!!!''Girl Genius''

* It's [[Music/MCHammer Hammertime]] [[http://www.girlgeniusonline.com/comic.php?date=20101124 for Tarvek]]!
* [[http://www.girlgeniusonline.com/comic.php?date=20070822 The Heterodyne Castle has the grave of a guy called "Iscariot Heterodyne" with the line claiming him to be 'everyman's "friend"'. The quotes around friends are intentional, because the skulls of his "friends" are piled up right next to the grave, hinting him to be an notorious traitor]] like his namesake Judas Iscariot from the [[{{Literature/THEBIBLE}} New Testament]].
* [[http://www.girlgeniusonline.com/comic.php?date=20050328 This page]] sports an SteamPunk version of the hut of Literature/BabaYaga, with mechanic chicken feet and the egg joke.
* The very first page contains [[ComicBook/BuckGodotZapGunForHire The Winslow]].
* The wiki has a [[http://girlgenius.wikia.com/wiki/Shoutouts_to_other_webcomics whole list]] of the ones to other {{webcomics}}. [[http://www.girlgeniusonline.com/comic.php?date=20070319 In Mechanicsburg, there are signs]] advertising for [[Webcomic/WapsiSquare "exotic Wapsi Square"]], [[Webcomic/GunnerkriggCourt an inn called Gunnerkrigg Court]], [[Webcomic/SomethingPositive Professor Milholland's "Something Positive" tonic]], [[DominicDeegan a certain Dominic Deegan ("Sees all, tells all")]] and [[Webcomic/TheDevilsPanties "The Devil's Panties" lingerie]], among others... (Which get [[http://www.girlgeniusonline.com/comic.php?date=20070321 featured in the next strip]].)
** The science fair during the Cinderella parody includes more, in the form of displays. "Why the world needs YetAnotherFantasyGamerComic", "{{Goblins}}: Threat or food?" etcetera.
* Moxana is a shout out to both [[http://en.wikipedia.org/wiki/Moxon%27s_Master Moxon's Master]] and [[http://en.wikipedia.org/wiki/The_Turk The Turk]].
* Castle Heterodyne is equipped with [[Series/SaturdayNightLive Happy Fun Balls.]]
* Don't forget [[http://www.girlgeniusonline.com/comic.php?date=20070112 this strip,]] where several soldiers are attacked by a toothed trunk on legs with the words [[Literature/{{Discworld}} "The Amazing Pratchett"]] written on it.
* Another ''Literature/{{Discworld}}'' shout out is in the commentary: "[[http://www.girlgeniusonline.com/comic.php?date=20091207 ...kicking and screaming into the Century of the Fruitbat]]", hmm?
* [[Series/{{Blackadder}} "Don't drink the wine!"]]
* A fairly unsubtle reference to Gil rescuing Zola from [[ThePhantomOfTheOpera "some overly dramatic maniac who lived in the Paris Opera House."]]
* A skeleton of a giant spiky beast inside Castle Heterodyne was apparently a pet named [[WesternAnimation/CountDuckula Towser.]]
* The Unstoppable Higgs' [[http://www.girlgeniusonline.com/comic.php?date=20070330 cap indicates]] he's a crewman on the ship ''Anime/RozenMaiden''.
* When posing as Agatha's parents, PunchAndJudy went under the names [[Literature/TheBible Adam and Lilith Clay]].
* [[http://www.girlgeniusonline.com/comic.php?date=20090410 Turning]] a dread castle into... a ''[[Funny/TabletopGames Dread Gazebo]]''?
* [[Literature/TheWarOfTheWorlds Martian]] [[TripodTerror Tripods]] in the [[http://www.girlgeniusonline.com/comic.php?date=20040804 Baron's flashback]] and one of the Heterodynes' "[[http://www.girlgeniusonline.com/comic.php?date=20091014 My Vacation]]" pictures.
* One strip mentions an [[http://www.girlgeniusonline.com/comic.php?date=20090102 electric game]] [[VideoGame/DonkeyKong with the little man and the gorilla]]. It also mentions a boat ride with singing dolls. [[DisneyThemeParks What a small world it is.]]
* One scene shows a sign for both an X-ray and a [[WonderWoman Purple Ray]].
* Crazy A.I. with [[VideoGame/SystemShock SHODAN]]-like DramaticStutter.
* [[WesternAnimation/LooneyTunes "You don't expect a knife to sing opera, y'know?"]]
* When Zola first shows up claiming to be the new Heterodyne daughter, Agatha complains about her being a terrible, cheesy actor. Zola's very next line? "[[http://www.girlgeniusonline.com/comic.php?date=20070430 Yonder lies the castle of my father!]]", a quote from ''The Black Shield of Farnsworth'', which is generally considered one of the worst-delivered lines ever as the original actor had a very strong Bronx accent. usually rendered as "Yonda lies da castle of my fadda" to emphasise that Curtis was NotEvenBotheringWithTheAccent.
* In [[http://www.girlgeniusonline.com/comic.php?date=20060726 this strip]], [[AuthorAvatar Phil Foglio]] is shown singing Music/TheBeatles' "Ob-la-di, ob-la-da" with modified lyrics talking about oubliettes. Then, when the Jäger comes up through the floor, he asks [[Creator/DanielPinkwater "Nov shmoz ka-pop?"]]
* [[http://www.girlgeniusonline.com/comic.php?date=20090121 This strip]] has Major [[AnimalCrossing Resetti]] of the First Subterranean Mecha Mole Brigade.
* One of Gil's [[http://www.girlgeniusonline.com/comic.php?date=20080509 paper doll outfits]] has a [[Franchise/TheLegendOfZelda triforce]] symbol on the gauntlet.
* ''ComicBook/{{Buck Godot|Zap Gun for Hire}}'' [[http://www.girlgeniusonline.com/comic.php?date=20081031 T-shirt]]
* Gil's valet shares a last name with the employer of [[Literature/JeevesAndWooster the most famous gentleman's gentleman in fiction.]]
** And his ''first'' name with the high school that Phil Foglio attended.
* [[http://www.girlgeniusonline.com/comic.php?date=20110228 If one looks closely]], it appears that [[Webcomic/TheAdventuresOfDrMcNinja Doctor McNinja]] has an office in the hospital at Mechanicsburg. Which... explains a lot.
* [[DocRat Benjamin Rat]] appears in that same panel -- and "Dr. Rothfuss" obviously goes by [[TheKingkillerChronicle Patrick]]. (The Wise Man's Fear was published three days after that comic.)
* A poster at the Science Fair [[http://www.girlgeniusonline.com/comic.php?date=20081210 here]]: "Planet Earth: A ScaryGoRound we live on."
* [[http://www.girlgeniusonline.com/comic.php?date=20110502 Klaus]] [[Series/{{Firefly}} can kill you with the power of his mind.]]
* [[http://www.girlgeniusonline.com/comic.php?date=20070611 Is that]] [[Series/StargateSG1 Teal'c?]]
** [[CatchPhrase Indeed.]]
* [[http://www.girlgeniusonline.com/comic.php?date=20111017 Sir]] [[VideoGame/MediEvil Dan]]?
* The nefarious [[http://www.girlgeniusonline.com/comic.php?date=20051014 Prince Aaronev Wilhelm Sturmvoraus]] is visually based on Phil Foglio's fellow webcomic artist and ''Magazine/{{Dragon}} Magazine'' alum Aaron Williams, and his servant [[http://www.girlgeniusonline.com/comic.php?date=20051019 Nod]] ''is'' Williams's signature character, Webcomic/{{Nodwick}}. Also, Aaronev's dogsbody Artacz, who looks like a younger version of Artax from ''Nodwick'', only with a shorter moustache.
* [[invoked]] A [[GeniusBonus very obscure]] one: "''[[http://www.girlgeniusonline.com/comic.php?date=20070119 I'm a genius!]]'' Ha! Take ''that,'' [[http://en.wikipedia.org/wiki/Jean_Anthelme_Brillat-Savarin Brillat-Savarin!]]"
* When Zeetha and Agatha [[http://www.girlgeniusonline.com/comic.php?date=20120425 check out armors]], some of them look [[TabletopGame/{{Warhammer 40000}} kind of]] [[{{Galactus}} familiar]]...
-->'''Zeetha:''' [[VideoGame/{{Metroid}} What about this?]]\\
'''Agatha:''' No way -- [[SamusIsAGirl can't even tell you're a girl.]]
* [[http://www.girlgeniusonline.com/comic.php?date=20070808 In the Heterodyne Crypt]], there is a grave marked only "[[Franchise/{{Superman}} Zod]]".
* [[http://www.girlgeniusonline.com/comic.php?date=20081001 Theopholous is trying to track down his father's lost temple in India]], which somehow involves finding the "[[Franchise/MetalGear eye of the snake eater]]."
* The fake Jagermeister girls at Mamma Gkika's bar sing a modified version of the Andrews Sisters' song "Too Fat Polka."
** Their earlier song is a resetting of "The Beer Barrel Polka" and their show slash song for the "real" Jaegers seems to dance around "You can leave your hat on".
* When trying to [[http://www.girlgeniusonline.com/comic.php?date=20120629 escape a burning airship]], Tarvek and a Jäger almost quote the Series/MythBusters:
-->'''Jorgi''': "Dot dun sound like explosions..."
-->'''Tarvek''': "You're an expert?"
-->'''Jorgi''': "Sure, hyu bust op enough schtuff, hyu learns all kinds ov tings."
* Klaus can [[Film/LordOfTheRings walk into Mordor]] if he wants. [[http://www.girlgeniusonline.com/comic.php?date=20130306 Or Mechanicsburg.]]
* A [[http://www.girlgeniusonline.com/comic.php?date=20130408 shop in Mechanicsburg]] sells [[EldritchHorror Eldritch Meat]]. Today's special, [[Creator/HPLovecraft Shoggoth]].
* The Cinderella parody features [[http://www.girlgeniusonline.com/comic.php?date=20081219 music]] by the [[Music/PDQBach P.D.Q. Bach Engine]], whose operator bears an uncanny resemblance to Peter Schickele.
* Gil's Runcible Gun, which shoots [[FunnySpoon sporks]], references the "runcible spoon" mentioned in "The Owl and the Pussycat".
* The introduction of [[ThoseTwoGuys Those Three Jagers]] has them hanging from a gallows for days, which is likely a shout out to the late Robert Asprin's ''Myth Adventures'' series (Phil Foglio illustrated the comic version.)
* [[http://www.girlgeniusonline.com/comic.php?date=20031231 When Krosp first promises to help Agatha]], she asks if she needs to [[Literature/PussInBoots get it some boots]].
* When Agatha first enters Gil's laboratory on Castle Wulfenbach, we see [[Series/TheMuppetShow Dr. Bunsen Honeydew's]] [[https://www.youtube.com/watch?v=4QrelL9fOjY gorilla detector]]. Fittingly, there is a note attatched to it that reads, [[http://www.girlgeniusonline.com/comic.php?date=20040204 "NEEDS WORK"]].
* The [[http://www.girlgeniusonline.com/comic.php?date=20140623 Wyrm of Limmerick]] is the engine that made the [[Film/ANewHope "Konigsberg Run in less than twelve kilometers"]].
* One of the "[[http://www.girlgeniusonline.com/comic.php?date=20141024 many horrors used against us]]" is the... [[{{Portal}} Weighted Companion Cube]].

!!!Novelization

* When Rivet shows Agatha her collection of tools, Agatha finds a [[Series/DoctorWho sonic screwdriver]].
* The beginning of Chapter 6 in ''Agatha H. And The Clockwork Princess '' to a certain [[Literature/TheKingInYellow infamous play]] ......
-->'''Lucrezia''': You sir, should remove your pants.\\
'''Stranger''': Indeed?\\
'''Judy''': Indeed, it's time. We have all laid aside modesty but you.\\
'''Stranger''': I... wear no pants.\\
'''Lucrezia''': (Terrified, aside to Judy.) No pants? No pants!\\
