* When Creator/TinaFey hosted in 2010, she did a sketch about Sarah Palin starting her own television network. In 2014, the real Palin did just that.
* In the snl town hall debate in 2016, one of the announcers calls Hillary Clinton "President Hillary Clinton". Come election day, Hillary's Opponent Trump wins by 58 delegates.

* In one "Weekend Update", [[Creator/NormMacDonald Norm [=MacDonald=]]] responded to a joke comment by Creator/JoelSchumacher that all the costumes in ''Film/BatmanAndRobin'' would have nipples by making a "note to self": "Do not see the new Batman movie!" [[InkStainAdaptation Good thinking on his part!]]

** Part of the humor taken from the "Miley Cyrus Show" sketches derived from teenage Miley maintaining her ContractualPurity on one hand, while awkwardly straining to break free from it and move on to a more mature image. Contributing to the humor were various hints that all in Miley's life were not as squeaky-clean as believed, and her "musical director" Billy Ray Cyrus' obliviousness to it all as it plays out in front of him. Now that the real Miley has changed her image entirely and distanced herself from her DisneyChannel/family-friendly days, the sketch would far less plausible as of 2016. It may explain why Bayer hasn't performed her Miley impression since the real Miley hosted in 2013, and even then, performed as "old Miley" time travelling to advise "new Miley" not to go ahead with her notorious performance at the VMAs that year.

* All the times Al Franken played a U.S. Senator, including a 1992 Clarence Thomas skit in which he was Sen. Paul Simon, became this now that he's a U.S. Senator for real.

* The ''Film/HighSchoolMusical 4: New Senior Class'' sketch from 2009 becomes this now that Creator/DisneyChannel is actually making a fourth film.

* One Saturday TV Funhouse sketch is about a fictional animated musical about the Titanic, featuring singing animals. The whole idea is just too stupid for someone to make one in real life, [[WesternAnimation/TitanicTheLegendGoesOn right?]] [[WesternAnimation/TheLegendOfTheTitanic RIGHT?]]
* During one sketch MileyCyrus played Music/JustinBieber saying that he would smoke Salvia (which Miley herself had done) because it's legal. In 2012, images of Bieber smoking the illegal marijuana surfaced and when Music/JustinBieber hosted ''SNL'', he appeared as a Bieber-hating member of Miley Cyrus' fan club who told Cyrus that he heard that Justin Bieber had smoked marijuana and was sorry for doing it.

* During the 25th anniversary special (broadcasted in 2000), a ''TV Funhouse'' short [[SelfDeprecation mocking Lorne Michaels]] showed him, among other things, advertising some SNL merchandise. One of the products he present is the ficticious 45th anniversary special [[{{VCR}} VHS]] [[TechnologyMarchesOn tape]], with a future appearance of Wayne and Garth, and Paul Simon as a musical guest, all of them very, very old-looking. Fast forward to 2015 and the real 40th anniversary, that included indeed a Wayne's World skit, and an aged Garth looks very similar to the animated depiction of the 25th anniversary (Wayne not so much); Paul Simon don't look as decrepit as in the cartoon, but the song he sings is the same: "Stil Crazy After All These Years".

* In 1998, Alec Baldwin hosted and during his opening speech Creator/JimmyFallon, then a new cast member, made an appearance and told Alec that he was given a prediction that he would become famous and host the show in 2011. Fast forward to 2011, where Jimmy is now one of TV's most popular television personalities and hosted SNL's Christmas episode. (Doubles as a FunnyAneurysmMoment: The sketch stated that REM was the musical guest for the episode Fallon hosted. REM broke up earlier that year.)

* On the BlakeShelton episode, the show spoofed The Deflategate scandal and revealed that the assistant equipment manager was behind it all. Just two days later, it was revealed that the NFL had begun investigating a locker room attendant.

* One of SethMeyers' celebrity impressions back before he was a Weekend Update anchor was Anderson Cooper. [[spoiler:On the Weekend Update for the season 38 finale, guess who Seth beats up at Stefon's wedding?]]

* A sketch on the Season 23 episode hosted by John Goodman (with musical guest Paula Cole) had a sketch where airline passengers are attacked by cobras. This sketch first aired in 1998, a scant eight years before the movie ''Film/SnakesOnAPlane'' hit the theaters.

* In 2010, Andy Samberg stars in a Digital Short called "[[https://www.youtube.com/watch?v=WRu_-9MBpd4 Great Day]]", a parody of "Zip-A-Dee-Doo-Dah" about a once-successful man whose spiralling addiction to cocaine has ruined his life, lost him his job and alienated his family. Jump forward to 2015, where Andy Samberg -- now cast as Detective Peralta in ''Series/BrooklynNineNine'' -- spends an episode being held hostage by a once-successful man whose spiralling addiction to cocaine has ruined his life, lost him his job and alienated his family. And to make it better, the addict in ''Brooklyn Nine-Nine'' is played by Chris Parnell, who also featured in the Digital Short "Lazy Sunday", which put Samberg on the map in the first place.

* Jimmy Fallon did this Weekend Update bit: "For those of you who don’t remember ''{{Series/Roots}}'', it follows a saga of Kunta Kinte from young African tribesman, to slavery, to [[Series/ReadingRainbow becoming literate]], and eventually being the [[Series/StarTrekTheNextGeneration top of his class at Star Fleet Academy]]." And the house band on Jimmy Fallon's talk show ended up being The Roots!

* On the BlakeShelton episode, the show spoofed The Deflategate scandal and revealed that the assistant equipment manager was behind it all. Just two days later, it was revealed that the NFL had begun investigating a locker room attendant.

* On the season 36 episode hosted by Scarlett Johanssen, there was a fake commercial for MTV's reality shows that focus on young mothers. One of them was called ''I'm Snooki and Pregnant'' (with Bobby Moynihan as Nicole "Snooki" Polizzi from ''Jersey Shore''). The fake commercial aired in November 2010. Snooki actually ''would'' be pregnant in March 2012. Whether this is HilariousInHindsight or a FunnyAneurysmMoment is up for debate.
