History HilariousInHindsight / SpongeBobSquarePants

* ''[=SpongeBob=] Freestyle Funnies 2018'' involved the entire Mermaid Man RoguesGallery coming together. Did United Plankton Pictures just predict VideoGame/SuperSmashBrosUltimate?

* The premise of "Krusty Dogs" involves the Krusty Krab getting a new menu item and changing its name. In Summer 2018, IHOP temporarily did the same, changing their name to "[=IHOb=]" to promote their new "Ultimate Steakburgers" (though unlike the Krusty Krab, they did not remove their signature menu item).

*** Or [[WesternAnimation/AdventureTime Lemongrab?]] Or [[WesternAnimation/GravityFalls Bill Cipher?]] Or [[WesternAnimation/StevenUniverse Yellow Diamond?]] [[OverlyLongGag Or]] [[WebOriginal/DontHugMeImScared Roy?]]

* A character with a lonely house life has a holographic "meal" prepared for him by his AI wife. Are we talking about Plankton and Karen, or [[Film/BladeRunner2049 Officer K and Joi?]].

* The premise of "Krusty Dogs" involves the Krusty Krab getting a new menu item and changing its name. Now, IHOP is changing its name to IHOB and selling burgers (thankfully not taking their pancakes off the menu).

* In "Can You Spare A Dime?", Squidward justifies quitting his job at the Krusty Krab by stating that he can be anything he wants, like "a football player, or a king, or a spaceman". Spongebob answers by combining all three suggestions into "a football-playing king in space", which would later come to be a pretty accurate description of one [[Series/KamenRiderFourze Shun Daimonji]].

* The episode "I'm with Stupid" has a twist ending: [[spoiler:Patrick's "parents" are not actually his parents. The M. Night Shyamalan movie {{Film/The Visit}} has a similar plot twist.]]

* This certainly would ''not'' be the last time Tom Kenny would voice a character [[WesternAnimation/FinalSpace that took care of a Gary who liked eating cookies]].

* This certainly would ''not'' be the last time Tom Kenny would voice a character that took care of [[WesternAnimation/FinalSpace a Gary who liked eating cookies]].

* ''WesternAnimation/FinalSpace'' fans would probably get a kick out of the ending of "Dumped"; why? because [[spoiler: THIS show's Gary was spending time with Patrick just to eat [[TrademarkFavoriteFood a cookie]] from his pocket]]. extra points for Tom Kenny voicing characters in both shows.

* In the episode "Krab Borg", one of the ways to tell if someone is a robot is to use love, because according to Spongebob, robots can't love. [[WesternAnimation/WallE 8 years later...]]

** And you can also add ''VideoGame/SuperMarioOdyssey'' to the list, given how you can A) mix and match costume parts, B) acquire [[spoiler:a football player costume in the Moon Kingdom ''and'' a king costume in Dark Side]], and C) [[spoiler:actually go to space]].

** Speaking of ''Kamen Rider'', in "Mermaid Man and Barnacle Boy V", an organization called "E.V.I.L" exists - which stands for "Every Villain Is Lemons". Did they predict [[Series/KamenRiderGaim Ryoma Sengoku/Kamen Rider Duke]]?

** Also in the episode, a fish can be seen kissing a pillow. This was before [[https://en.wikipedia.org/wiki/Dakimakura dakimakuras]] were a thing.

* In "Dunces and Dragons," Sandy's ancestor is known as "Film/TheDarkKnight"

* When SpongeBob was thinking up of ideas for a substitute friend in "Bubble Buddy," one of them was "Stick Buddy." [[Anime/AxisPowersHetalia Prior to Italy, Germany's only friend was a stick.]]

* In "Sandy's Rocket", when SpongeBob tries to convince Sandy that there are aliens on the moon, his "evidence" of aliens' existence consists of cowlicks, ninety-nine cent stores, and {{Atlantis}}. Four seasons later, in "Atlantis [=SquarePantis=]", he and Sandy, and a few others, would later visit Atlantis, and the people there [[spoiler: are an alien race that traveled to Earth to protect a bubble.]]
* SpongeBob's schedule in Party Pooper Pants sound like something [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle]] would use.

* The scene in "I Had an Accident" where a gorilla threateningly picks up SpongeBob seems to have gotten more popular after what happened with Harambe in the Cincinnati Zoo.

* In "Club [=SpongeBob=]", SpongeBob suggests Squidward consult the magic conch about what food to eat, to which Squidward mockingly replies "''Right after I consult the magic toenail''". Three seasons later, a toenail [[SuddenAnatomy magically appears on Squidward's foot]] [[AgonyOfTheFeet to be grotesquely peeled off]] by [=SpongeBob=] in "House Fancy".

* The episode "Best Day Ever" ended with [=SpongeBob=] and friends singing the song of the same name as part of a stage performance. Years later, the song would be featured in ''Theatre/TheSpongeBobMusical''.

* DeeBradleyBaker voices various fish characters and minor characters. One of his most famous roles would later be a [[WesternAnimation/AmericanDad talking fish.]]

* There was a short for Nickelodeon's "Ha Ha Holidays" block from the early 2000's called ''[[https://www.youtube.com/watch?v=jGPbeKdDBRE Patrick the Snowman]]'' that also served as a crossover between this show, ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' and ''WesternAnimation/TheWildThornberrys''; a few years later, ''WesternAnimation/TheLegendOfFrostyTheSnowman'' would not only feature voice actors who worked on one or more of these shows but Patrick's voice actor (Bill Fagerbakke) played the part of Frosty himself!

* Patrick's memetic "Is mayonnaise an instrument?" line in "Band Geeks" was just a way of showing how dumb Patrick is when the episode aired. Along comes Makey Makey in the mid 2010's. [[https://www.youtube.com/watch?v=RIqaic0pnpU Now mayonnaise]] [[https://www.youtube.com/watch?v=wkPt9MYqDW0 CAN be an instrument!]]
