* AccidentalAesop: Although most of the show's many Aesops are clearly presented and framed, some are shown rather than stated. For example, Rod and Nicky are proof that being great friends doesn't make two people good roommates.
* {{Anvilicious}}/SomeAnvilsNeedToBeDropped: Everyone's a little bit racist, and the Money Song in particular.
** Some of the overt "lessons" may be justified by the show's premise of being "Sesame Street for adults."
** One of the overall messages in the show though, that wasn't as lighthearted as the rest were presented was that not everyone knows their purpose. Some people may never find out what their calling is. And that's okay.
* BigLippedAlligatorMoment: "I'm Not Wearing Underwear Today"
** It ''does'' show how truly horribly unfunny Brian is.
* CrowningMusicOfAwesome: ''The internet is for porn, the internet is for porn... Why you think the net was born? Porn, porn, porn!''
** ''There's a fine, fine line between love and a waste of time...''
* EarWorm: Nearly every song, really.
* EnsembleDarkHorse: Rod and Nicky, as well as Trekkie. Mostly because their songs are the ones that have become the most [[MemeticMutation memetically widespread]] ("If You Were Gay" and "The Internet Is for Porn", respectively), and also because a lot of us grew up with the [[Series/SesameStreet characters that they're shamelessly parodying]].
* FamilyUnfriendlyAesop: "Everyone's a Little Bit Racist", "You Can Be as Loud as the Hell You Want (When You're Making Love)"
** Somewhat averted with "Everyone's a Little Bit Racist" in that the song ultimately preaches a higher level of tolerance and peace in the world through a "don't sweat the small stuff" mentality.
*** "Everyone's a Little Bit Racist" promotes a GreyAndGrayMorality view of racism, or maybe even BlackAndGrayMorality. Either of those is very different from the BlackAndWhiteMorality more common to racism in fiction, especially racism in fiction aimed at children like ''Series/SesameStreet''. The Aesop of "Everyone's a Little Bit Racist" isn't necessarily incorrect or immoral, but it is still family unfriendly.
*** BlackAndWhiteMorality about racism? That carries a lot of UnfortunateImplications. You're a little bit racist!
*** Also, given that racism is a learned behavior, stating that is the [[PeerPressureMakesYouEvil normal thing to be]] to children, who haven't necessarily learned it yet, would be very unfriendly. And that is assuming the premise is even true in the first place; if not, is someone who [[UnfortunateImplications isn't racist weird]]?
** Also the respective aesops of "The Money Song" and "For Now" are surprisingly family friendly.
** In a way, "Schadenfreude" is one of these too. ("Sure it's not nice ... but everybody does it!")
* FunnyAneurysmMoment: In the song "Purpose" Gary fears he's fulfilled his purpose and "is on a long slow walk to the grave". Gary Coleman is now dead.
** Sucks to be him.
*** One production by an independent theater in Minneapolis had a bit in the end where Gary goes to change the "For Rent" sign, falls down the stairs and dies. A new sign was put up that said "Now Hiring" in its place.
* HarsherInHindsight: Certainly having GaryColeman as a character at least feels a bit bittersweet since he died.
** Especially with everyone singing how much it sucks to be him in the opening number.
*** Worth mentioning: the day after his death was announced, his actress on Broadway made a special statement when the show was over, in tribute to him, to say "[[SincerityMode For me, at least, it has never sucked to be Gary Coleman on]] Theatre/AvenueQ."
* HilariousInHindsight: A ''Series/SesameStreet'' parody with a song called "The Internet Is for Porn". Fast forward to 2011, which Sesame Street's official Website/YouTube channel being hacked and pornographic videos being uploaded.
* HoYay: Nicky and Rod, of course! [[Series/SesameStreet Big surprise]] [[{{Expy}} there]]. [[{{Fanservice}} And then you have things like]] [[http://www.youtube.com/watch?v=H2r6-DmOoRY this]].
* MemeticMutation: TheInternetIsForPorn, a {{Trope Namer|s}}, and also very popular material for [=AMVs=] on Website/YouTube.
** Pick any anime character ever made ever, and there will be three different [=AMVs=] featuring them: 1. Them singing about their lack of underwear. 2. Them convincing their friend to come out of the closet, as well as a video of their friend trying to convince ''them''. 3. How much they [[JapaneseRanguage ruv]] someone, but also want to kill them in equal measure. there are no exceptions to this rule.
*** It doesn't need to be anime--this troper found the videos mentioned in 2 for Doctor Who, the Avengers, The Road To El Dorado (which is a cartoon but not anime)....
*** [[RecursiveParody Even applies to]] [[http://www.youtube.com/watch?v=yqcYJzc6lKw Bert and Ernie]].
* NightmareFuel: "Purpose".
* ThisIsYourPremiseOnDrugs
* ValuesDissonance: According to the "Everyone's a Little Bit Racist" song, intentionally telling jokes designed to insult a ethnic group, and using an ethnic slur while doing so, is only a "little racist", like unintentionally using an [[SocietyMarchesOn outdated term]] to refer to an ethnic group. And to be clear, it was "[[http://en.wikipedia.org/wiki/Polack Polack]]" jokes, and the teller was Gary Coleman, so there was no NWordPrivileges.
* WhatDoYouMeanItsNotForKids: Just because it's puppets doesn't mean it's for kids.
* TheWoobie: Everyone. They are '''fuzzy'''. And '''{{angst}}y'''. How can you not want to give them a hug?
** Even the ''porn addict'' is a woobie!
** The only exceptions are the Bad News Bears and Lucy (who are the closest things to actual villains in the story).
* {{Woolseyism}}: The Hungarian production of the show is considered the best Hungarian localization of any work in recent years. The most significant change was the replacement of Gary Coleman with Music/MichaelJackson; this was in part because Gary is all but unknown in the country, and mostly because Hungary has almost no black population and thus no one to play the role. In the original book, Jacko ended up on Avenue Q after two six-year-olds sued him for his entire estate; after the Pop King's death it was adjusted to say that he faked his own death to escape from his creditors.
** Also a bit of LuckyTranslation in the Hungarian production: Trekkie Monster is [[DubNameChange renamed]] Kuki Mumus. "Kuki" is a slang word for "penis", perfectly fitting his perverted personality, and it sounds exactly like "Cookie".
