* ActorAllusion:
** [[Creator/ScottMcNeil Zizrar, King of the Mole People]] who has a very similar voice to a certain iguana said at the end of Season 3, "[[WesternAnimation/KryptoTheSuperdog Man, I hate that kid and super dog!]]"
** [[Creator/JamesArnoldTaylor Johnny]] wants to be a [[Website/YouTube SnoobTube]] [[http://www.youtube.com/user/JamesArnoldTaylor sensation.]]
* AdoredByTheNetwork: Is constantly getting new episodes and reruns, despite having a ''huge'' {{Hatedom}}.
** It doesn't help that more well-liked shows were alledgedly ''cancelled'' to make room for it.
** It's just as bad in Canada, since Season 2 and beyond are produced for Cancon. However, Creator/{{Teletoon}} airs [[SeasonalRot Seasons 2 and 3]] over and over again, but enjoys the show as much as [[Creator/CartoonNetwork the American broadcaster]]. Season 1 has never aired. (Likely because Teletoon doesn't own the rights to the [[ScrewedByTheLawyers American-produced Season 1]]
* ChannelHop: From 4KidsTV (formally Kids WB) to Cartoon Network, made official with the coming of a fourth season.
* HeyItsThatGuy: A behind-the-scenes example: series creator Scott Fellows also created NedsDeclassifiedSchoolSurvivalGuide and BigTimeRush. '''Yes, really'''.
* HeyItsThatVoice: Johnny is voiced by Creator/JamesArnoldTaylor whose roles include Ratchet in VideoGame/RatchetAndClank and Wooldoor Sockbat in WesternAnimation/DrawnTogether.
** He was also formerly a [[VideoGame/FinalFantasyX blitzball player]].
*** He also pops up as [[ActingForTwo Mr. Mittens and Darth Vegan]].
** In Spain, Johnny is [[Series/ArrestedDevelopment George Michael]].
** Johnny's parents are WesternAnimation/MegaMan and [[WesternAnimation/MegaMan Roll]].
*** We might as well have a reunion with [[WesternAnimation/MegaMan Wily/Protoman]] as Mr. Black in the states.
** [[WesternAnimation/MyLittlePonyFriendshipIsMagic Gilda/Spitfire and Rainbow Dash/Applejack]] are [[CatchPhrase such geniuses]].
*** [[TheOtherDarrin In Season 2-4 anyway.]]
** Likewise Gill is Twilight's brother, Shining Armor or, going back even further, [[Anime/MonsterRancher Genki]].
** And their mother is so [[WesternAnimation/MyLittlePonyFriendshipIsMagic Great and Powerful]].
** Here's the Hungarian cast:
*** Johnny is [[WesternAnimation/TotalDramaIsland Noah]], [[WesternAnimation/GravityFalls Dipper]], and [[WesternAnimation/RegularShow Benson]].
*** Dukey is [[WesternAnimation/KingOfTheHill Bill Dautrieve]].
*** Susan and Mary are [[WesternAnimation/GravityFalls Mabel Pines]] and [[WesternAnimation/BobsBurgers Louise Belcher]].
* TheOtherDarrin:
** In Season Five, Louis Chirillo has been replaced with Creator/TrevorDevall. And it is EXTREMELY noticeable, with the entire voice pitch changed and Trevor struggling to keep the same inflections with obvious throat pain (going by the rough, scratchy noises). And for all his effort he just ends up sounding like Hugh Test.
** Mary Test was voiced by Brittney Wilson in Season One, [[Music/Heyocean Ashleigh Ball]] in Season Two-Four, and back to Brittney Wilson in Season Five after Ashleigh Ball left the show to [[WesternAnimation/MyLittlePonyFriendshipIsMagic voice Rainbow Dash and Applejack.]]
* ToiletHumor: "Dookie" is a juvenile euphemism for poop.
