April Fools’ Day pranks on the internet indicate that we’re not attempting to idiot one another day by day in net design anyway. Certainly, certainly one of my favourite feedback I obtained on an article was, “I can’t consider my eyes!” You shouldn’t, since net design depends on fooling the person’s mind by manipulating the way in which we course of visible data by way of Gestalt legal guidelines, which make a web site really feel actual.
April Fools’ Day on the internet exemplifies what thinker Jean Baudrillard referred to as a deterrence machine — a single day on the calendar to have a good time humorous pretend information is sort of a theme park designed to make the pretend constructs past its gates appear actual by comparability. And oftentimes, the net pranks on April 1st are indistinguishable from the bizarreness that ensues all yr spherical within the “actual” digital world.
Actual issues that regarded like April Fools’ pranks
Tech has a historical past of April Fools’ Day bulletins that remind me of what Philip Ok. Dick referred to as “pretend fakes,” rising yearly like actual animals surreptitiously changing the pretend ones at Disneyland.
As an illustration, in 2004, folks famously thought Gmail was an April Fools’ joke because it was introduced on April 1st.
And on April Fools’ Day in 2013, lengthy earlier than the present technology of AI, Tom Murphy introduced an AI that learns to play NES video games. It was the true deal, regardless that he revealed the analysis paper and supply code on “SIGBOVIK 2013, an April 1st convention that often publishes pretend analysis. Mine is actual!” In Tom’s demo, the AI even devised the technique of indefinitely pausing Tetris, as a result of in that recreation on NES, “The one method to win is to not play.”
To present a extra private instance of actual tech that might be mistaken for an April Fools’ joke, my article on pure CSS collision detection was revealed on April 1st, 2025, my native time. I used to be amused when somebody commented that utilizing min to detect if a paddle was in vary of a ball appeared like a intelligent hack that “brings up the query: Ought to recreation logic be completed in CSS?” In fact it shouldn’t! I wasn’t critically proposing this as the way forward for net recreation growth.
I replied that if the commenter can take the thought critically for a minute, it’s a testomony to how far CSS has come as a language. It appears even funnier in hindsight, now that the vary syntax has come to fashion queries, which means we now not want the min hack. So, perhaps everybody ought to make video games in CSS now, if the min hack was the one deal breaker (I child as a result of I really like).
My CSS collision detection demo had a resurgence in recognition just lately, when Chris Coyier selected it as a picked Pen. And in that CodePen, a remark once more made me giggle: “Can or not it’s multiplayer/on-line?” But, as soon as I finished laughing, I discovered myself attempting to get a multiplayer mode working. Whether or not I can or not, I assume the joke’s on me for taking CSS hacking too critically.
The factor is, a lot of what we now have on the internet this yr appeared unthinkable final yr.
Even the story of the origin of April Idiot’s Day seems like a geeky April Fools’ joke — the main concept is that the Fifteenth-century equal of the Y2K bug had some silly folks incorrectly celebrating the brand new yr on April 1st when the Pope modified the calendars in France from the Julian Calendar to the Gregorian Calendar. And — April Fools’ once more! — that’s a legend no person has been in a position to show occurred.
However whichever means you’re feeling in regards to the fixed disruptions on the coronary heart of the evolution of tech, the disruptions work like pranks by flipping widespread narratives on their heads in the identical means April Fools’ Day does. With that in thoughts, let’s undergo historical past with an eye fixed for exploring the core of fact contained in the jokes of April Fools’ Days handed.
Observe: These are the historic pranks I think about the highest 10 most noteworthy, moderately than the “finest.” You’ll see that a few of them crossed the road and/or backfired.
Google April Fools’ video games
Google is well-known for its April Fools’ pranks, however they’ve additionally traditionally blurred the road between pranks and options. For instance, on April 1st 2019, Google launched a non permanent easter egg that reworked Google Calendar right into a House Invaders recreation. It was such a cool “joke” that these days, there’s a Chrome extension that provides an analogous expertise, turning your Google Calendar right into a Breakout recreation. This extension additionally affords the choice to truly delete objects that your ball hit out of your calendar on the finish of a recreation.
On April Fools’ Day the identical yr as the unique calendar recreation, Google additionally launched a characteristic that allowed Google Maps customers to play Snake on maps.
Private Sidenote: The Google gag impressed an unreleased recreation I as soon as made with an overworld that’s a gamified calendar, through which your character is attempting to keep away from an abusive accomplice by creating excuses to not be at residence similtaneously their accomplice, however that’s a bit of darkish for April Fools’.
Prank npm packages
In March 2016, a legit — if arguably trivial — eleven-line package deal was deleted from the npm registry after its creator determined to boycott npm. Seems that deletion disrupted massive firms whose code relied on the left-pad package deal and this prompted npm to change its insurance policies on which packages might be deleted. I point out this as a result of the humour of the npm packages launched as jokes typically revolves round poking enjoyable at JavaScript builders’ overuse of dependencies that may not be wanted.
Here’s a 0kb npm package deal referred to as vanilla-javascript and a web page for the Vanilla JS “framework” that’s all the time 0kb, regardless of which options you add to the “bundle.” It lists all of the JavaScript frameworks as “plugins.” A few of the dependent packages for vanilla-javascript are fairly humorous. I like false-js, which ensures true and false are outlined correctly. The library might be initialized with the settings disableAprilFoolsSideEffects, definitelyDisableAprilFoolsSideEffects, and strictDisableAprilFoolsSideEffectsCheck. In case you learn the supply code, there’s a remark saying, “Haha, this code is obfuscated, you’ll by no means work out what occurs on April Fools.”
There may be additionally this ineffective library to get the present day. It appears believable until you look fastidiously on the web site and the outline: “This package deal is ephemeral for April Fools’ Day and will probably be eliminated sooner or later.“ The testimonials from fictional time-traveling characters are additionally a little bit of a giveaway, and it’s important to love that he up to date it day by day for months, “as a result of… why not? 🤷♂️”
Extra “horrible npm packages” for April Fools’ are right here.
aprilFools.css
There’s one other class of dependencies which might be practical however used for enjoying April Fools pranks. As an illustration, aprilFools.css by Wes Bos, which has a remark on the prime saying:
/*
I assume no accountability for offended co-workers or misplaced productiveness
Put these CSS definitons into your co-workers Customized.css file.
They are going to be utilized to each web site they go to in addition to their developer instruments.
*/It does issues like use CSS transforms to show the web page the other way up.
It strikes me that following the recommendation within the feedback might be a slippery slope to a darkish place of office bullying, when you had been to attempt it on the flawed coworker, simply because they left their laptop unlocked. As Chris Coyier identified in his submit on sensible jokes within the browser:
“Truthful warning on these items… you gotta be tasteful. Placing somebody’s stapler within the jello is fairly hilarious except it’s by some means a household heirloom, or it’s somebody who’s been the goal of a bit of an excessive amount of workplace prankery to the purpose it isn’t humorous anymore.”
April Idiot’s pranks utilizing VS Code Extensions
Whereas we’re on the subject of conduct that blurs the road between pranks and office bullying, let’s speak about this listing of VS Code Extensions that might be used to prank a coworker by inflicting their code editor UI to behave unexpectedly. A lot of the examples sound humorous and innocent, like having the IDE intermittently pop up “Dad Jokes” or make humorous sounds when typing. Altering the code editor to resemble Slack utilizing a theme can be humorous.
Then there’s the final instance that made me do a double-take: “Think about hitting CTRL + S to avoid wasting your work after which it will get erased!” Yeah, if I had been interviewing somebody and so they talked about they think about this a humorous joke, I might finish the interview there. And if anybody ever does this to me, I’m going to HR.
Pranks by the W3C
I don’t consider the W3C as having a humorousness, though I assume getting me enthusiastic about HTML imports again within the day, solely to discontinue them, was humorous in hindsight, if in case you have a darkish humorousness. Nonetheless, they’ve posted pranks on their official web site, resembling restyling to make their web page appear like a nineties GeoCities web site in 2012, or claiming they had been reviving the tag in 2021. There’s a theme of enjoying on the nostalgia of individuals my age who need this stuff to be actual.
Sidenote: If you need extra Nineties web experiences, the sport Hypnospace Outlaw, set on a retro web in another 1999, may be up your alley.
Different websites through the years have performed an analogous joke, which might by no means fail to allure an old-timer like me who remembers utilizing an online like this on the public library, again when the web was too costly for my household to afford at residence.
StackOverflow retro restyle
I can’t get sufficient of those nostalgia journeys, so right here’s what StackOverflow regarded like on April Fools’ Day in 2019. They turned the positioning “full GeoCities” for enjoyable. But all the pieces comes full circle. Now StackOverflow itself appears destined to grow to be as fossilized as GeoCities. Even so, the positioning is presently making an attempt a brand new, actual redesign to survive moderately than for enjoyable. It’s sobering to think about that perhaps the one StackOverflow expertise for the subsequent technology of coders will probably be if ChatGPT will get a StackOverflow restyle on a future April Fools’.
Stack Egg
Whereas we’re on the subject of StackOverflow, their Stack Egg prank from 2015 was very cool, nevertheless it may win my award for essentially the most over-engineered April Fools’ prank that triggered essentially the most severe issues for a web site. The premise was one other Nineties throwback, this time to the nineties Tamagotchi craze.
The thought, because the creator describes it, was that each web site on the Stack Alternate community would have its personal “Stack Egg,” representing that web site. The aim was to collaboratively maintain your metaphorical “web site” alive utilizing hypothetical actions named after actual actions on the positioning, resembling upvotes to feed the Tamagotchi, and evaluate actions to wash up the poop so the Tamagotchi doesn’t get sick.
It was a nifty idea, though like Google’s April Fools’ video games, it’s extra neat than laugh-out-loud humorous. The half that does make me giggle — I don’t really feel too responsible saying it because it was greater than a decade in the past — was that it is a recreation about conserving the web sites alive, and it inadvertently DDoS-ed its personal web sites and took down the entire StackExchange community.
And but, the creators thought the truth that that they had the foresight to implement a characteristic flag that allowed switching it off meant this was a case research in “Operational Excellence in AFPs (April Fools’ Pranks).” Yep, that’s an precise article revealed in a peer-reviewed journal. Based on the article, the engineers concerned pushed a repair about two hours later to salvage the prank. Code Golf was the winner of the sport, in case you’re questioning. Based on the identical submit that introduced the winner, “it’s certainly not designed to resist exploits,” and within the two days the characteristic was reside, customers found a vulnerability that was “near voting fraud.”
I discussed the over-engineering, so right here’s the half that makes the unintentional punchline even funnier: moderately than investing extra time guarding in opposition to the fundamentals, resembling not bringing down the web site and contemplating safety, the creator frolicked making his personal Turing-complete language to deal with the LCD-style animations, “as a result of I needed to! Making a programming language is enjoyable.”
That’s such a classically geeky method to prioritize!
Google Mic Drop
If Stack Egg created essentially the most points I’ve ever heard of for a web site that created the prank, essentially the most mean-spirited high-profile UI prank — which triggered essentially the most issues for customers — needs to be Google Mic Drop. It dropped (pun meant) on April Fools’ Day 2016, shortly after Google modified its motto from “don’t be evil” to “do the appropriate factor.” Then, they promptly redefined the “proper factor” as sabotaging folks’s skilled reputations with a minion GIF.
Google added a button, good and near the common “Ship” button in Gmail, that will ship a farewell message to the recipient with an animated Minion dropping a mic then block all emails from that recipient completely, with out prompting the sender to substantiate first. Higher nonetheless, there was a bug that meant the recipient may obtain that “GIF of demise” and the block, even when the sender managed to press the proper “Ship” button within the complicated new UI.
The “hilarity” that ensued included:
- A funeral residence by chance despatched a mic drop and block to a grieving household.
- A person posted on the Gmail assist discussion board, “Because of Mic Drop, I simply misplaced my job.”
Google disabled the characteristic earlier than the top of April Fools’ Day and issued an apology saying, “It appears to be like like we pranked ourselves this yr.” I’m not certain how the joke was on Google, a lot because the folks whose livelihoods and relationships had been destroyed.
Keep in mind after I stated within the intro that April Fools’ is a distraction from how the joke is on us for believing that the online is what it appears? This Google prank was a reminder that when you consider an promoting firm masquerading as a search firm has the judgment and ethics to prioritize your pursuits, after they hoard your private information and don’t truly care if you will discover something, the true mic drop second is if you understand that your profession and relationships are an information level in Google’s subsequent A/B take a look at.
Prank UI/UX analysis articles
The funniest a part of these April Fools’ UI/UX recommendation articles is that they’re revealed by a severe, high-profile consultancy and analysis group, so the authors work arduous to make it apparent these are April Fools’ hoaxes. In every article, “APRIL FOOLS” is within the title in ALL CAPS. And within the first paragraph of the newer hoax articles: “This text was revealed as an April Idiot’s hoax and doesn’t comprise actual suggestions.” I wish to think about the advertising and marketing division thought this was an important thought, after which the authors of the articles tried their finest to not make fools of themselves. I seen the group stopped posting hoax content material after 2022.
Sidenote: Academic sources folks depend on as a supply is probably not one of the best place for prank posts. It jogs my memory of this peer-reviewed radiology web site that on April Fools ‘ Day 2015 posted a hoax X-ray picture beneath the title “Ectopia cordis interna – Tin(Man) syndrome.” Over time, medical professionals circulated the picture unaware it was a hoax, after which, in 2025, six medical journal case research involving the made-up situation needed to be retracted.
Really, the hoax UI/UX articles are instructional, in a UI antipatterns type of means, resembling “Customers Love Change: Combatting a UX Fantasy,” which advocates redesigning the UI as typically as doable for the heck of it — besides I can’t assist however really feel JIRA took that recommendation actually. The “Canine UX” article teaches concepts of person personas and design in a enjoyable means. And “The Consumer Expertise of Public Bogs” reads as if George Costanza from Seinfeld turned his bathroom obsession right into a lesson in usability.
DigitalOcean buys codepen.io
Common readers of CSS-Methods know that the founder, Chris Coyier, actually did determine in 2022 to promote the web site to our present stewards, DigitalOcean, in order that he may concentrate on his different tasks, resembling CodePen. Subsequently, the announcement on CodePen that DigitalOcean was additionally shopping for that web site appeared maddeningly believable. The extent of element within the hoax announcement elevated verisimilitude. As an illustration, the declare that customers may use customized domains on CodePen without spending a dime, so long as the area was DigitalOcean-hosted. In truth, the one signal it was a prank is that no person wherever introduced something like this, except you rely me posting it immediately on a DigitalOcean-owned web site.
Glad April Fools’ Day, everybody!
