* ActingForTwo: Creator/BillyWest does a lot of the voices in the show, so this can happen at times.
* CrossDressingVoices:
** Literally, with the always versatile Creator/BillyWest, who voiced pre-op transgender barkeep Anita Bidet (and Anita back when she was a man as seen in "Please Be Genital").
** Pamela Segall Adlon voiced Milo and Jared Klimer.
* EditedForSyndication:
** In the episode "The Golden Child", an angry customer says "Go back to France, you stupid kraut!" On Creator/AdultSwim, the word "Kraut"[[note]]an ethnic slur used against Germans[[/note]] is muted. The line is uncensored on DVD, overseas broadcasts and the original WB airing ([[ScrewedByTheNetwork that is, if you ever saw it on there]]).
** On the TV version of "Get Off My Back", Mayor Bledsoe pulls out a gun and yells, "Move it, assholes!" with the last word partially muted out. On DVD, the line is "Move it, pussies!" with the last word uncensored.
* MissingEpisode:
** Because of how badly Creator/TheWB mishandled ''The Oblongs'', the last five episodes were never aired. It wouldn't be until Creator/AdultSwim picked up the show that the rest of the episodes would air in America (although Canada got the entire series, and all the episodes are available on DVD).
** If you lived in Australia around the time this show aired, it's worse, as the show was canceled ''halfway through'' '''''the first episode''''' due to complaints about the content.
* ScrewedByTheNetwork: Canceled in its original run after nine episodes on The WB. Attempts to keep it alive failed, though all 13 episodes eventually aired on Creator/AdultSwim, and a revival was said to be in the works for [adult swim] before they backed out due Angus Oblong revealing about it before contracts were signed.
* TransCharacterCisActor: Anita is a pre-op transgender woman, and she is voiced by the cisgender Creator/BillyWest.
* WhatCouldHaveBeen: Music/{{Sparks}} were amongst the bands whom auditioned to record the title theme, but were turned down by Angus in favor of Music/{{They Might Be Giants}}. Listen to it [[https://www.youtube.com/watch?v=-yNOKhjFF3A here.]] Other demos of auditioned bands such as Soul Coughing and Music/TheB52s have yet to surface.
** Creator/MarkHamill was Angus' choice for Bob's voice but was outed by the producers for Ferrell instead. Hamill would later voice Helga's father in "Milo Interrupted".
** A Halloween special that would've explained how Bob lost his limbs was considered for production by Creator/AdultSwim, but because Angus revealed too much about it before contracts were exchanged, they backed out at the last minute.
* WordOfGay: In an interview with the voice actors (Randy and Jason Sklar), they confirmed that Biff is gay while Chip is straight.
