* AcceptableTargets: There is an ancient mystical tome in the ghost realm called "The Book of Annoying Beings." The Ghostbusters are on one page. As the Ghostmaster rips it out in frustration, we see that the very next page is devoted to [[EveryoneHatesMimes mimes.]]
** Several pot-shots are taken at UsefulNotes/NewJersey. Understandable, considering the show takes place in New York.
* AnimationAgeGhetto: Interestingly, the show began life as an attempt to get ''out'' of this; given that Creator/JMichaelStraczynski ran the show early on, this shouldn't be surprising.
** The essential idea was to create a show that was acceptable for Saturday mornings, but would still get the same MultipleDemographicAppeal that the movie had, which is why you have unusually solid (and complex) writing and humor (with examples like "The Thing in Mrs. Faversham's Attic" or "The Hole in the Wall Gang"), episodes with near-psychedelic visuals like "Knock, Knock" and, uh, [[{{Fanservice}} a bit of occasional "focus" on Janine]]. Unfortunately, since TheMerch sold like crazy, the executives saw only dollar signs, and demanded {{Re Tool}}s to try and sell more merch. The writers revolted, many (including JMS) left and the show went right back into the ghetto. (Ironically this also drove away the wee kiddies to shows like, well, ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'' since the uniqueness of the early show is what drew people to it in the first place.)
* AuthorsSavingThrow: "Janine, You've Changed," considered by many fans the best use of this trope ever.
* BigLippedAlligatorMoment: At one point in "Banshee Bake A Cherry Pie", we get a scene of a lovestruck Venkman dreaming he's in a music video with a singer (actually a banshee) he has a crush on. Egon appears, interrupting the performance and then [[BreakingTheFourthWall breaks the fourth wall]] as the scene ends.
--> '''Egon''': "Uh hello, I'm Dr. Egon Spengler and you're not watching this overblown spectacle. It's totally in the banshee-riddled mind of my colleague here. Um, thank you."
* CompleteMonster: The Grundel is an evil spirit who enjoys corrupting children. He has minor CompellingVoice powers: if a child has history of bad actions and is getting into trouble all the time, the Grundel can often convince the child to invite him in. Once invited in, the Grundel will convince the child to commit more bad actions, such as convincing a child named Alec to tamper with the Ghostbusters' proton packs during a school assembly, endangering all the other children present. The more bad actions the child commits, the more the child falls under the Grundel's influence, eventually turning into a Grundel themselves and looking for more kids to corrupt. The Grundel also manages to convince Alec to bring his brother Lee to him so he can corrupt Lee as well, despite Alec's initial protests.
** The Grundel returns in ''WesternAnimation/ExtremeGhostbusters.''
* CreatorsPet - Arguably Slimer; he was TheScrappy to a lot of viewers, so what did the producers do? Rename the show ''Slimer and the Real Ghostbusters'' and have him show up even more. Then there were the Junior Ghostbusters. Yeah.
** Slimer was at least a little more bearable when he genuinely helped the Ghostbusters save the day, like when they went up against Killerwatt.
** A large part of the problem was that ExecutiveMeddling changed Slimer's character. Originally, Slimer was an affable sidekick that didn't speak coherently. While there were episodes where he would play a major role, there were others in which he barely appeared if at all. However, with the third season, Slimer started to take more focus in plots and began speaking coherently.
* FandomBerserkButton: This series and its concept is created by Creator/ColumbiaPictures (which produced the original movies), ''not'' DiC, who only did the animation work.
* FridgeHorror: The more feminine, mild mannered Janine with the long straight hair, rounder glasses and softer, less regional voice from the LighterAndSofter season 3 forward - with a few other makeovers along the way - becomes incredibly disturbing when you realize that she was secretly being manipulated and physically altered by a demon. By extension, pretty much all the LighterAndSofter episodes become a lot more disturbing when you realize what was happening with Janine and the demon.
* FunnyAneurysmMoment: The episode "Janine's Genie" has one scene in which the Ghostbusters, including Janine, tries to prevent a ghost-hijacked plane with the passengers inside from crashing in New York City. Janine and Peter, piloting the plane themselves, nearly avoided crashing against the WTC twin towers.
* HarsherInHindsight: The episode "Egon's Ghost" becomes heartbreaking in light of Creator/HaroldRamis' death.
* HeartwarmingInHindsight: Following 9/11, one of Peter's lines in "Knock Knock":
-->"Hey, this is New York. Nothing stops this town. I love this place."
* HilariousInHindsight: Peter gets possessed by a demon in an early episode. The symptoms? [[WesternAnimation/TheSimpsons Spiky hair and a yellow complexion]].
** The story goes that Lorenzo Music was dropped because Bill Murray was concerned about Peter Venkman sounding like [[GarfieldAndFriends Garfield]] and executives sought to accommodate him. If indeed true, well, that makes [[{{Film/Garfield}} a later Murray role]] very ironic.
** In "Revenge of the Ghostmaster", the titular spook taunts the Ghostbusters using his own personal television channel, GMTV - [[NamesTheSame no relation]] to the British breakfast-time show which started a few years later.
** Episode 105 involves the Queensborough Bridge being attacked by {{Troll}}s, which takes on a whole new meaning nowadays:
-->'''Peter:''' "It's Monday morning. Where else would trolls be but the Queensborough Bridge?"
** In "Janine The Ghostbuster", Peter jokes Janine should go into business for herself. In [[ComicBook/{{Ghostbusters}} the IDW comics]], she's now the leader of The New Ghostbusters.
* MemeticMolester: The Grundel. Just [[CompleteMonster the Grundel]].
* RetroactiveRecognition: Before hosting his own talk show, Arsenio Hall was voicing Winston Zeddemore.
* TheScrappy: The Junior Ghostbusters, a trio of kids that came with all the ExecutiveMeddling to make the show LighterAndSofter. None of the writers were thrilled with using them. JMS even once recalled saying he'd only use them if he could run them over with a truck. The kids only appeared twice here (though with [[AscendedExtra expanded roles]] on Slimer's own cartoony spin-off), but fans were still irritated because these two appearances took up screentime from the Ghostbusters' re-matches with fan favorites the Boogieman and Samhain, respectively.
** Slimer himself probably counts.
* SeasonalRot: "Makeoveris Lotsabucks" is a particularly bad example, especially since it could've been passed off as a kind of [[TheFairFolk proper fey]]. (Oddly enough, that example come from JMS himself, who [[TheyJustDidntCare may not have cared as much]] by that point - reportedly he made the name up as a TakeThat at the meddling executives who alienated him and most of the other writers in the first place.)
** Arguably the fifth season more than any other. After the syndicated episodes, Seasons 3 and 4 suffered from ExecutiveMeddling to be LighterAndSofter (as well as [[TheOtherDarrin replacement voice actors for Peter, Winston and Janine]]), but still had some fan-favorites. Season 5, however, awkwardly shoehorned in elements of the second movie. (Louis was one thing, Janine getting a second makeover to give her the hairstyle of her movie counterpart was another thing, but the city's injunction against the team was seen as forced.) Slapstick humor became even more apparent and a number of episodes saw a TwoShorts format instead of one story.
* SomeAnvilsNeedToBeDropped: The show was very rarely ''ever'' {{Anvilicious}} in any sense; "Janine, You've Changed", however, has a rather blunt anvil about not needing to worry about your appearance and weight and whatnot and trust that people will like you just the way you appear. And if you're at all familiar with [[http://en.wikipedia.org/wiki/History_of_anorexia_nervosa#In_Contemporary_Society the history of "youth beauty" and anorexia]] in the 80s and early 90s, that anvil ''seriously'' needed some dropping on the show's largest age group.
** "The Bogeyman is Back" boils down to there's nothing wrong with admitting being scared. Maybe it's laid on a bit thick, but considering the target audience, it's a very valid message.
* StrawmanHasAPoint: Anytime Peter complains about Slimer. In "Slimer, Come Home," he condemns Slimer for eating "anything that's not nailed down or on fire." In "They Call Me MISTER Slimer," he points out Slimer is responsible for a lot of bills that he doesn't have to pay for.
* TearJerker: The ending to "Drool, The Dog Faced Goblin".
* UglyCute (Slimer. The spud was actually pretty likable until he got [[WolverinePublicity overexposed]] in the later seasons.)
* TheWoobie: Slimer in some of his focus episodes, ''especially'' in "Slimer, Come Home."
