* DidIJustSayThatOutLoud: Principal [=McGee=]'s reaction after saying "If you can't be an athlete, be an athletic supporter." during her morning announcements.

%% * GettingCrapPastThe Radar: Due to overwhelming and persistent misuse, GCPTR is on-page examples only until 01 June 2021. If you are reading this in the future, please check the trope page to make sure your example fits the current definition.

* AdaptationalNationality: Sandy in the theatrical version was American, but when Olivia Newton-John was cast in the film version, the character was made Australian to account for her accent. In the 2016 version, she's changed to being from Salt Lake City, due to Julianne Hough being from Utah.

* AwardBaitSong: "Hopelessly Devoted To You". It was nominated for an Academy Award, but didn't win.

* DooWopProgression: Well, of course, the score is one great big homage to 1950s rock-and-roll, so, of course, this progression turns up in songs like "Mooning," "We Go Together," "Beauty School Dropout," and "It's Raining On Prom Night." And to top it all off, "Those Magic Changes" introduces it with a great big fat [[LampshadeHanging lampshade attached]] - the song's Broadway lyrics sing the doo wop chords that play through most 1950s songs:

* EveryoneHasStandards: Rizzo mocks a few people, especially Sandy (essentially the point of "Look At Me, I'm Sandra Dee"), but in "There Are Worse Things I Could Do," she sings that stealing and lying are beneath her.

* FiftiesHair: With the exception of Olivia Newton-John's anachronistic '70s feathered do during her bad girl makeover, the hairstyles are as '50s as it gets.

** After "Summer Nights," when Sandy mentions it was Danny Zuko she met at the beach, Rizzo remarks how her Prince Charming could show up again. She later arranges to surprise Sandy by reuniting her with Danny, as she knows full well that Danny is also attending Rydell.

* GainaxEnding: When all the Rydel students bid farewells with promises that they'll stay in touch, somehow Danny and Sandy's car lifts off the ground and flies off into the sky. It's so bizarre and out of touch for a 50's musical that many fans regard it as a BigLippedAlligatorMoment.

%% * IntercourseWithYou: ''You're The One That I Want.''

** Betty Rizzo is usually called "Rizzo" or "Riz." When she's making out with Kenickie in his car, she asks him to call her by her first name, but has to tell him what it is. Can also be considered a case of OnlyKnownByTheirNickname.

** The Teen Angel in "Beauty School Dropout," who encourages Frenchy to go back to Rydell, is clad entirely in white.

* AbridgedForChildren: The "School Version" of omits any swearing and references to cigarettes and alcohol. The song ''There Are Worse Things I Could Do'' is cut entirely.
* AdaptationDistillation: The [[http://www.ovrtur.com/show/119722/version/79875146 2011 ''Original Grease'' production]] combined drafts of the [[http://www.ovrtur.com/show/119722/version/79875476 Kingston Mines version]] with those from the [[http://www.ovrtur.com/show/119722/version/79875144 Broadway revisions]], expanding the total amount of songs from about 19 to 29 (While "Rydell Fight Song" and "Shakin' At The High School Hop" ''were'' included in the Broadway staging, they are unlisted due to being left off of the cast album).

** Due to Grease's popularity with younger crowds, a "kid-safe" version of the musical script exists for schools to perform. It's even more toned down than the modern versions used for Broadway, and is shortened to about an hour. Besides cutting songs down for language and timing purposes, Rizzo's pregnancy-scare is also eliminated.

* AdaptationalLocationChange: The musical took place in urban Chicago, while the film takes place in a more suburban locale. This was done by the director to reflecth his own teenage years in surburban Philadelphia.

** "You're The One That I Want" and the re-orchestration of "We Go Together" make up for the musical's somewhat lackluster ending (which originally just used a short reprise of the latter after "All Choked Up"). Both have been added to recent stagings.
** The film also adds a good solo song for Sandy in "Hopelessly Devoted To You". Before this, her big solo number was "It's Raining On Prom Night," which is only heard on a jukebox in the film. The 1994 revival had Sandy performing an adaptation of the pop hit "Since I Don't Have You", while the '71 off-Broadway version in Chicago had her singing a raunchy song called "Kiss It" to Danny (after her makeover).

* BookEnds: As Sandy is Australian in the film, when it opens on her and Danny at the beach, she's lamenting that because she has to go back to Australia, she might never see Danny again. Danny dismisses the possibility and reassures her that it's only the beginning, right before seguing into the AnimatedCreditsOpening. At the end, after "You're The One That I Want", the gang lament that once they graduate, they may never see each other again. Again they go on to dismiss it, and launch into the FriendshipSong "We Go Together".

* ElectricLove: Pops up in the FinalLoveDuet, "You're The One That I Want":

* RefrainFromAssuming: The song is called "Summer Nights," not "Summer Loving" or "Tell Me More."

* BittersweetEnding: In the 2011 staging of ''The Original Grease'', a middle-aged Patty Simcox reveals (in a TimeSkip epilogue) that some of the characters ([[spoiler: Danny, Sandy, Rizzo, Sonny, and Miller]]) have long been deceased.

* ProductDisplacement: Until TheNewTens, the diner boasted blurred out Coca-Cola signs. This is because Pepsi sponsored the film and objected to a competitor being shown prominently. The "Sing-Along" version has the sign replaced with the same texture as the wall and the 40th anniversary re-release in 2018 adds a historic Pepsi sign to it as well as digitally changing the Coca-Cola fountains to featureless orange fountains.

* ArtShift: The "Greased Lightning" number is filmed like a music video instead of a movie.

Creator/{{Fox}} televised a live adaptation of the musical on January 31, 2016, directed by Thomas Kail and starring Julianne Hough as Sandy and Aaron Tveit as Danny. Others included Music/CarlyRaeJepsen as Frenchy, Music/VanessaHudgens as Rizzo, and Music/KekePalmer as Marty. Mario Lopez appeared as Vince Fontaine, Wendell Pierce played Coach Calhoun (although Creator/MartinSheen was initially rumored for that role), and Music/BoyzIIMen were featured as the Teen Angels.

* FoodSlap: Rizzo throws a milkshake at Kenickie whenthey have an argument in a diner. She gets some on Frenchy to, for which she apologizes.

* AbridgedForChildren: The "School Version" of omits any swearing and references to cigarettes and alcohol. The songs ''Hopelessly Devoted To You'' and ''There Are Worse Things I Could Do'' are also cut.

* ThreeFacesOfEve: Sandy is the devoted Wife, Rizzo is the Seductress, Frenchy is the child.

* ADateWithRosiePalms: Rizzo suggests this when Danny leaves the T-Birds at her house after "Sandra Dee". [[InsultMisfire Danny doesn't really care]]:
-->'''Rizzo:''' Where you goin', to flog your log?\\
'''Danny:''' (''to her and the other T-Birds'') Much better than hangin' out with you dorks.

* ADateWithRosiePalms: Rizzo suggests this when Danny leaves the T-Birds at her house after "Sandra Dee".

%% * BreakTheHaughty: Rizzo gets this [[spoiler:with the pregnancy story line, as she is mocked by the other high school girls for it]]. She holds her head high, though.

* ItWillNeverCatchOn: In a clear nod to modern-day home media, Frenchy wishes that she and Doody could watch movies at home whenever they wanted. Doody replies to her, "We'll probably get to the Moon first."
