In Jackie Chan Adventures season 2 episode 9, Jade is shown to be a Big Eater, eating 5 hot dogs at a ballpark, and the game wasn't even FINISHED yet! Tohru lampshades this by saying he doesn't know where she puts it all which is saying something considering how much he eats.
(Aku appears before Jack) Jack: Aku! Aku:(droll) Yes, it is I, Samurai Jack. (rolls eyes) How incredibly observant you are. (Jack draws sword and runs at Aku, screaming) Aku: Oh, put that thing away, Samurai. We all know what's gonna happen. (Jack comes to a stop and watches Aku warily, sword still drawn) Aku: You'll swing your sword, I'll fly away and probably say something like "I'll be back, Samurai!" And then I'll flutter off over the horizon and we won't see each other for about a week. And then we'll do the same thing all over again. Jack:(looks guilty, then gets mad) Your word play will not trick me, villain! (lunges at him) Aku:No, wait! (turns into a bird and flutters off into the sky) I'll be back again, Samurai, you'll see! (flies over the horizon, laughing) (Jack stares after Aku, then rubs chin in thought) Aku:(reappears before Jack) See what I mean?
In Winx Club, the pixie Digit always thinks logically, but when the pixies are all hit with a homesickness spell, Digit can't come up with a logical explanation for why they have to return home when Lord Darkar needs to follow them back to their village to complete his evil scheme. Tecna (her bonded fairy) addresses this, noting that it's completely illogical for her to be saying this.
In "Believe It or Not, Joe's Walking on Air". Peter points out that his doctor's voice sounds an awful lot like his father-in-law's (the two characters share a voice actor). Mr. Pewterschmidt then enters the room from nowhere and proceeds to talk to Dr. Hartman, commenting on how they do have very similar voices, and how no one has ever noticed since they have not had any previous extended interaction.
In "A Fish Out of Water", after Peter shoots the talking fish Daggermouth, revealing that it's a robot, the fisherman Salty hops out from behind some stalagmites and explains his devious plot, spreading the Daggermouth legend and then getting rich off the merchandising, ending with:
Salty: And now I'm going to give you $50,000 to be on your way. Peter: But why? Salty: To keep your mouth shut! And because the longer we stay here, the more people are gonna question how a fisherman, with no engineering background, managed to build a sophisticated talking fish-robot.
In "Road To Rupert", Brian and Stewie have this exchange:
Brian: Besides, aren't you getting a little old for a teddy bear? Stewie:Brian, I'm 1! Brian:Still? Stewie: What?
In Season 6, Stewie brought up this point upon meeting Brian's son, "How can you have a 13 year old son when you yourself are only 7?" Brian immediately lampshades it with, "Well Stewie, if you don't like it, go on the internet and complain."
In the episode where Brian and Stewie join the Army, they set up for a cutaway and never go to it. Stewie even asks if they have a scene for that, guesses not, and they just go on.
In fact, when Stewie and Brian are waiting outside Cleveland's ex-wife's front door, they have a whole conversation about who should do the talking; "Well I don't know, I thought only immediate family members could understand you", etc, until finally an 'off-camera' voice shouts "Guys! We're still rolling!"
Done several times with Peter's chin. In "Ready, Willing, and Disabled", Peter is rubbing his chin in thought, he becomes surprised and promptly removes his chin and sticks it down his pants. Later in "PTV", the FCC wants to censor it due to it looking like a set of testicles.
In "Go, Stewie, Go", Stewie reveals he was pretending to be female through transvestism (to get a female only part) during a live scene of Jolly Farm.
Brian:(after the scene) Hey, why were they shooting that scene live? Stewie: Convenience. Brian: Yeah, but why'd they— Stewie:(interrupting) Let's not start pulling threads on this one...
From "Spies Reminiscent of Us":
Dan Aykroyd: Are there any local residents whom you've seen acting strangely? Stewie: Well, there's a pedophile up the street that nobody seems to be doing anything about, but it's mainly because he's so funny.
Peter is watching the news and a story comes on that gives him an idea to solve the problem-of-the-week. Then the news presenter says: "Coming up in the next half-hour: our in-depth look at conveniently placed news reports in television shows. But first, Peter - watch out for that skateboard." Peter then stands up and slips on a skateboard that had no reason to be there and wasn't there earlier.
Season finale. Peter Griffin and Glenn Quagmire are attending the wedding that was the centerpiece for the episode.
Quagmire: Wow. They really made it through the whole season. Hey Peter, can I have my own series, now? Peter: Quagmire, you're a rapist.
Cleveland's son starts playing guitar and singing a song in Spanish to his Mexican girlfriend, Cecilia, while Cleveland watches and jealously criticizes the situation under his breath:
Cleveland: Okay, he is not NOT fluent in Spanish. (Junior keeps singing) Cleveland: And he's NEVER played guitar. NEVER. (Junior keeps singing) Cleveland: (through gritted teeth) It is UNREALISTIC for him to suddenly gain these abilities!
The Simpsons uses this trope quite often, though sometimes in more subtle ways:
In the 1st Simpsons Clip show, Bart shakes a beer can in a paint shaker, which explodes (with a mushroom cloud) when Homer opens it, putting him in a coma. Grandpa explains that being in a coma, you relive past moments of your life, a lot like "one of those TV shows where they play clips from previous episodes." Here the authors acknowledge on their own behalf that a clip show is a lazy production with no new material. The episode is actually titled "So It's Come To This: A Simpsons Clip Show".
Bart becomes a "Junior Camper" (a Boy Scout): Lisa, Bart and Homer are watching an episode of Itchy and Scratchy, Bart notes that the scene was unrealistic. Lisa defends the cartoon, reminding Bart that cartoons don't need to be 100% accurate all the time. Though Homer is watching with them in the living room, as Lisa speaks, an intentionally mis-edited Homer is seen clearly walking outdoors past the window. This is an acknowledgment of the many inconsistencies that crop up throughout the show's history, and how the authors don't intend to make the show consistent.
In "Homer Loves Flanders", Bart is starting to wonder if Homer's newfound friendship with Ned Flanders will really last.
Lisa: Don't worry, Bart. It seems like every week something odd happens to the Simpsons. My advice is to ride it out, make the occasional smart-alec quip, and by next week we'll be back to where we started from, ready for another wacky adventure. Bart: Ay, caramba!! Lisa: That's the spirit. By the end, it seems like Ned and Homer will remain friends and Lisa's convinced that their wacky adventures will end. Cut to a scene taking place next week, Homer tells Ned Flanders to get lost.
Homer makes a comment about 'lousy Korean animation.' As he's saying it, his mouth disappears and reappears a few inches from his face, hanging in midair. There is a scene where Homer makes a comment about how bad at drawing Matt Groening is. A giant eraser appears and starts to rub him out. He yells that he 'takes it back' and then it is revealed that the eraser is just a sculpture being carried past. There is also an episode where a news report gives Homer an idea about how to solve a problem. He tells Lisa it's a good thing she turned the TV on at that moment. She says she didn't turn it on. They look back to the TV, which is now switched off, and say that neither of them turned it off either. Eerie music plays.
"Lemon of Troy" piles on the ShoutOuts to Homer's epics of the Trojan War: the name of the show's patriarch being an obvious, but not prominent example. Springfield's and Shelbyville's kids—ultimately, joined by their parents—feud over a disputed lemon tree. The grown-ups sneak Flanders' motor home into Shelbyville's cat-impound-lot fortress: by appearing to leave their vehicle abandoned in a hospital zone. As the tow truck drags them toward the forbidden destination, Homer Simpson exults, "No one in history has ever done anything this clever!"
A list of all of the Lampshade Hangings done — particularly in later seasons — could probably be a website in and of itself. The Simpsons Archive has a long list of "meta-references."
A hilarious one from Jimmy Neutron: in "The Junkman Cometh", as Jimmy, Sheen, and Carl are flying to the Moon, Sheen goes, "Hey Jimmy, how come we can fly through space in this rocket with our heads exposed? Shouldn't we not be able to breathe?" and Jimmy responds with "That's an excellent question, Sheen! Well, you see..." and as he explains it, the camera shifts to Carl, singing a song and drowning out Jimmy's explanation. Happens again on the return trip with another question.
Several episodes of Teenage Mutant Ninja Turtles revolved around adding a new mutant to the cast (such as the Frogs), and the main characters, who were notorious for breaking the Fourth Wall, would comment on the seemingly unending stream of mutated characters they seemed to run into.
One episode had one of the Turtles hang a lampshade on the fact that the episode's plot had meandered for about 20 minutes without bringing it any closer to a resolution, by telling the rest of the team "We'd better do something soon, or we'll have to show our first two-part episode!"
Another episode had a dinosaur causing (accidental) havoc in the city. As it ran away, one of the Turtles stated "We've got to chase after it" and ran off. One of the remaining Turtles asked "How come?" to which another replied: "Because if we didn't, it wouldn't be much of an episode". "...oh right".
The turtles mention Shredder stealing energy for the Technodrome, to which Michelangelo would say "Duh, they do that every episode."
Near the final seasons (after countless episodes where the Turtles have shut down the Technodrome), the Turtles sigh and say "we know, we know" step-by-step how they'll sneak inside and shut down the Technodrome, the same way they've had so many times before at this point.
Shredder mentions they kidnap April O'Neil... "We've done it so many times before."
Shredder and Krang were watching the use of a new military robot on the screen in the Technodrome. Krang wanted Shredder to attach a device to the robot that would let him control it. As he handed the device to Shredder, Shredder asked him "so, this is something you JUST HAPPENED to have laying around, huh?" to which Krang replied "We've got to keep the story moving".
In an episode, Michaelangelo watches many buildings falling to their ruin to which he reacts with the comment "The animators must have spent the entire season's budget on this single episode!" or something along those lines.
From the episode where Usagi is introduced; "He's from ancient Japan in an alternate reality. So naturally, he speaks English."
In the movie Turtles Forever, jokes poke fun at Breaking the Fourth Wall. For three times the 87 cartoon Raphael breaks the 4th wall, a villain from the 03 series, Hun, looks at the screen with a look that says "WTF" on his face. The 3rd time he gets mad and grabs Raphael and shouts "Why do you keep doing that? Who are you talking to? There's no one there!" Similarly, as an in-joke as to how the original Mirage turtles narrated certain story arcs, the 87 and 03 turtles actually hear the Mirage Leonardo narrating a fight and ask who he's talking to.
Also in Turtles Forever, Karai is inspecting 87's Shredder's Technodrome and berates the robotic foot soldiers for being "Easy breakable, no intelligence and Cartoonish"
In "The Deep South", Zoidberg's house burns to the ground... underwater. Zoidberg wails "How could this have happened?" and Hermes notes, "That's a very good question." Implicitly claiming responsibility, Bender picks his still-lit cigar out of the ruins and puffs on it, eliciting a cry of, "That just raises further questions!"
In "Why I Must Be a Crustacean In Love", Leela and Amy harp on Fry and Bender for being lazy, Leela making a point of Fry's beer belly. Amy points out that Bender's "belly" is bloated and his door won't close. She pauses, then adds, "...and that doesn't even make sense."
The Professor offers a long, elaborate, technically dubious, and absurd explanation for the appearance of "robot ghosts" in a castle, to which Hermes responds: "Of course! It was SO obvious!"
"Yes, that sequence of words I said made perfect sense."
In Season 1's "Hell is other Robots", the Robot Devil explains the conditions of a "Devil went down to Georgia"-like fiddle contest for Bender's soul.
Robot Devil: ...also you'll win a solid gold fiddle. Fry: Wouldn't a solid gold fiddle weigh hundreds of pounds and sound crummy? Robot Devil: Well, it's mostly for show.
In "Godfellas", after Bender is lost in space and hurled back to Earth by a god-like entity, he lands, unharmed, directly in front of Fry and Leela, who have been looking for him in the Himalayas. After Bender stands up, Leela announces that it is "by a wide margin the least likely thing that has EVER happened". (In the DVD commentary, the crew makes explicit reference to this being a lampshade hanging. "...And that's how we wrote our way out of THAT.")
In fact, there's a Lampshade Hanging in the very 1st episode: when both of Bender's arms fall off and he somehow puts them both back on, Fry simply comments, "I don't know how you did that." Very subtly hand waived in a later episode, when it is revealed that Bender's arms are capable of movement completely independent of the rest of his body, and seem to possess some measure of artificial intelligence.
After Bender is kidnapped and asks Fry and Leela for help, Leela is indecisive, saying she wishes they had two or three minutes to think about what to do. Cue commercial break.
Professor Farnsworth's cloned "son" remarks that faster than light travel is impossible to which Professor Farnsworth replies that scientists had previously increased the speed of light to circumvent that limitation. The clone's response was a nonchalant, "impossible." Originally, the clone character was intended to constantly lampshade the stranger aspects of the show, but the staff decided that would be annoying and dropped it.
After many episodes of mundane and unrelated quests that the crew have been pursuing and chasing throughout the seasons, Hermes remarks "Didn't we used to be a delivery company?" in Season 5.
In "Cartman's mom is still a dirty slut", a doctor mentions that a patient will be just fine as long as the power doesn't go out. Then it immediately does. He remarks "Who didn't see that coming from a mile away?"
In "Cancelled" the boys are negotiating with Joozian business executive aliens in a restaurant in space over the cancellation of Earth, which was revealed to be one big reality TV show for the rest of the universe. This was the 97th South Park episode.
Joozian Executive: "Yeah, a show should never go past a hundred episodes, or else it starts to get stale with ridiculously stupid plotlines and settings."
Joozian Waitress: "Here's your order of gespahtgaplachfenachenblah."
In both "Pandemic" and "Pandemic 2" Craig gets mad at the boys for dragging him into a bad situation. Craig says that normal kids don't get arrested by the government, sent to Peru to take out the government and then accidentally wind up in the land of the giants.
In "Cartmanland", Cartman gets sued when Kenny gets killed on one of the rides at his amusement part, and protests, "He dies all the time!"
Happens when Kenny berates Stan for crying over Kyle's imminent death, saying he dies all the time and no one cares. He is then promptly killed, and Stan doesn't seem to give a damn.
In the 1st Christmas episode, Kenny is alive at the end of the episode - the cast stands around silent and wonder aloud that something seems amiss. "THE END" appears, and Kenny jumps for joy.
Kenny is afraid of going into a wood shop class, despite the fact that "very few students are severely injured in shop class."
In the "Cartoon Wars" episodes the boys repeatedly take a break from making fun of Family Guy to say, "At least it's not all preachy and up its own ass with messages." Poking fun at the newer South Park episodes, which are just that. The lampshade managed to make the withering assessment of Family Guy elsewhere in the episode seem less mean spirited, which is sadly undercut by Matt and Trey's remarks about it in real life, often without the qualifier that they know their show is sometimes nowhere near as deep as they like to think, if it ever was.
In the same episode;
Cartman:(on the topic of cartoons ridiculing religion) How would you feel, Kyle, if there was a cartoon on television that made fun of Jews all the time? Kyle:(pointing at audience) Uh...
In "Cartman's Incredible Gift", Mrs. Crabtree is killed. The police remark that she was not a popular character and wouldn't be missed by the fans, as she was not in any recent episodes.
Episode 222, A history channel thanksgiving: The key-device to solve main conflict (Natalie Portman) is conveniently present to conveniently lead and guide their Keanu Reeves (the Pilgrim), just when he happens to plummet into the earth. Binding the two together to conveniently wrap the plot.
Random Scientist: "All over the country, people are reporting a shortage on stuffing...We don't think it's a coincidence." Head of the History channel: "You're telling me, that during a stuffing shortage this..Pilgrim drops down from space and got into a truck, driven by Natalie Portman!?" Another insignificant Scientist: "Look, if anyone knows something about stuffing, it's Natalie Portman!"
Stan: "Kyle! What the hell's going on this time?!"
Kyle: "I have no idea!"
The famous "They killed Kenny!" exchange was played with more than once during the show, before it fell into disuse after Kenny was Killed Off for Real. And then came back.
"Krazy Cripples" focused on Jimmy and Timmy for the A-story and Christopher Reeve and Gene Hackman for the B-story. Stan, Kyle, Cartman, and Kenny become Genre Savvy enough to just walk away from the craziness of both.
Kenny's many deaths are acknowledged by the character in "Mysterion Rises".
Tom Cruise: "By taking what Muhammad had, we would all be safe from ridicule. Like Tim Burton here. Imagine this, Tim: nobody could rip on you for all the rehashed movies you've made lately. There'd never be a TV show that pointed out you haven't had an original thought since Beetlejuice. And you put Johnny Depp and the same crappy music in every film. And if you're that in love with Johnny Depp you should just have sex with him already. A TV show could never say that!"
In "Cartman Joins NAMBLA" (episode #53), when the new baby Kenny shows up:
Mr. McCormick: "God, this must be the 50th time this has happened."
Mrs. McCormick: "Fifty-second."
In "It Hits the Fan" they mock the controversy that just because someone swears on television doesn't mean it harms society.
In the Merrie Melodies short "The Scarlet Pumpernickel", Daffy tries to jump from a window onto his horse's saddle, but falls on the ground with a crash. He comments, "That never happens to Errol Flynn."note Justified in that this was a script Daffy was reading to a director.
After Marty McFly keeps running into various ancestors of Biff Tannen (traveling not only through time, but space as well!) in Back to the FutureThe Animated Series, he exclaims: "Is there a Tannen in every century?"
The Venture Bros. frequently points out the fact that henchmen #21 and #24 never die. For example; in the episode "Lepidopterists", #21 and #24 point out to Henchman #1 that they would never die, unlike the other henchmen. Also, in the same episode, Dr. Girlfriend asked Monarch why he keeps using 21 and 24, he replied "I know it sounds crazy, but they both have that rare blend of 'expendable' and 'invulnerable' that makes for a perfect henchman."
Which turns into morbid Foreshadowing when #24 dies in the season finale. Though, the unlikely situation leading to that is lampshaded by #21 asking his friend why he even buckled up when they weren't going anywhere in the car.
Megas XLR loves doing this through the use of signs, particularly with buildings about to be destroyed.
Several include "Conveniently Empty Building," "This Building is Scheduled for Demolition Anyway," and "Explosions and Shrapnel Factory".
Coop's megaweapon button, which always reads something along the lines of: "Super Destructor Mode" or "Being Hit With A Giant Taser? Press Here". In one case the lampshade hanging is enormous: the same thing happens, and then a bit later during the same fight, Coop presses the button again, it reads: "Exactly the same button Coop just used like five minutes ago", but for a different effect.
Drawn Together is full of these types of jokes, frequently insulting the show itself for comedic effect. An example is in the episode "Little Orphan Hero", where Spanky, Princess Clara, Foxy, Toot, and Ling Ling try to help a suicidal quadriplegic end his miserable life. When said man reveals himself to be an undercover cop intending to arrest them for attempting to 'murder' him and that the entire area is surrounded by similar quadriplegic cops (importantly for the joke, all with horrible pun names, like Bob, who's waiting in the water) intending to arrest them, Spanky sighs and says, "This is so stupid, it's like some retarded 3rd grader wrote this."
David Xanatos needs some way to lure the magical Coyote to him. To do this, he puts Goliath, Angela, Elisa, and Bronx in a Death Trap to make the being intervene to save them. Xanatos and his robot lovingly describe the trap to the heroes and Xanatos cannot resist noting, "It's my first stab at clichéd villainy; how am I doing?"
Xanatos and Demona creates a new Gargoyle, by putting the remains of three back together, who were destroyed in stone form. When the Gargoyle mixup began to live again, Xanatos shouted with great joy: "It's alive! IT'S ALIVE!" Followed by: "I Always Wanted to Say That."
In the series finale, Toph hangs her own lampshade on this by wanting to go with Zuko for her Character Development "field trip". And after trying to do so, but having Zuko out-angst her parent-wise, she mutters, "Worst. Field trip. Ever."
"The Ember Island Players", to the extent of lampshading the lampshade. When Katara asks if it's really wise to go see a play about themselves, Sokka responds, "Come on, a day at the theater? This is the kind of wacky, time-wasting nonsense I've been missing!"
The main characters get invited to a party for the Earth King's bear, and are surprised that it is just a bear and not a bear crossed with another animal.
Hammerspace does not make sense to Katara. "Where'd you get that?"
Toph eventually gets fed up with one of the series' best Running Gags ("It sounds like a piece of paper. I mean, seriously, what's with you people?! I'm BLIND!") They write an apology letter from Toph to Katara, forgetting that Toph can't write. Aang proposes they do it the other way around, with Sokka snarking "I think we're gonna run into a similar problem."
The Mighty Ducks had a scene where after two of the six main characters have been captured by the Villain of the Week and two more have been sucked through the TV into an alternate dimension, one of the remaining characters says, "If we keep losing teammates, this show's gonna be called The Mighty Duck". Nosedive also tends to cross the line into No Fourth Wall territory, as he's been shown to hear flashback music and have enough Genre Savviness to recognize a really friggin' Obvious Trap.
"Suction Cup Symphony". SpongeBob annoys Squidward in Squidward's house. Randomly, Patrick just appears in the room. When Squidward asks why Patrick's there, he simply goes, "I'm funny"
Patrick and SpongeBob are sitting by a campfire:
SpongeBob: At least it's warm by the fire. Patrick: Hey, if we're underwater, how can there be a — (fire promptly goes out) I'm scared.
In "Fools in April", Patrick is wearing SpongeBob's hat (Squidward only sees the hat and thinks it's him). When asked why he's wearing it (as there's no reason to other than to set up the scene), he simply says, "I don't know."
SpongeBob is trying to stop Patrick from doing some really nonsensical, dangerous things, and when asked why he's doing them, Patrick responds...
Patrick: SpongeBob, you can't expect my normal garden-variety brand of stupidity. I like to mix it up, keep you on your toes.
When Patchy the Pirate sends a letter to SpongeBob inviting him to a party, the ink is smeared. SpongeBob comments "Whoever sent this letter is obviously unaware of the physical limitations of living underwater!", before throwing it into a fire.
Mr. Krabs once called SpongeBob a "loony loofah", possibly intended to lampshade the fact that SpongeBob's a kitchen sponge.
The Narrator: Suddenly, Ned's zipper is hit by a meteor, bitten by radioactive bugs, bombarded with unknown nuclear energies and struck with the power of the Norse Gods! Ned: Wow. That almost never happens.
Ron being attacked for the third time by birds in "Cat Trouble" (the third time practically comes out of nowhere):
Ron: (being pecked) AHHH! THIS IS JUST SO RANDOM!!!
Another from the same episode. Ron is lampshading an offscreen Noodle Incident that involves Kim trying to fix up a hand-me down broken down cat her father gave her. Things aren't working out at all...somehow Ron is entangled in wires. Poor Ron, if only he knew Rule of Funny.
Ron: Wait a minute?! I wasn't even helping! How did this happen?!
Shego, from The Movie: "You know, one of these days, we reeeeally need to take that hairdryer from her."
Kim gets her own in "A Sitch in Time" when she corners the villains, but they boast they have a advantage against her, being she's outnumbered (as Drakken sneaks up from behind her). Drakken has his own Lampshade to this too.
Shego: "If the pit is bottomless, than how do you fill it with water?"
Drakken: "IT'S VERY VERY DEEP, ALL RIGHT?!?"
Kim lampshades her habit of blowing up Drakken's lair in the episode "Bad Boy". The episode's main conflict - Ron absorbing Drakken's evil - is resolved with Drakken's lair and Ron's Doomsday Device still intact. Drakken crows about this, but Kim just says "I think we both know what happens next." Cut to Kim and Ron flying away from the exploding lair.
Gosalyn: That plot doesn't sound so cliché when it's happening to you!
Lilo & Stitch: The Series, episode "Poxy": Jumba brings the heavily modified dune buggy into his and Pleakley's room to prepare for Lilo and Stitch's journey inside of Pleakley to retrieve the experiment making him sick. While Jumba is explaining the plan, Lilo asks, "Hey, how'd you get the buggy in here?" Jumba responds, "Oh, simple... um, is not important."
Dark Danny pointing out how obvious his Paper-Thin Disguise was. Also in the same one where Clockwork points out Dark Danny (in disguise as his younger, non-evil self) and says something like, "See? He's back to his proper time and apparently not evil." David Carradine, you rock.
At the end of "Reign Storm", Danny doesn't feel satisfied, given that a lot of thingsweren't adequately resolved, and this concerns him. Sam only shuts him up by saying he saved the day, and he should relax for now.
In "A Mile in My Shoes", Cosmo and Wanda (while in goldfish form, inside their bowl) are preparing for a romantic dinner, and Cosmo attempts to light the candles on the dinner table by rubbing two magic wands together. Timmy walks into the room and asks the couple, "What's new?" just as Cosmo succeeds in lighting the candle. Wanda glances at the flame skeptically, then answers, "Um, the laws of physics?" To be fair, he was using magic wands.
A later feat is to lampshade the frequent use of the Idiot Ball.
Wanda: Don't do something stupid. *poof away* Timmy: Why would she say that? *looks at Cosmo* Cosmo: I don't know. Let's do something stupid. Timmy: Ok!
In an episode of Superman: The Animated Series three members of The Legion of Super Heroes follow Brainiac back a thousand years in time to stop him killing a teenaged Clark. Saturn Girl says Clark will need a disguise, to which Clark says "like a pair of glasses would fool anyone". Chameleon Boy a few moments later shapeshifts into Superman to illustrate what they were saying Clark was going to become, to which Clark says "Red underpants? Now I know you are crazy!"
In the first episode of the adult animated series Mission Hill, Andy's sometime girlfriend Gwen comments on Andy's old plan for an animated TV series for adults: "Oh God, not another animated series."
Double points given, in that Mission Hill was greenlit because the WB (later the CW) wanted their own animated show like many other channels at the time (South Park/Comedy Central, The Simpsons/Fox), but ignored what their demographic was.
Wonder Woman blocks a lightning bolt from Weather Wizard with her reflective (metal) wristbands. The Flash is quick to point out: "There are so many reasons why that shouldn't have worked."
Immediately afterward, she uses a wristband to reflect a lightning bolt back at Weather Wizard, knocking him over. It's a good thing the lampshade was already hanging.
Right before crashing his jet ski into a group of charging soldiers, Aquaman manages to leap off of it and onto the back of a killer whale which coincidentally popped up out of the water at the same moment.
Green Lantern: I saw it but I still don't believe it.
In the episode of The Batman called "Q&A", the villain is re-enacting a game show at which he lost years before, with the people who were hosting the game being forced to play it, with death the penalty for losing. Right after he tells them the rules of the game, he says, "At this point in the show we would usually break for a word from our sponsor... don't you wish." Cut to real-life commercial.
In an episode of Archer, the following dialog is spoken after Archer pulls out a grenade after a threesome:
Lana: Where'd you get a grenade? Archer: Hangin' from the lampshade! Lana: Wait, what?
And in an earlier episode:
Archer: God, I said the cap slips off the poison pen for no reason, didn't I?! Cyril: I know, I know, but I just assumed that if anything bad happened it—it would've been— Archer: No, do not say the Chekhov gun, Cyril! THAT, sir, is a facile argument! Wodehouse: Also woefully esoteric.
KaBlam! does this a lot with its stars, Henry and June. This includes explaining the "anvil accordion squash", "the bongo run", "cartoons not feeling pain (except Henry)", and so many others that we lost count.
In another episode, when Robbie is framed as a criminal mastermind, the prosecutor mocks his story of being knocked out and waking up with a blaster in his hands. "This isn't some Saturday morning cartoon show!"
During the "Six Forgotten Warriors" arc, Kingpin reveals his intention to conquer the world to a captured Spider-Man, who doesn't take him very seriously. "Kingpin, now you're starting to sound like a Saturday morning cartoon villain."
Johnny Test loves hanging lampshades in regard to stories and their own recurring plotlines. In Johnny Boat Racers after being joined in racing a rowing crew by Mr. Black, Mr. White, his sisters, and Bling Bling Boy, Johnny lampshades the fact that they get joined by at least two more, one of them a talking cat. Moments later Mr. Mittens and Steve McCool. Also, Bling Bling Boy lampshades the fact that he'll never get Susan to kiss him by winning the race, but likes being a part of them anyway because they're always fun.
In an episode of The Spectacular Spider Man, Black Cat tries to persuade Spidey to join her in criminal pursuits, and when he's in his Black Costume at their next meeting, she immediately assumes that he's agreed to her proposal and made an Evil Costume Switch.
Pinkie: When I was a little filly and the sun was going dooooown... Twilight: Tell me she's not... Pinkie: The darkness and the shadows, they would always make me frooooown... Rarity: She is.
In the first season finale, Rarity objects to allowing Spike, a male character, in to the room while the female ponies were getting dressed, to which Applejack responded "Beg pardon, Rarity, but, uh, we don't normally wear clothes." (Sez the pony who normally wears a cowboy hat.)
In the episode "It's About Time," While consulting Madame Pinkie in her tent, Twilight has a flower pot fall on her head. Pinkie immediately lampshades this by asking "Where did that come from?"
