History YMMV / TheGrimAdventuresOfBillyAndMandy

* TheyChangedItSoItSucks: A relatively minor example. The ending got changed from a creepy scene with ghosts floating down/up and the backwards message to TheTag. Fans wished that it was always the first ending.

* CharacterPerceptionEvolution: When Fred Fredburger first appeared, he was widely popular for his {{Cloudcuckoolander}} attitude and funny lines, and he was even briefly a BreakoutCharacter. After he started to appear in more episodes and Creator/CartoonNetwork promos, fans became more divided on him and were annoyed by his [[ToiletHumour poop jokes]], though many people still find him hilarious.

** Dracula and Judge Roy Spleen for being great examples of Creator/PhilLaMarr's range.

* SignatureScene: Billy's "cinematic masterpiece" rant in "Aren't You Chupacabra To See Me?" gained attention due to being subjected to MemeticMutation.

* SeasonalRot:
** The final season is considered the weakest season, though Underfist is well-regarded.

* SignatureScene:
** Pretty much the entirety of "Little Rock of Horrors", which is basically one long VillainSong.
** The "DESTROY US ALL" OverlyLongGag.
** Mandy smiling [[spoiler: and destroying the universe with it]] in "My Fair Mandy".
** Fred Fredburger's introduction in "Keeper of the Reaper".
** Many fans agree that the fight between Pud'n and the [[KillerRabbit evil bunny]] is one of the show's most [[SugarWiki/MomentOfAwesome awesome]] moments.
** Billy's "cinematic masterpiece" rant in "Aren't You Chupacabra To See Me?"
** Dracula's famous "scrape and lick" line.

* ToyShip: Admit it -- you've all considered Billy and Mandy to be a couple at least ''once''.

* DesignatedHero: Billy fell into this in later seasons thanks to {{Flanderization}}. Instead of being a KindheartedSimpleton, he comes across as a selfish, irresponsible brat who shows no remorse for the havoc he causes.

* ToyShip:
** Admit it -- you've all considered Billy and Mandy to be a couple at least ''once''.
** Or Irwin and Mandy.
** [[HoYay Or Billy and Irwin]].
** Or Junior and Mandy, to a lesser extent than the other two.
** Or Junior and Irwin. It's not as popular as some of the other pairings, but it's catching on.

%% * MoralEventHorizon: Mandy crossed this when... (use your own knowledge of Billy and Mandy!)

%% * MoralEventHorizon: (be free to add any example to it)

* DiagnosedByTheAudience: It's clear Billy has some mental health problems, including being incredibly stupid and going into psychotic, murderous rages. Not to mention he can barely focus and is often hyperactive. He likely inherited his parents' worst traits (his dad's complete idiocy and his mom's violent insanity).

** The episode where Billy meets mushroom-growing dwarfs has a scene where he escapes from Yogi and Boo Boo by hiding in a cave. Brown bears really are afraid of caves. Ironic as Yogi and Boo Boo live in a cave in [[WesternAnimation/YogiBear their source material]].

** THIS MOVIE ISN'T STUPID! '''''YOU'RE'' STUPID!''' [[labelnote:Explanation]]Billy's angry retort to Grim after the latter criticizes a videotape he is watching has been repeatedly quoted by fans to defend any movie with a polarizing critical reception.[[/labelnote]]

** "YOU FOOLS! ''YOU'VE MESSED WITH THE NATURAL ORDEEEEEEEEEER!''"[[labelnote:Explanation]]Sir Raven's reaction after Mandy smiles and causes reality to collapse. Said whenever a drastic change to the status quo of something happens, like [[spoiler:[[{{Anime/Pokemon}} Ash finally winning a Pokémon League.]]]][[/labelnote]]

** The second or third season after being split from ''WesternAnimation/EvilConCarne''; by then, its AdoredByTheNetwork status made it considerably less enjoyable. Though as BrokenBase above indicates, some see it as GrowingTheBeard.

*** The humor and tone are like ''WesternAnimation/InvaderZim'' taken UpToEleven, with plenty of gore, ToiletHumor, and the absurd brand of comedy popular in that era, and that's not to mention some of the one-off episode gags. Eris was a '90s ValleyGirl for her debut, for instance.

* NauseaFuel:
** Many of the injuries, such as when Pud'n [[EyeScream gets an eye full of cactus and pulls it off, revealing a hideous, skinless red eye]].
** "Wild Parts": The entire episode is nauseating, with multiple scenes where characters pick their noses or eat food contaminated with mucus, but the ending takes the cake. After the antagonist's nose explodes (covering the entire screen in snot in the process), Billy uses a knife to cut his own in half so he can share it with the Nose Wizard.
** "Hog Wild": There is a long, graphic scene where an alligator triggers his own gag reflex to vomit Billy. When the episode ends, the closing iris closes on Billy's head, causing a bunch of veins and snot to come out from his nose and his eye to pop out.
** "He Is Not Dead, He is My Mascot": The premise of the episode is that Billy forces Grim to resurrect the school mascot cat as an undead. That, in itself, is pretty bad, but when Billy asks the zombie to scratch his back, his skin and muscle get shredded by the splintered claws, causing his spinal column to poke out.
** "Zip Your Fly": Mandy accidentally swaps her head with that of a fly after messing with Grim's zipper. That's pretty standard for the show, but then after losing the zipper to the dump, she ends up eating ''the entire landfill'' before she can find it and get her body back.
** "Reap Walking": Harold eating a living, mucus-covered rat and slurping its tail as if it was spaghetti is probably the most disgusting scene on the show. Even the other characters, ''[[EveryoneHasStandards including Billy]]'', react to this moment with utter repulse.
** "The Loser from the Earth's Core": The close-up of Billy's frostbit hands, followed by one of his fingers falling off.
** "Herbicidal Maniac": Skarr disguises himself as a bush so he can stalk Billy. Unfortunately, Jeff mistakes the general for an actual plant and decides that's an ideal place to hide his offspring. What follows is a thirty-seconds long scene with Jeff graphically ejecting slimy purple eggs from his rear end into Skarr.
** "The Bubble With Billy": Billy swallows a magic gumball machine, which causes him to projectile vomit uncontrollably until most of the Earth is covered in sticky gum. After he is done, he suffers a sudden allergic reaction, causing his face to be covered in blisters and boils.

* HilariousInHindsight/TheGrimAdventuresOfBillyAndMandy

* HilariousInHindsight:
** In one episode, Grim is seen watching a ''Franchise/MyLittlePony'' [[MyLittlePhony parody]] called "My Troubled Pony" and enjoying it very much, in spite of the fact that he's a male adult and he's clearly not within the show's demographic. [[WesternAnimation/MyLittlePonyFriendshipIsMagic Fast forward to 2010...]]
** Nergal is a [[NoodlePeople tall and thin]] HumanoidAbomination with CombatTentacles and wearing a [[BadassInANiceSuit suit]]. Almost eight years after his debut, [[Franchise/TheSlenderManMythos a very similar character]] with no intentional connection to the show (per statements by the creator) would achieve widespread popularity online.
** In the beginning of ''Big Boogey Adventure'', Billy doodles "cops fighting dinosaurs" instead of writing out plans, and then remarks that "they should be working together" when Irwin calls him out. [[Webcomic/AxeCop It wouldn't be the last time that concept came up.]]
** ''Toys/MonsterHigh'' came out with a line of dolls called "Freaky Fusions", complete with an animated movie based on them. Obviously, the premise is based on [[HybridMonster Hybrid Monsters]]. It becomes funny when you realize that Maxwell Atoms already did this with the aforementioned Irwin. (Good thing they didn't do a mummy/vampire, otherwise he'd probably sue...)
*** In a reverse of this, the anime ''Anime/{{Kinnikuman}}'' featured a wrestler named Mr. Khamen, whose theme was simultaneously vampires ''and'' AncientEgypt (including a move that mummifies the opponent).
** Hoss Delgado has an eyepatch, a robot arm, a mullet and fights Grim who obviously has a skull for a face due to being a skeleton. Come 2015 where a [[VideoGame/MetalGearSolidVThePhantomPain a certain game]] features a protagonist with a robot arm, mullet and eyepatch fighting a character named Skull Face. Cue [[http://i.imgur.com/Ywq6R9n.jpg Hoss Delgado is Venom Snake]] [[http://i.imgur.com/aS2n9dT.png comparisons.]] Doubly hilarious since Grim himself is voiced by Greg Eagles, who had previously voiced [[VideoGame/MetalGearSolid The DARPA Chief and Gray Fox]].
** In the video game, Dracula and Irwin's victory quotes when beating each other become this (or maybe HarsherInHindsight, depending) when you realize Dracula is Irwin's grandfather.
--->'''Dracula''': Dracula need yo glasses! Dracula not seeing so good no more.
--->'''Irwin''': No! I'm allergic to vampires!
** In one episode, Billy wears Junior as a magic pair of pants to help pass a fitness test. (ItMakesSenseInContext.) As pants, you can still tell it's Junior because he still has his eyes (and glasses). Hm, people wearing magic clothes with eyes... [[Anime/KillLaKill Why does that sound familiar?]] (Tumblr's certainly caught onto this one.)
** This wouldn't be the last time Creator/NikaFutterman voiced [[VideoGame/KidIcarusUprising a depiction of]] [[Myth/GreekMythology Pandora]].
** In "My Fair Mandy", Mandy (sort of) sings "[[Film/TheWizardOfOz Somewhere Over the Rainbow]]" for the talent portion of the contest, complete with set and costume. Creator/GreyDelisle, who voiced Mandy, would later star as Dorothy and sing the same song (for real, not like the annoyed way Mandy was performing) in ''WesternAnimation/TomAndJerry and the Wizard of Oz''.
** [[https://www.youtube.com/watch?v=N9KGfgg-d8s Billy's irrational fear of clowns (along with "DESTROY US ALL!!!")]] is becoming this with reports of creepy clown sightings in real life (can combine with HarsherInHindsight as well).
** In the pilot episode, the toy monster Billy plays with has a head that's nigh-identical to that of [[Franchise/{{Pokemon}} Eelektross]].
** Grey Delisle would later go on to voice in [[WesternAnimation/{{TheLoudHouse}} another cartoon]] that features a black kid with glasses who has a crush on a blonde girl his best friend has relations to.
** In Hoss Delgado's introduction episode, Grim revives a bunch of dinosaur skeletons and makes them dance. [[Literature/TheDresdenFiles Harry Dresden]] does the same.
** The Brain-Eating Meteor from "Little Rock of Horrors" has a very similar appearance to Omni, the GreaterScopeVillain of ''Series/PowerRangersSPD''.
** In the Latin American Spanish dub, Mandy is voiced by Rebeca Gómez. [[Anime/DeathNote It wouldn't be the last time]] she'd voice a ruthless girl with blonde hair who's friends with a {{psychopomp}}.
** In "One Crazy Summoner", Dean Toadblatt is doused with a love potion and falls in love with the Squid Hat. This episode came out in 2005, and [[Literature/HarryPotter Professor Dumbledore]] (who Dean Toadblatt is a parody of) was [[WordOfGay revealed to be gay in 2007]].

* WhatAnIdiot: In the episode "Major Cheese" we meet the eccentric elderly bodybuilder Mighty Moe. Through blatant LoopholeAbuse of the way healthy lifestyle is graded, Mighty Moe has discovered a way to Immortality. As annoying as that is, it takes a turn for the worse when he plans to sell a book about said loophole. Obviously, this is Grim's problem and so he plans to shorten Mighty Moe's life.\\
'''You'd Expect''': Grim to psychologically or psychically hurt Mighty Moe lethally which would render the healthy lifestyle moot. If he can't do that directly for legal reasons hire an assassin.\\
'''Instead''': Grim's decides to feed him an unhealthy Cheese Puff.\\
'''Result''': Grim spends the majority of the episode in a HumiliationConga as Mighty Moe is either too savvy or insane to fall for any scheme involving eating the Cheese Puff.
