Take That/Fan Works

"The rest of them consisted of security cameras, new channels, and re-runs of Sesame Street (one with a previously-banned appearance of Taylor Lautner)."
 * In Kira Is Justice:

""I wanted a Shinji that could go; DJ Croft? Who's that?""
 * Ultimate Sleepwalker: The New Dreams has a number of jabs aimed at things that bug the author:
 * Rick and Cyrus are discussing the notion that Spider Man got his powers from a spider-totem, and immediately dismiss it as the stupidest thing they've ever heard. They then discuss the only things that could be even stupider, such as the idea of Spider-Man unmasking himself.
 * Kenny mocks John Kricfalusi as a two-bit hack who creates shitty cartoons, and then criticizes Matt Groening for allowing The Simpsons for staying on the air years after it stopped being funny. He then proceeds to mock the (at the time) ridiculous notion that Family Guy had gone downhill or was plagiarizing The Simpsons.
 * The villainess Lullaby, who's a bleach-blonde slut with an absolutely atrocious singing voice, is a thematic representation of Britney Spears, Lindsay Lohan and Paris Hilton. Her fellow villainess Spectra is a thematic representation of revolutionary whackjobs like Che Guevara.
 * Red describes his List Of People I Want To Punch In The Face as including: Heather Mills, Jimmy Fallon, Richard Dawkins, Michael Moore, Ward Churchill, Ann Coulter, John Kricfalusi and Alex Rodriguez.
 * Both Red and Alyssa's father Elliot go on separate rants about Alex Rodriguez, giving him nicknames such as A-Fraud and A-Choker-In-The-Playoffs while ridiculing Rodriguez's absurdly bloated $25-million a year salary.
 * While watching a soccer game on TV, Red and Cyrus laugh at the notion that what they deem "the most boring game on the planet" has provoked everything from riots to murders to political upheaval to wars. When Cyrus asks why they're watching it, Red snarks that sometimes he likes to remind himself why America seceded from the British in the first place.
 * Many post-Deathly Hallows fanfics that ignore the epilogue still manage to fit the name Albus Severus in somewhere and have someone comment on how awful it it would be to actually be named that.
 * Chapter 9 of Deritine's (canon compliant to book 6) fanfic Warping Circumstances explains that the canon series is actually the result of Harry's failure to defeat Voldemort (in the universe of the fanfic). The "Powers That Be" were going to replay the major players in the propecy repeat it with "karmic debt". As the explanation of what would happen to who and why, it quickly becomes clear that the PTB, and by implication canon, are both horribly unfair and needlessly sadistic.
 * Luminosity: Edward and rational!Bella discuss what to name their child. They want to root her to the family, since she's going to be so rare a species that she may only see someone else like her once. The obvious way to do so is to combine Bella and Edward's mothers' names, but they decide that any combination of Renée and Esme sounds like a Pokémon.
 * The Return: The Return takes several potshots at Magical Girl series, and Sailor Moon in particular, Tropes (Fan Service outfits, Flowery Speeches about The Power of Love and Catchphrases, themed names. Did we mention it is Sailor Moon/Ranma Fuku Fic?
 * Shinji and Warhammer 40 K contains a Take That against Neon Exodus Evangelion.

"The Nod biker was a hundred meters away, with a dozen Nod soldiers between him and the man by Nigel's bike. A normal soldier, straight out of boot on his first day, would never have made that kind of shot with a pistol. Even an experienced target shooter might find it difficult.
 * TiberiumWars has a few of these, directed at the official Novelization of the game, including a choice jab at the novel's act of having a raw private dropping his loaded rifle and scoring a headshot at long range with a pistol - by having the same thing happen, except the man doing it is Havoc.

But that was why they called him "Havoc.""

""For those of you prepared to rant at me, there is one more chapter to this story, so unlike Gainax, you will actually get an explaination (sic) as part of the denouement.""
 * Thousand Shinji has one against the Gainax Ending of the original NGE:

"Deanna: Yep. My boys Tony, Adrian and Eric are identical triplets. After that experience, what sane person would want more?
 * Netraptor's Door Stopper series of Sonic the Hedgehog fanfiction "The Netraptor Sonicverse", contains a few generally subtle ones, generally towards the Sonic fandom. Perhaps one of the more notable examples would be Amy's subplot in "In Pursuit of Revenge", where she attempts to play Operation Jealousy by attemting to go out with three different people, Tails, Shadow, and Metal Sonic. Tails goes on one awkward date, but really is more interested with machines than anything else. Shadow lets her stay with him for awhile, but is far more busy with his own subplot and quickly grows tired of her. Metal Sonic (who had long since performed a Heel Face Turn), turns her down on the spot, albiet in the least rude way of the three, as he is far more interested in his subplot and taking care of his chao.
 * In Pretty Cure Heavy Metal, Shugo brings up the words you can't say on TV, Arson Murder and Jaywalking-style: "The only words that can't be spoken on television are the Seven Dirty Words, Goddamn, and Muhammad."
 * Mass Vexations has a few of these, given that it's a Mass Effect self-insert with quite a bit of Author Filibuster in its lampshading. The two most prominent are barbs aimed against a troll that attacked a large portion of Kung Fu Panda's fanfiction.net fandom because he disagreed with a pairing used in one person's story, and a barb at film critic Armond White.
 * The sequel adds Tommy Wiseau to the list of people that have had take thats in the Mass Vexations universe.
 * In Beautiful Destroyer Sailor Moon, Ami draws a picture of a female Ranma Saotome dressed as a Sailor Senshi, declares that it is stupid and immediately destroys it.
 * Progress makes a jab at the grimdark as fuck Cupcakes.
 * The one Twixie fic (it was about the competition, I forgot the name of it, it was on Eq D) had some fun with the creepy fan-made game "Story of the Blanks"
 * In Hunting the Unicorn, the Warblers constantly lampshade Kurt and Blaine's Tastes Like Diabetes relationship and lack of sex drive. A particularly memorable one is when someone says "We all know Blaine's going to wait until domestic-partnership" to sleep with Kurt. It becomes a Funny Aneurysm Moment when we find out that
 * Finishing the Fight has a scene near the end where Johnson and Keyes, who survived the events of Halo 3 in this story, reminisce about how Keyes was able to successfully rescue Johnson from the Covenant because she didn't make the mistakes that got her killed in the game.
 * In Keepers of the Elements, the author makes jabs at Twilight and Rebecca Black more than once. She also has one that takes a jab at the show Jon and Kate Plus Eight.

Heather: Jon and Kate?

Deanna: Like I said- what sane person would."

"L: There's the cultural stereotype of the Uke, who receives blow jobs from the Seme, which is seen as a privilege for the Uke. In return, the Seme gets to enter the Uke, which is a privilege for the Seme. However, it's considered degrading and low-status to be entered by another man, so supposedly nobody wants to be the Uke and the blow jobs are seen as a way to compensate the Uke for that humiliation and entice him into his role. I think you view yourself as the Seme and me as the Uke.
 * Fullmetal Lol makes extensive use of this trope toward Two and A Half Men. And a particularly hilarious example involving.
 * At one point in this Ed Edd and Eddy + Kingdom Hearts Fanfic: the bad guys blow up the world of Johnny Test.
 * The fanfic Chosen to Destroy. In the author's own words it "sums up my opinion on the Buffy Finale: Chosen". The fic is basically an expression of the author's hatred and contempt for Buffy (and to a lesser extent Angel), having the First destroy the entire world, what should have been the best demon fighting team ever (Xander, Giles, Willow and Faith) fail to form, and the First Good itself try (and fail) to set Buffy up to die, all because of Buffy's stupidity and ego.
 * During one of the glimpses inside Jade's mind in Queen of All Oni, the Aspect representing Love is stuffed in a barrel and thrown overboard, because "things are complicated enough; we don't need lovey-dopey stuff in the mix." Word of God is that this is meant to be a statement against unnecessary Shipping making stories more complicated than they need to be.
 * The Death Note Slash Fic Fever Dreams has a Take That at Boys Love Genre stereotypes:

Light: But those are just stereotypes. No relationship is really that simple unless there's at least one idiot involved."

"Impatient, I reached over and pulled down the quilt, revealing my stunning, immaculate, Adonis-like, statuesque, perfect husband. I wasn't quite sure when we had gotten married – probably about the same time I had gotten pregnant – but I was fairly certain we were married."
 * The Omake at the end of chapter 86 of the AU Naruto fanfiction The Greatest Thing You'll Ever Learn is one long Take That at Uke!Iruka, Purple Prose, Gratuitous Japanese, Wimpification, Petting Zoo People, Mister Seahorse and Yaoi Fangirls. The last part also counts as Self Deprecation, since the fic is written by a yaoi fangirl for yaoi fangirls.

"Hobbes: The vet shall attack you, young Vermin! Be afraid! Be very afraid! Think of that 1997 Batman movie with George Clooney! Terrifying! Not terrifying entertainment! Just terrifying!"
 * Calvin and Hobbes The Series, being very-self aware, has a few.
 * Among the scary things Calvin is shown in one episode include Dora.
 * "Wild Movie" starts with Calvin being disgusted by the mere prospect of a sequel to The Incredible Hulk.
 * When terrifying Sherman in "Sherman Goes to the Vet":

""Alternative title: Star Wars III: A Trip to the Dentist.""
 * Calvin spends part of "Hypercube" complaining about the Star Wars prequels.

"Hobbes: Are you all going to become Ben Stine stand-ins?"
 * After encountering Creepy Monotone clones in "Electronic Invasion":

""...no pagers, no iPods, no iPhones, no iTunes, no PDA, no laptops, digital cameras, no video cameras, no mini-DVD's… In fact, no technology that essentially does the exact same thing, but Apple says are each incredibly different in a scheme to make money.""
 * From Klein's long speech in "Attack of the Monsters":

"Sho:"And I got to tell that woman who wrote those trashy teenage vampire novels how much her books suck."
 * In Reconciliation, Sho talks about the perks of his job as the publicist for Hanako, a successful novelist, resulting in a Take That at Twilight.

Hanako:"I-I... I.... I remember that. She… she tried to tell you that you just 'didn’t get it,' and... and y-you said..."

Sho: “What’s to get? Vampires… don’t... s-sparkle! You hack!”"

"Light: You know, this is excellent proof that I'm not Kira. Ryuuzaki may be miserable and death-seeking but if I had been Kira then surely Matsuda would be dead by now."
 * Naruto Veangance Revelaitons does this far too often to list everything, but there are a few common categories.
 * Modern music, especially Justin Bieber and Lady Gaga. Despite his Author Avatar having similar hair to Bieber, a parenthetical note says "FUCK HIM HE SUCKS ALL MODERN MUSIC FUCKING SUCKS", which is the fic's Establishing Series Moment.
 * Religion and even agnostics. Ronan is weak against Bible verses, but he counters with the work of Richard Dawkins.
 * Any video games the author's stepbrother Benji likes, although other than this, there is no clear pattern. In a Villains Out Shopping moment, Madara and play Red Dead Redemption and In Famous.
 * Similarly, most kinds of food get this treatment, as well as any burgerrs besides those at In And Out. The villains use fast food restaurants to try to make everyone fat.
 * In the Service is itself a subtle but fairly long Take That against the tendency of Lyrical Nanoha fanfiction to make the Time-Space Administrative Bureau even more Mildly Military than it actually is in canon, or to outright forget it exists in favor of AU or semi-AU NanoFate stories. It also delivers a few more direct ones.
 * The offshoot story A Numbered Existence spends several chapters on the Huckebein from Magical Record Lyrical Nanoha Force, culminating in Jail Scaligetti's Combat Cyborgs curbstomping most of them in "What We Were Born To Do" and Veyron's belated acknowledgement that a large multi-planetary government has a whole lot more resources and people to throw at the Huckebein they could ever have dealt with in "Flipside".
 * A lesser but related example is Tre's taking one look at Cypha's oversized swords during their first encounter and dismissing them for being too easy to step inside the arc of. Tre then immediately demonstrates this problem by getting in close and nearly taking one of Cypha's hands off.
 * The concept of Mindlink Mates comes into play during a discussion of inter-Wolkenritter relationships, where it's revealed that because that trope would ensue the Wolkenritter can't have physical relationships with each other: no longer being an individual is scary.
 * All You Need Is Love has a take that at the Death Note fandom when Matsuda begins work on a soap opera based on the lives of the Kira taskforce in which he "reimagines" Light's character as poor wimpy Hikaru Imagay, the gay prostitute. Light is not amused:

Back to Take That.
