* AcceptableTargets: The Australians in the series are all portrayed as extroverted, popular, charismatic bullies who the main characters frequently scorn -- while [[SelfDeprecation the characters from New Zealand]] themselves aren't popular, confident, or lucky, and pretty much everyone either prefers Australians or forgets New Zealand even exists. All PlayedForLaughs, of course.
* BigLippedAlligatorMoment: The musical numbers that occur once or twice an episode, albeit on purpose. A notable one is when [[http://www.youtube.com/watch?v=w8S2iyJpuYA everyone starts singing conversational French]] after ordering a croissant.
** Perhaps the ultimate example is [[http://www.youtube.com/watch?v=shP1IRGigbo "Oh Dance, Baby"]], where Bret starts singing karaoke, entirely in Korean, about the difficulty of being in love. Or something.
*** The karaoke number is a reference to an earlier joke in the episode, where Murray got the guys an off-screen "gig" at open-mic karaoke night.
** Sometimes this even happens within a song, like with Dave's completely out-of-the-blue rap verse in ''Sugarlumps''.
** Interestingly, MushroomSamba song ''Prince of Parties'' is not one: in fact, it is actually probably the ''only'' song in the series that is directly referenced in a ''later episode'': "If you party with the party prince, you get two complimentary after-dinner mints!" sings Bret, wearing the costume from ''Prince of Parties'', in the second-season song ''Sugarlumps''. A BLAM referencing another BLAM... so meta...
*** All the sudden song numbers seem to exist in the same alternate reality, or rather in Bret and Jermaine's heads. WordOfGod says they have NoSocialSkills, but can communicate exactly what they're thinking through their songs.
** The wallpaper-skin reference from ''Freaky'' is shown to have actually happened shortly after the song ends.
* CultClassic: Though nominated for an Emmy, the show never achieved widespread fame or attention, perhaps due to the humor going against the mainstream, and the series ended after just two short seasons. Fortunately that didn't stop the show and band from gaining such a devoted fanbase that when the duo begins one of their infrequent tours, tickets typically sell out in ''minutes.''
* EarWorm: Too many to list. Everyone has their favourites.
* EnsembleDarkhorse: Murray, due to his tendency to dominate almost every scene he appears in.
** On an equal level of scene-stealing, Dave.
* FridgeBrilliance:
** In the song "Hurt Feelings", Jemaine laments about how his family forgot to call him on his birthday. His next line in the song is "The day after my birthday is not my birthday, mom." At first, this just seems tragically hilarious. However, New Zealand is 17-18 hours ahead of the USA's east coast. Ergo, she actually called him ''two'' days after his birthday!
** Upon listening again, you may realize that the rhyming structure of the song "Carol Brown" actually foreshadows the episode's ending! Keith [[spoiler: was nothing but a thief.]]
* HarsherInHindsight
** During his lifetime, "Bowie" was just a silly little pastiche written because they couldn't get [[Music/DavidBowie the man himself]] to cameo. Now that he's passed, it's more like an affectionate tribute after he [[AscendToAHigherPlaneOfExistence ascended to a higher plane of existence]].
** InUniverse. Jemaine dumps a woman with a fetish for Art Garfunkel impersonators, only to realize that the whole thing was pretty kinky for him too after it's too late.
* JerkassWoobie: Arguably, Albi the Racist Dragon
* NationalStereotypes: New Zealanders making fun of themselves, and New Zealanders making fun of Australians.
* StoicWoobie: Bret and Jemaine seem to experience nothing but failure over the course of the series, yet they're completely nonchalant up until the final episode.
* {{Tearjerker}}: now has [[Tearjerker/FlightOfTheConchords its own page]].
