.
** The entire "who is going to be Kurt's boyfriend" debate is a perfect example of this trope. From implying it'll be Sam to saying "Chord is definitely not the boyfriend" to "BLAINEBLAINEBLAINELOOKATBLAINEVERYONE" to "We haven't decided yet" (with the latter two included in the same interview, no less), well, somewhere in there there's several lies, though it remains to be seen which statements are lies and which are truth.
** As of Original Song, Kurt and Blaine are together.
** Although as of The Breakup, they are not.
*** They're married as of ''The Wedding''. This pleased the Klaine fanbase, ''and only them''.
* NamesTheSame: It's probably not the same [=McKinley=] as the one in the ''Film/FinalDestination'' series... though Creator/CoryMonteith did have a bit part in ''Final Destination 3''.
* TheOtherDarrin: The actors who end up playing Rachel's dads are different from the photos in Rachel's locker that we see back in "Pilot".
* PromotedFanboy:
** ''Series/TheGleeProject'' for Samuel Larsen, Damian [=McGinty=], Alex Newell, and Blake Jenner.
** DarrenCriss is also an example.
* RealitySubtext: A couple.
** Starting in the second season, Creator/ChrisColfer and Creator/LeaMichele's mutual adoration of each other[[note]]Lea has made no secret of the fact that she ''loves'' Chris, calling herself his number one fan; Chris is a bit quieter about it, but quite obviously returns her regard[[/note]] has spilled over into an in-show closeness between their characters. In fact, their "Happy Days Are Here Again/Get Happy" duet is quite obviously not just Kurt and Rachel enjoying singing together, but Chris and Lea ''loving'' singing with each other. And don't even get us ''started'' on "Ding Dong the Witch is Dead".
** Blaine sings the praises of Ohio State's football team. In real life, DarrenCriss graduated from the University of Michigan. The rivalry between OSU and Michigan is on the order of the Yankees/Red Sox feud.
* TheRedStapler: Has occurred with a good chunk of the music on this show. One of notable example is Music/{{Journey}}'s "Don't Stop Believin'." The effect on music is especially noticeable in the UK where the Glee music doesn't get radio plays but there is a significant increase in play time for the original versions of songs Glee has covered. When songs such as "Animal," which only just scraped into the top 40 on release, all of a sudden appear on a radio playlist the week the featuring episode airs in America, you KNOW this isn't a coincidence.
* RevivalByCommercialization: Most songs featured in the show are discovered by newer audiences - [[ColbertBump and even reenter the charts!]]
* RomanceOnTheSet: The cast must've gotten along really, really well because this happened not once, not twice, but maybe even three times.
** Cory Monteith and Lea Michele, who played Finn and Rachel, dated in real life.
** Melissa Benoist and Blake Jenner who played Ryder and Marley, are engaged in real life.
** Naya Rivera who played Santana, and Mark Salling who played Puck, dated briefly.
** and, Ali Stroker, a contestant and runner up on the Glee Project (a reality show that was essentially a casting pool for the 3rd and 4th seasons) eventually began dating another contestant!
* RuleThirtyFour: There is a '''HUGE''' section of fandom that revolves around not only LesYay but one of the girls (usually either Quinn or Rachel, but sometimes Santanna, or occasionally Brittany) secretly having a cock. Bonus points goes to the "were-peen" subgenre where [[NoPeriodsPeriod it only comes once a month in place of their period]]. No points for guessing how Quinn's pregnancy turns out in this universe.
* ScullyBox: Inverted. Chris Colfer had a growth spurt during the first season and is rather tall as a result, but camera tricks are frequently employed so that Kurt doesn't look taller than Blaine or Karofsky (notice how he rarely stands side-by-side with another guy).
* ShrugOfGod: The show is pointedly vague about how Finn died following Monteith's death, emphasizing that the focus should be on life, not death.
* StarMakingRole: For Lea Michele and Chris Colfer, the latter of which ended up winning a Golden Globe eighteen months after his professional acting debut.
* WhatDoYouMeanItsNotForKids: The way so many [[MoralGuardians "family values" groups]] reacted to the "Push It" number and the negative portrayal of the celibacy club in Episode 2 is a bit more understandable when you realize that a lot of parents of younger children were under the mistaken impression that ''Glee'' was ''High School Musical: The TV Series.'' (Which had nothing to do with the marketing of the show, but everything to do with the surface similarities - musical comedies set in high schools! - and [[PublicMediumIgnorance general public ignorance]] about musical theatre not always being a [[AnimationAgeGhetto "family friendly"]] medium.)
** If the Parents Television Council's uproar about the ''GQ'' cover and the more recent one lambasting Lea Michele's choice to appear in a low-cut photo on ''Cosmo'' are anything to go by, people are ''still not getting it.'' This was even unintentionally lampshaded by the people in the latter case, who said "Lea Michele may be an adult, but to pretend that she doesn't know her fans are 11 is just ignorance." Why should an actress on a show that has had subplots about teen pregnancy and when to lose your virginity, jokes about oral sex, a former teacher turning to drug dealing, and students taking uppers to do better in competitions be expected to cater to 11-year-olds?
** It doesn't help that Claire's, a store famous for cheap jewlery aimed at pre-teens, now sells a small ammount of ''Glee'' merchandise. Including make up sets for Rachel and Quinn, Team Finn and Team Puck necklaces, bracelets, and even knee socks.
* WhatCouldHaveBeen:
** Glee was at first conceived as a movie by Ian Brennan, he wrote the script in 2005 but it never got anywhere, in 2008 the script fell into Ryan Murphy's hands and he and Brad Falchuk (who worked with Ryan on Nip/Tuck) decided the concept would be better as a TV series.
** Originally the creators where going to include a character named Rajesh. However, Chris Colfer made such an impression at his audition (for Artie) that the character of Kurt was written specifically for him.
** The producers originally wanted a black girl in the Britanny role (who was then only ever intended to be a background character) but Heather Morris was given the part after teaching Chris and Jenna the Single Ladies dance.
** The ''Don't You Want Me'' duet between Blaine and Rachel shows what a lot of duets would have been like if Darren Criss was cast as Finn, the part he originally auditioned for.
** [[NextToNormal Aaron Tveit]] also auditioned for the part of Finn. Some of the more Broadway-obsessed portions of the fandom wish he had gotten the part.
** Creator/MaxAdler also auditioned for one of the male leads, and after [[http://www.youtube.com/watch?v=yHN_9Mfl4L8 hearing him sing]] [[HeReallyCanAct and seeing him act]] one wonders why he wasn't cast as one.
** Sam was originally intended to be the Kurt's romantic interest, but at the last minute the writers decided Chord's chemistry with Dianna Agron meant he would be better as Quinn's boyfriend. At the end of season 2 he and Mercedes had a RelationshipReveal that was supposed to continue on into the next season, but unfortunately Chord declined to come back after his option as a series regular wasn't picked up.
*** Then another WCHB instance cropped up after the writers introduced a highly likeable side character as Mercedes' love interest, shortly after which Chord ''did'' return and whatever plot line involving Mercedes and Shane were sidelined to bring Samcedes back into being.
** Telly Leung (Wes' actor) originally auditioned for Blaine.
** Samuel Larsen of ''Series/TheGleeProject'' (and eventual winner) auditioned for Sam.
** Naya Rivera (Santana) had originally auditioned for the part of Mercedes.
** Through no one knows what would have happened had Cory lived, Ryan Murphy had a plan:
--->'''Murphy''': The final year of the show, which will be next year, was designed around Rachel and Cory/Finn’s story. I always knew that, I always knew how it would end. I knew what the last shot was, he was in it. I knew what the last line was—she said it to him.
** Originally, "[[{{Theater/Rent}} Seasons of Love]]" was intended to be performed at some point during season 3 (possibly during the finale), as implied by an [[https://www.youtube.com/watch?v=HmZU3T6YllI unreleased cast recording]] of it that got leaked out to the internet, but was cut from the episode for unknown reasons.
* WrittenByCastMember: Chris Colfer wrote season 5's "Old Dog, New Tricks." Unusually for this trope, the producers actually approached ''him'' to write an episode (it may have helped that he had writing experience beforehand, having written the movie ''Struck By Lightning'' - which he also starred in, co-produced and novelized - and the book series ''The Land Of Stories'').
* So, the show loves Music/{{Journey}}. Naya Rivera originally auditioned for the part of Mercedes, but was given an unnamed cheerleader. What did they name this character, then? Santana. Like, Music/{{Santana}}? That being group which the founders of ''Journey'' (Neal Schon and Gregg Rolie) left and originally tried to recreate (with Journey) before Steve Perry arrived and they became more pop/ArenaRock than Latin-jazz.Yeah.
* ViralMarketing: Italian network "Italia Uno" ("Italy One") has aired bumpers such as [[http://www.youtube.com/watch?v=dJVN6QjETCU&feature=related this one]] (see the others in the related videos). [[IncrediblyLamePun GLEE-talia Uno!]] Evidently Mediaset wants to surprise [[ViewersAreMorons anyone who doesn't have internet and/or anyone who's never heard of Glee.]] It's almost sickening.
