History Trivia / TheGrimAdventuresOfBillyAndMandy

** The appearance of human Grim in "Night of the Living Grim" was originally meant to [[InkSuitActor resemble his voice actor, Greg Eagles]], before someone pointed out the [[UnfortunateImplications dubious optics]] of two white children basically owning a black man.

* CulturalTranslation: The show's Indian rights are with Cartoon Network India, which does not air the original English version of the series. They first aired the series under the name "Billy Mandy Aur Life Main Haddi", which wasn't successful. Then, in 2014 they re-aired the show under the name "Haddi Mera Buddy", which went on to become the second most viewed show on Cartoon Network India. They aired an Indian English version dubbed by Indian dubbing artists.
* DescendedCreator: Maxwell Atoms voices Jeff the Spider. He also voices Piff in the episode "Crushed".
* EitherOrTitle: Two episodes had alternate titles. "Breaking Things To Billy" would be seen as "Everything Breaks" and "Cubix Rube" became "The Show That Dare Not Speak Its Name."

** Atoms revealed on his Tumblr that he had [[https://maxwellatoms.tumblr.com/post/660003543871324160/if-krampus-had-been-more-well-known-when-you-were originally planned to use Krampus]] in the ChristmasSpecial, but since Krampus ''looks'' like a devil, he knew Cartoon Network would never allow it, so we got Vampire Stanta instead.

* RealLifeWritesThePlot: Part of the eeriness in "BRAINS" is how its performed in an odd off key. This happened purely on accident. Voltaire has even commented that he hasn't quite been able to match it since.

* UnintentionalPeriodPiece:
** There were four episodes entirely devoted to parodying the ''Franchise/HarryPotter'' movies, dating the show to at least the early 2000s.
** While most of the cartoon has aged gracefully, it was very much a product of the mid-2000s, and that is reflected in a number of things:
*** 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.
*** ''Wrath of the Spider Queen'' used the [[Film/SpiderManTrilogy Sam Raimi Spider-Man]] movie font as a selling point.
*** One episode has Grim dealing with a Windows 98 pastiche computer, complete with dial-up internet.

* JailedOneAfterAnother

* FanNickname: The show is often referred to as "Billy & Mandy" for short.

** ''Grim & Evil'' in its original format. While every individual episodes are easily available in the repackages of this show and ''WesternAnimation/EvilConCarne'' after both split up, it's very difficult to find ''Grim & Evil'' itself (possibly a result of this), and additional Mandy intros that weren't reused for the standalone ''Billy & Mandy'' series became rare. This is even moreso the case of the unaired third season, as it only properly aired as ''G&E'' in international countries. While the entirety of ''G&E'' was at one point made available through VOD services in 2017 (including the unaired third season, where it finally saw release), it was quietly removed in 2019.

* DescendedCreator: Maxwell Atoms voices Jeff the Spider.
** He also voices Piff in the episode "Crushed".

* NonSingingVoice: Inverted with the Meteor in "Little Rock Of Horrors," as most of his lines are just the original Music/{{Voltaire}} recording of "Brains!" The few times he speaks, he's voiced by Creator/JeffBennett.

** Creator/DavidWarner was the original voice of Nergal, but was later replaced with Martin Jarvis.

*** Rumor speculated that Eagles attempted a Swedish accent, but Eagles himself confirmed it was never the case.

* ThrowItIn: Greg Eagles originally intended to voice Grim with a Swedish accent as a ShoutOut to ''Film/TheSeventhSeal'', but it accidentally came out sounding more Jamaican and they decided to just go with that because it sounded funnier.

** He also voices Piff in the episode “Crushed”.

** Grim wasn't conceived as having a Jamaican accent. Greg Eagles just did a deep voice in his audition and was told to "put a twist on it." He attempted to do a Swedish accent, modelled after Bengt Ekerot's portrayal of Death in ''Film/TheSeventhSeal'', but it came out as Jamaican, which [[ThrowItIn everyone thought worked much better]].

* RelationshipVoiceActor: [[Creator/TomKenny The Secret]] [[Creator/BillyWest Snake Club's members]] are voiced by [[{{WesternAnimation/Futurama}} Philip and Yancy Fry.]]

** Creator/TomKenny reprises his role as [[WesternAnimation/YogiBear Boo-Boo]] in "Here Thar Be Dwarves" after previously voicing him on WesternAnimation/IAmWeasel and WesternAnimation/HarveyBirdmanAttorneyAtLaw.

*** The humor and tone are like ''WesternAnimation/InvaderZim'' taken UpToEleven, with plenty of gore, toilet humor, 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.

** Irwin's family is full of this. Irwin's dad, grandmother, and grandfather (Dracula) are all voiced by Creator/PhilLamarr. Creator/VanessaMarshall voices Irwin's mother and Irwin himself.

** "Brains!" originally had one lyric about {{Dumb B
londe}}s: "Bring me a brunette, a redhead, I just don't care, just don't bring me those girls with the long blonde hair, 'cause everyone knows there's nothing in there." Cartoon Network vetoed it for being potentially offensive.
