* AlternativeCharacterInterpretation: Stimpy. Really, he is as stupid as often implies? Or is it just a false stupidity as a reason to be funny? Since it may be argued that it's incredibly smart to be a MadScientist.
* SugarWiki/AwesomeMusic: The opening theme song, "Dog Pound Hop", [[DoItYourselfThemeTune written and composed by Jim Smith and John K himself.]]
** The eclectic selection of stock sound cues have some very memorable tracks of music, particularly cues like Beethoven's "Pastoral Symphony" and "Clair De Lune", among other obscure pieces of classical music.
** [[http://www.dailymotion.pl/video/x79zxf_ren-stimpy-the-royal-canadian-kilte_shortfilms The Royal Anthem of the Canadian Kilted Yaksmen]]
** No wonder, since this is the melody of "God Save The Queen".
** In the German dub it's absolutely ''beautiful''. Especially when Ren harmonizes with Stimpy.
* BizarroEpisode: The series is very offbeat to begin with, but even then some episodes stick out like a sore thumb, such as "Haunted House" (which was an unmade Tiny Toons episode that Spumco was supposed to have a hand in, but ended up making for themselves).
* CreatorsPet: George Liquor. Many people (both in-universe and in real life) dislike him, but Creator/JohnKricfalusi, somehow, is really fond of him (possibly due to him being the only Ren and Stimpy character he still owns).
** Fortunately, we'll never see him again--but ''un''fortunately it's because [[AuthorExistenceFailure his voice actor died in mid-2010.]]
** A more nuanced example, since the character actually only appeared in a couple of episodes of the series, largely due to Nickelodeon's hatred of the character and thus having no problem handing Kricfalusi the rights to him when he left the series. He has a potential future however, with Kricfalusi himself as TheOtherDarrin.
* EarWorm: Many of the stock sound cues, including classics like "Pizzacato Playtime", "Screw on the Loose" and "Folli the Foal".
** The Muddy Mudskipper TV show theme.
** The LOG song.
** The "Loop of Death" music from Adult Party Cartoon, which is a recording of the classic jazz song "Hold That Tiger".
* EnsembleDarkhorse: Mr. [[AccidentalPun Horse]] since the character is based on Creator/KirkDouglas and Powdered Toast Man for being a hilarious LargeHam. It also helps that the latter is voiced by [[WesternAnimation/RogerRamjet Gary]] [[WesternAnimation/SpaceGhost Owens]]
* EsotericHappyEnding: Ren and Stimpy's tearful reunion in "The Big Shot" is cut short by [[{{Tsundere}} Ren]] slapping Stimpy for giving away his 47 million dollar fortune.
** In "Rubber Nipple Salesmen", Ren and Stimpy succeed in selling their rubber nipples to a suburbanite couple... who then kick Ren and Stimpy onto the backs of a couple of crazed bulls that they ride into the distance.
** "Powdered Toast Man" ends with PDM becoming president after saving the Pope; in office, he promptly ''burns the Constitution to start a fireplace'' (which was edited on American TV after it first aired) as he spends time with his lovely assistant.
*** "Man's Best Friend". By [[FamilyUnfriendlyViolence thrashing George Liquor half to death]] with an oar, Ren earns his approval and praise for being such a good guard dog. Ren and Stimpy are then rewarded with doggie treats, and the three of them dance happily to an upbeat RaymondScott song. (The aforementioned thrashing was one of the things that pissed off Nickelodeon and led to them firing John later.)
* FanonDiscontinuity: The Games Animation episodes and the Adult Party Cartoon episodes might as well have not existed in the eyes of fans.
* HarsherInHindsight / FunnyAneurysmMoment: While it's less funny and more genuinely emotional, "The Littlest Giant", where Stimpy (playing [[ExactlyWhatItSaysOnTheTin The Littlest Giant]]) runs away from home after a long time of torture by [[{{Jerkass}} the mean]], [[CatsareMean larger giants]]. Made harsher by the fact that nowadays, [[ButtMonkey bullying]] [[TheChewToy victims]] have often done pretty much the same, [[DrivenToSuicide or worse]] (just ask the corpse of [[http://en.wikipedia.org/wiki/Suicide_of_Phoebe_Prince Phoebe Prince]] or the many kids who come to school with weapons to get back at their tormentors and end up on the news for causing yet another school shooting).
** The romantic tension between Powdered Toast Man (whose secret identity is that of a clergyman) and his Catholic schoolgirl assistant. After the Catholic clergy sex abuse scandals of the 2000s, this comes off as ''really'' unsettling (though the only good thing you can take from this is, "At least the lovely assistant wasn't a boy. ''Then'' it would have been unwatchably awkward.")
* FreudWasRight: All over the series in regards to Ren And Stimpy's relationship. And as mentioned above, the implied romantic tension between PTM and his assistant in "Powdered Toast Man", especially the ending shot where they start a fire and [[GettingCrapPastTheRadar roast a weenie and marshmallow over it.]]
* GeniusBonus / TruthInTelevision: In "Fire Dogs", Stimpy puts out the building fire with kitty litter; in real life, Kitty Litter ''is'' usually inflammable, since it's often made out of ground up clay.
* GrowingTheBeard: The show definitely got off to a good start, but the second season is universally considered a significant improvement over season 1's helter-skelter quality, and by many to be the series peak; Ren and Stimpy's personalities and voice work are more fleshed out, the drawings, animation quality and background art are much better (especially the episodes animated by Carbunkle) and the cartoons became much better in story structure, humor and pacing. Even the heavily contested Adult Party continued raising the bar higher; it had some of the [[AnimationBump most ambitious animation ever made in a western made-for-tv cartoon]]-- the drawings and animation blow anything from the original series out of the water, the background art shirted from heavy stylization to a more naturalistic look and more in line with the painters personal styles , and the tone, characterization and acting (especially in episodes like "Ren Seeks Help") go further than even the standard set by the season 2 episodes.
* HilariousInHindsight: In "The Big Shot!", one of Stimpy's lines in the Muddy Mudskipper cartoon, "I'm huntin' for a wabbit!" and "Blow me down!" Years later, Creator/BillyWest (Stimpy's voice actor) was hired to play Elmer Fudd on ''TheLooneyTunesShow'', and also briefly played the role of {{Popeye}} in the 2004 made-for tv special.
** In [[http://www.dailymotion.com/video/x7vj5v_gross-ren-and-stimpy-moment_fun this clip from "The Altruists]], Ren is using a [[ThirtyHs groinsaw]].
** Anthony's dad from one episode bears a striking resemblance to a certain [[VideoGame/MetalGearRisingRevengeance memetic senator from the Metal Gear franchise]]. Demonstrated [[http://www.youtube.com/watch?v=My75o38w8Ys here.]]
** Many have noted that Powdered Toast Man's lovely assistant bears an uncanny likeness to Elizabeth from BioshockInfinite.
* JerkassWoobie: Ren in 'Stimpy's Fan Club'.
* MemeticMutation: The LOG song, from a recurring [[ParodyCommercial fake-ad bumper]] in the series.
** "HAPPY HAPPY, JOY JOY!" [[note]] Stimpy's recurring catchphrase, as well as the famous song number from "Stimpy's Invention". [[/note]]
** Ren's infamous catchphrase "You eediot!"
** The "Ren Snaps" sequence from "Stimpy's Fan Club", where Ren imagines himself as President, pressing "The Button" which atomizes Australia, has become a popular meme on Website/YouTube called "You Dare Not Agree With X", where a picture of X character is photoshopped over Ren.
-->'''Ren''': WHAT DO YOU MEAN YOU DON'T AGREE WITH ME?! [[YouDontKnowWhoYoureDealingWith DO YOU KNOW WHO YOU'RE DEALING WITH?!]]
** "You're the pitcher, I'm the catcher!" [[note]] An obvious gay innuendo phrase, said by Stimpy [[ItMakesSenseInContext while he is playing baseball with Ren under the bed]], from the Adult Party Cartoon episode "Onward And Upwards". [[/note]]
** "Don't Whiz on the Electric Fence!" [[note]] A meme spawned from "Sven Hoek", which is the name of the eponymous, [[NoOSHACompliance peculiarly unsafe board game]], which has a catchy jingle associated with it. [[/note]]
** The [[http://www.youtube.com/watch?v=ZPUj1mf3eiU Loop of Death]] from Adult Party Cartoon seems to be gaining this status.
** "You SICK LITTLE MONKEY!" [[note]] Ren hurling an insult at Stimpy for putting the Happy Helmet on him in "Stimpy's Invention", which morphed into an unofficial Catchphrase for Ren, [[BeamMeUpScotty even though he barely ever says the line in the series.]] [[/note]]
** "No sir, I don't like it!" [[note]] Mr. Horse's CatchPhrase, which sometimes appears in variations, such as "No sir, I am a real horse!" or "No sir, I didn't like it!" [[/note]]
** The History Eraser button segment from the end of "Space Madness", especially for the over the top delivery of the "Jolly, CANDY like button!" line from the announcer.
** [[http://www.youtube.com/watch?v=My75o38w8Ys Surprisingly]], Anthony's Dad, due to his visual similarities to a [[VideoGame/MetalGearRisingRevengeance certain crazy US Senator with superhuman abilities. NANOMACHINES, SON]]!
* NauseaFuel: One of the reasons why MoralGuardians and MediaWatchdog groups hated the show almost as much as they did old-school ''Simpsons''.
* SeasonalRot: The Games episodes. The Adult Party Cartoon episodes tried to turn things around, but, alas, those episodes made the Games ones look like the Spumco ones.
* SeinfeldIsUnfunny: The show was Nickelodeon's first big breadwinner and hugely popular in its prime, and many of the shows elements, particularly it's humor and drawing style, were shocking and unprecedented when it first hit the air. As a result, it ended up becoming one of the most [[FollowTheLeader ripped off]] cartoons of all time, to TV cartoons what [[Disney/SnowWhiteAndTheSevenDwarfs Snow White]] is to animated features and what VideoGame/MarioKart is to racing games. Nearly everything the show pioneered that was considered unique and groundbreaking when it first appeared have since been so heavily imitated that they're now considered ubiquitous elements of contemporary cartoons--[[CreatorBacklash much to John K's chagrin]], since he felt that those cartoons only copied the many, many mistakes he made on the show, instead of what he felt he did right. Though, unlike most cases of SeinfeldIsUnfunny, this show is still as raunchy and disgusting as it was back in the 1990s (even more so, now that the fans who watched this as kids have grown up), so much so that it has a 12 rating in the UK (and the song "The Lord Loves a Hanging" song was cut, because the BBFC objected to portraying hanging oneself as a fun activity and not a painful, excruciating death) and Common Sense Media's website put this series as "Unsuitable for Anyone Under 15."
* SignatureScene: The "Happy Happy Joy Joy" sequence from "Stimpy's Invention" is by far the most iconic scene in the series.
* SongAssociation: Due to it using so many stock music cues, some of these pieces of music have become strongly associated with the series.
* TheyWastedAPerfectlyGoodCharacter: Dr. Brainchild from "Blazing Entrails" only appeared once.
* UglyCute: Both of them!
* UncannyValley: That female anthro chihuahua with a realistic head (whom Ren falls for) in "Marooned".
* WeirdAlEffect: The LOG song is very well remembered from the show, but very few people realize that besides being a parody/homage of old toy commercials, the titular song borrows its melody directly from [[https://www.youtube.com/watch?v=X41Tq3svxNY vintage Slinky commercials.]]
** The "Loop of Death" music from an episode of Adult Party Cartoon is actually an old jazz number called "Hold That Tiger", and the recording used is from an old BettyBoop cartoon.
* WhatDoYouMeanItWasntMadeOnDrugs: Or better yet, [[YouHaveNoIdeaWhoYoureDealingWith What Do You Mean You Don't Agree With Me?]]
* WhatDoYouMeanItsForKids: Just look up an episode. Any episode. You '''will''' be surprised when you find out that it was rated Y-7 during its airtime, while containing suicidal jokes, the use of the word crap and loosely censored "hell", racist jokes, tons of GettingCrapPastTheRadar, Ren's disturbingly realistic [[AxCrazy mental breakdowns]], [[HoYay homosexual undertones]] between the main characters, BodyHorror, loads of BlackComedy and disturbing images, among many other things. Though, this could be sort of justified, since it aired in the early 90's, the era when it wasn't completely uncommon to have heavy themes in kid shows.
* TheWoobie: Stimpy, at times. Especially true in "Son of Stimpy" and "The Littlest Giant".
** Ren counts at times too, though usually he's more of a JerkassWoobie.
** ''Both'' of them, in the episode 'Man's Best Friend'. Poor guys don't catch a break until the very end!
