- Most of the opening intros.
- The streaker.
"Well, Ladies and Gentlemen, that was almost bound to happen."
- Better yet was David Niven's retort.
''Isn't it interesting that quite possibly the only laugh that man will ever get in his life...is by stripping down and showing off his shortcomings."
- Followed by Niven getting an ad-lib that brought down the house.
- Adrien Brody kissing Halle Berry after winning Best Actor for The Pianist might be one. But him doing an Anticipatory Breath Spray the following year is one for sure.
- Jack Black and Will Ferrell singing the "Get off the stage" vignette.
- Jack Palance doing one-armed pushups on stage after winning Best Supporting Actor for City Slickers. Also counts as a Crowning Moment of Awesome for the fact that he was 73 years old at the time.
- Billy Crystal has said he immediately thanked God upon seeing it, knowing he suddenly had a new fertile joke vein for the night. At various points in the telecast, Crystal announced Palance was backstage on the Stairmaster; bungee-jumped off the Hollywood sign; rendevouzed with the space shuttle in orbit; fathered all the children in a production number; named "Sexiest Man Alive"; and won the New York Primary. At the end of the show, Crystal told the audience he'd love to see them again "but I've just been informed Jack Palance will be hosting next year."
- Jim Carrey presenting Best Editing in 1999 while acknowledging his Award Snub for The Truman Show (they even show co-star Ed Harris, who was nominated).
- Jack Nicholson's acceptance speech after winning his first Best Actor Oscar: "And last, but not least, my agent, who about ten years ago advised me that I had no business being an actor. Thank you."
- Even better is his opening remark: "Well, I guess this proves there are as many nuts in the Academy as anywhere else."
- Patty McCormack presenting the 1957 Best Cartoon award.
- Roberto Benigni accepted his Oscars for Life Is Beautiful (for Best Foreign Language Film and Best Actor) as only he could: walking on the tops of the audience chairs to the stage and remarking that, "This is a terrible mistake, because I used up all my English!"
- The following year, when Roberto presented the Oscar for Best Actress in a Leading Role, Billy Crystal could not resist a great gag to followup: standing behind the star with a large butterfly net to restrain him if he gets so frisky again.
- The 1992 ceremony included a small, unplanned speech from a 100-year-old Hal Roach, but the man's words were unheard by the audience. Luckily, Billy Crystal made a joke on the spot saying that it was because Roach started out in silent films.
- When Tom Hanks won his second Best Actor award for Forrest Gump, he made a Call Back to the southern accent he uses in the film by saying, "So I went to the Oscars a-gain, and I got the award a-gain..."
- Robin Williams had many. Special mention goes to his performance of "Blame Canada" and announcing Best Animated Feature with a risqué routine compensating for another the executives forbid.
- During the 2007 show, Will Ferrell, Jack Black, and John C. Reilly singing the song "A Comedian at the Oscars", Lampshading comedy actors' and comedy movies' lack of recognition unless they turn to more dramatic works.
- George Lucas, Francis Ford Coppola, and Steven Spielberg presenting the Best Director award. An impressive trio, and all past nominees for that very category, causing Lucas (the only one of the three who as of this writing has never won) to remark that it's enough of an honor to be nominated, even if you don't win. Coppola and Spielberg both glare at Lucas, then turn to the audience and say, "No, it's not!"
- Both Best Actor and Actress speeches in 2009: long due for a win Kate Winslet mocks the award's nom leader ("Suck it, Meryl!") and Sean Penn opens with "You commie homo-lovin' sons of guns!".
- The 2010 ceremony had the "stars" of the five nominees for the Best Animated Feature award taking interviews. Even better, they're voiced by their original actors and animated in their movies' respective styles.
- The 2014 ceremony had an impromptu selfie moment with host Ellen DeGeneres and a number of stars. When the photo got put onto Twitter, it broke Twitter with how many reTweets it got. So many that it broke the record for most reTweets! note .
- Then, there's the order for "A Lot of Pizza". The delivery man thought that the pizza is for the writers of the ceremony until Ellen brings him to the stage with her and passes out slices to the audience.
- Also worth mentioning is Robert Lopez and Kristen Andersen-Lopez's acceptance speech when "Let It Go" won Best Original Song. Their acceptance speech was more like an acceptance song!
- 2015 host Neil Patrick Harris stripping down and walking from his dressing room to the stage in his underwear, spoofing a scene from Birdman.
- From the opening, his Take That to all of the acting nominees being white:
Neil Patrick Harris: Tonight we honor Hollywood's best and whitest— sorry, brightest.
- The entire performance of "Everything Is Awesome".
- Jared Leto calls the nominees for Best Supporting Actress as "four nominees and by virtue of California state law, Meryl Streep." Leto admits he was "nervous about that one" but Streep was shown laughing with everyone else on the Academy's tendency to nominate her practically every year.
- Best Picture in 2015: Sean Penn reacts to Birdman winning with "Who gave this son of a bitch his green card?" (referencing Mexican director Alejandro González Iñárritu - who directed Penn in 21 Grams, so it's just a friendly dig, albeit one some people reacted badly).
- In the previous year, John Travolta infamously mangled Idina Menzel's name ("Adele Dazeem"). Menzel had the chance to strike back calling Travolta to help her in Best Song ("Welcome my friend Glom Gazingo...").
- From the opening, his Take That to all of the acting nominees being white:
- The 2016 show actually managed one in its "In Memorium" segment, as the clip chosen to represent David Bowie isn't one of his highbrow films like The Man Who Fell to Earth, Labyrinth, or The Prestige, but his cameo from Zoolander. And it crosses into Heartwarming as Bowie never wanted to do anything predictable, and would have loved it.
- Again there is food involved, as host Chris Rock brings some girl scouts to sell cookies.
- Just like Neil Patrick Harris the year before, Chris Rock gets in a lot of digs.
Chris Rock: ...also known as "The White People's Choice Awards".
- The six awards won by Mad Max: Fury Road brought some colourful Australian people on stage. The costume designer attended with a leather jacket (complete with a bedazzled rendition of Immortan Joe's brand on the back) and scarf, earning some amused looks, and one of sound artists opens his speech with "Fucking Mad Maxers!"
- One montage inserts African-American comedians into some of the Best Picture nominees. Whoopi Goldberg becomes a janitor in Joy, lamenting that while "a skinny white lady" could get her own movie for inventing a mop, an African-American girl who cures cancer would probably only get a Made-for-TV Movie. Leslie Jones replaces a bear in The Revenant, attacking Leonardo DiCaprio as punishment for turning down her requests to appear in the film. Tracy Morgan portrays The Danish Girl, but pulls it off less smoothly than he believes. Finally, Chris Rock himself becomes an astronaut in The Martian, but gets left behind on Mars after Jeff Daniels and Kristen Wiig agree not to invest money into retrieving a black astronaut whom they even deny contacting them. Goldberg's janitor re-appears afterwards, and reminds Chris Rock that she warned him that none of the white personnel would save him.
