* ActorAllusion:
** Koosie making a pepé wrap is also an allusion to Creator/DomDeLuise's second career as a cook.
** Rasslor from the ''Dial M For Monkey'' episode of the same name was voiced by RandySavage. His last line in the episode was, naturally, "''OH '''YEAAAH!'''''".
** "Just An Old Fashioned Lab Song" is wall-to-wall references to guess star Music/PaulWilliams' music and personal life. [[note]]This includes: his height, his appearance, his songs ("We've Only Just Begun"), his album titles {"Here Comes Inspiration") his album covers (the title card is made to look like the cover of his album "Classics"), and even ''his car!'' Thankfully, they didn't include the substance abuse.[[/note]]
* AdamWesting: Koosalagoopagoop is voiced by Creator/DomDeLuise and is a parody of the increasingly saccharine Creator/DonBluth movies [=DeLuise=] had been in, like ''WesternAnimation/ATrollInCentralPark''.
* AdoredByTheNetwork: Well not surprising considering it was one of Cartoon Network's first successful original animated series. But from 98-2001, it, along with ''WesternAnimation/PowerpuffGirls'' were the flagship shows of the network.
* CrossDressingVoices: Dexter was voiced by two women in English. In Mexican Spanish, German, Danish and Portuguese dubs Dexter is voiced by a man.

* HeyItsThatVoice: Dexter's first voice was [[WesternAnimation/{{Rugrats}} Chuckie Finster]], Film/{{Babe}}, and [[WesternAnimation/DarkwingDuck Gosalyn Mallard]] (Creator/ChristineCavanaugh); his second voice was [[WesternAnimation/TinyToonAdventures Sweetie Bird]], [[WesternAnimation/FostersHomeForImaginaryFriends Coco]], [[WesternAnimation/SwatKats Ann Gora]], [[Film/CoolWorld Lonette]], and that loud, obnoxious teacher (and the mom) from ''WesternAnimation/CowAndChicken'' (Creator/CandiMilo).
** The ending narration over the credits was provided by {{Creator/Mako}} (Aku from ''SamuraiJack'')
** Dexter's Mom is voiced by Creator/KathSoucie who voices a lot of other characters: [[WesternAnimation/HeyArnold Helga's ambiguously alcoholic mom, Miriam]], [[WesternAnimation/CaptainPlanetAndThePlaneteers Linka]], and [[WesternAnimation/{{Rugrats}} Phil, Lil, and Betty DeVille]], among others.
** Dexter's Dad was WesternAnimation/JohnnyBravo, [[WesternAnimation/CodenameKidsNextDoor Mr. Boss]], and a certain CandleJack, among others (JeffBennett).
** [[WesternAnimation/AnAmericanTail Tiger]] was Dee Dee's imaginary friend, Koosalagoopagoop, in "The Koos is Loose", "Koosalagoopagoop", and "Jeepers Creepers, Where is Peepers?".
** In Hungary, Dexter's first voice was [[Manga/DeathNote Near]] [[note]](not [[Film/TheHotChick Jessica Spencer]].)[[/note]].
*** In fact, Hungary holds a reunion for the ''Anime/SailorMoon'' cast: Dexter's first voice was Melvin; Dee Dee is Chibiusa; Dexter's first mom was Sailor Neptune; Mandark's first voice was Alan's second voice; and Dexter's second mom was Berthier, Karonite, Eugeal, Mimet, Telulu, PallaPalla, and Fisheye. Mandark's second voice is not Chad.
** Eddie Deezen is Mandark.
** Computress is basically Nicole from SonicSatAM. (KathSoucie)

* KeepCirculatingTheTapes: Bits of the first season were released on a now out-of-print VHS tape, the same goes for a collection of Genndy's favorite episodes. "Ego Trip" was released ''only'' on VHS, and that's out of print as well. The first season did get an official DVD release, but it does not include the banned "Dial M for Monkey" cartoon "Barbequor". Thankfully, the entire series (sans "Barbequor" and "Dexter's Rude Removal") is available on iTunes, and the entire first and second seasons (again barring "Barbequor") are available on Netflix.
** "Barbequor" is available on Netflix in the UK.
*** As of May 3rd 2015 all Episodes (Minus Barbequor) are on Hulu.
* MissingEpisode:
** ''Dos Boot'' (the name being a {{pun}} on Film/DasBoot) sometimes goes missing due to complaints about it GettingCrapPastTheRadar (the CreepyCrossdresser ending involving a Photoshop {{Expy}} and accusations the episode was a full-on criticism of the IT world).
** It is still available as KeepCirculatingTheTapes via Website/YouTube and Eastern European video sites.
** "Rude Removal" was one until [[http://www.youtube.com/watch?v=TLN_ka1ZSDg many years had past]].
** "Dial M for Monkey: Barbequor" isn't on the official Season 1 DVD, although it is available online in a few places.
* OfficialFanSubmittedContent: The script for "Dexter and Computress Get Mandark!", if [[StylisticSuck you couldn't tell already]].
* TheOtherDarrin:
** Dexter's VA went from Christine Cavanaugh to Candi Milo when the former retired from voice acting early on in the last two seasons.
** Dee Dee's VA continuously alternated between Allison Moore and Kat Cressida.
* ShrugOfGod: Even the series creator Genndy Tartakovsky isn't certain about what Dexter's [[WhatTheHellIsThatAccent bizarre accent]] is supposed to be.
* TalkingToHimself:
** Creator/FrankWelker does this whenever both Monkey and Quackor face off.
** Eddie Deezen voiced Mandark and his sister Lalavava.
* WritingByTheSeatOfYourPants: Genndy Tartakovsky, who was at the peak of his workaholism at the time, claims that the original show was produced so quickly that he didn't even see the finished product until it was on television.
* WriteWhoYouKnow: Dee Dee and Dexter's relationship was based on creator Genndy Tartakovsky and his brother Alex, who was always destroying Genndy's personal projects when they were younger.
