* ApprovalOfGod: His parody of ''WebVideo/HowToBasic'', ''[[https://youtu.be/YNhMJ5_1yOI How To Make The Annoying Orange]]'' got approval from Mr. Basic himself.

* EnforcedMethodActing: ''[[https://www.youtube.com/watch?v=U_ety9JGwRI Prank Call #1: Tanning Salon]]'' is a real prank call.
* FakeBrit: Celery from ''[[https://www.youtube.com/watch?v=IcRguMhpQPQ Excess Cabbage]]'' and ''[[https://www.youtube.com/watch?v=56SA_C9o9VU Best Fiends Forever]]''.
* LongRunners: The series, having began in 2009, has being going on strong ever since. Even after the initial novelty of it has pretty much faded, the channel still continues to produce content to this day.
* TheMerch: There are official [[http://bit.ly/AOToys Annoying Orange toys]], [[http://annoyingorange.shop.bravadousa.com/ Annoying Orange shirts]], [[http://orange.tubeconic.com/ Annoying Orange stickers]], [[http://leprechaun.spreadshirt.com/ Liam the Leprechaun shirts]], and [[http://daneboe.spreadshirt.com/ Gagfilms shirts]].

* NonSingingVoice: Lady Pasta from ''[[https://www.youtube.com/watch?v=l3WPKznFvfk Lady Pasta]]'' and ''[[https://www.youtube.com/watch?v=tlBFB1zAfKU Annoying Orange Comedy Roast!]]'' is voiced by Lauren from ''WebVideo/TheKeyOfAwesome'', but the ''Lady Pasta'' [[http://bit.ly/LadyPasta song]] is sung by Sarah from [[WebVideo/AutoTuneTheNews The Gregory Brothers]].
* TheOtherDarrin:
** A rare ''prop'' example--Orange is always voiced by Daneboe, but in ''[[https://www.youtube.com/watch?v=0rY9FJhwjFg YouTube Meets Daneboe and The Annoying Orange!]]'', ''[[https://www.youtube.com/watch?v=zI1aZu1HpmM Super Bowl Football]]'', ''[[https://www.youtube.com/watch?v=H6IeASZZf1c Annoying Orange Saw]]'', and '''''WebVideo/{{Smosh}}''': [[https://www.youtube.com/watch?v=NL9lQ-DiL80 I LOST MY HAIR!]]''/''[[https://www.youtube.com/watch?v=xSFI5Q9kfXo I LOST MY HAIR! (EN ESPAÑOL)]]'', he's "played" by different oranges instead of the usual StockFootage.
** After playing Grapefruit for 10 years, Bobjenz finally stepped down from the role and was succeeded by Jon Bailey.
* QueerCharacterQueerActor: Non-binary Marshmallow is one of the many characters voiced by Daneboe, who in December 2023 came out as trans and uses they/them pronouns.
* ReferencedBy: [[Referencedby/AnnoyingOrange Has its own page]].
* ScrewedByTheNetwork: The TV show ended in March 2014, barely two years after it premiered. It was getting poor ratings anyway, though that could be owed to a lack of promotion on Cartoon Network's part and the fact that the novelty of the web series had since then faded.
* WhatCouldHaveBeen:
** A [[https://www.youtube.com/watch?v=_pWeGsG4fKY teaser]] for Liam the Leprechaun's {{spinoff}} advertises three new characters: Robot from Bobjenz's earlier ''Robot and Me'' series, some sort of laptop-using buddha, and the Terror-Dactyl. While the Terror-Dactyl did show up (in the [[https://www.youtube.com/watch?v=Yrb4L2F0sXw first episode]]), the other two characters have yet to appear alongside Liam.
** Jory Caron and Jon Paula from ''WebVideo/IsItAGoodIdeaToMicrowaveThis'' approached Daneboe for a possible introduction to one of their videos (specifically an experiment where they microwave an orange). Daneboe never returned their calls or emails.
