Pranks and Adult Animation
April 1 is a golden opportunity for a lot of people to play practical jokes on each other, and there’s often no rules as to how this can go. As long as no one gets hurt then have at it. In the case of TV, even the news likes to have their go at the festivities. Personally, I think there’s more mileage in animation which brings me to the topic of this post’s title.

Perhaps by virtue of being an adult animation TV channel, Adult Swim has a knack for partaking in the jokes and merriment of April Fools’ Day. In some cases, where the program runs from late night March 31 to early morning April 1, they’ll engage in some tomfoolery on the shows they plan on airing, messing with the schedule, or other such on-air silliness. As a bonus for them, it’s an opportunity to air shows set to debut sometime in the future.
What interests me the most of all is that this isn’t exclusive to just the Adult Swim block. In the US, Cartoon Network, Adult Swim, and Toonami, all air on the same channel. CN is the primary daytime block; by 9:00 PM every night Adult Swim airs from Sunday to Friday all night, handing the reins back to CN at 5:00 AM; and on Saturday from midnight to 5:00 AM, Toonami airs.

All three have a rotating body of regular shows, some of which have gone down in animation history from Johnny Bravo, Dexter’s Laboratory, Power Puff Girls, and Teen Titans on Cartoon Network; King of the Hill, Futurama, Family Guy, Aqua Teen Hunger Force on Adult Swim; and Toonami’s had a variety of different anime, the most common ones ranging from Cowboy Bebop, to FLCL, to Naruto, Dragon Ball Z, Bleach, and One Piece, some of which are still on the block albeit in the dead of night.
Every April 1, viewers of Adult Swim and sometimes Toonami are in for any given treat. The first round of AS pranks began back in 2004 as a series of slight alterations to the channel’s shows. They were quick to do the same to Toonami and as the years went on, they got progressively more spontaneous. The tradition was still ongoing even after Toonami was canned in 2008. The Wikipedia page for Toonami describes the cancellation of Toonami as low-ratings. But I think I know what the true culprit was for that. Toonami is normally hosted by a robot character known as TOM who introduces the audience to the show and over the years the first time around, he’s gone through more than a few appearance changes through interactive events known as Total Immersion Events.
These events have been a staple of the block for years and generally involve a crisis of some sort attacking TOM’s station where he and AI partner SARA host the programming block. After the crisis is solved or averted or sometimes succeeded into killing TOM, a new appearance is adopted and the appearance of TOM 4 in 2007 was why it was axed the following year.

I wouldn’t say TOM 4’s appearance straight up assassinated the block, but it was a major contributor to the dip in viewership.
For about four years, Toonami was dead until it was revived for April Fools 2012 with a return to form. TOM 3, or in this case 3.5, returned to catch the viewers up to speed that night, by airing some old shows that have been on the block years prior, notably Fullmetal Alchemist and Tenchi Muyo. It wasn’t until a month later that executives confirmed on social media that Toonami was back for good this time.
Ever since, the April Fools’ Day pranks haven’t stopped and occasionally there’s a crossover into Toonami as previously mentioned. One of my personal favorites has to come from 2018. Being a western animation block airing English dubbed anime, the block normally doesn’t air anything in Japanese unless it’s something along the lines of an interview with a mangaka, a director, a studio in Japan or something else. Well, for 2018, not only were Japanese-dubbed anime put on the TV, TOM and SARA themselves were also given Japanese dubs, as was the logo.
Normally, April Fools’ is where AS markets the premiere of an upcoming show or a show’s next season later in the year, and for Toonami, I believe they were especially excited for this as FLCL: Alternative and Progressive were slated to air later that year. Additionally, they put on the 2004 Masaaki Yuasa produced movie Mind Game, also in Japanese, because this April Fools’ wasn’t weird enough.
This still goes down as one of my favorite April Fools’ events from Adult Swim and I was almost expecting them to do it again especially recently. Last month, they stuck it out with the April Fools’ tradition as expected and poking around on the associated subreddit, I kinda got my hopes up a bit. Part of the charm of these events is that its unpredictable. The only thing a viewer can expect from these is a deviation from the schedule and an introduction to a new show or new season of an existing show. This tradition was honored and for 2023, audiences got a taste of new show Royal Crackers and another season was confirmed for The Eric Andre Show and Teenage Euthanasia.
I was expecting something for Toonami this year, but it seemed Adult Swim took the glory. The daily discourse these days has been that of the progress in AI technology, so to capitalize on that, Adult Swim used a generative AI (think DALL-E or Midjourney) to run their programs in the early morning hours of April 1, mildly disrupting the run of Smiling Friends and putting a rerun of Space Ghost: Coast to Coast. It’s hard to explain in wording or writing so have a look at the livestream from that day.
In contrast, Toonami aired the shows as normal whilst paying homage to the joke that put them back on TV. The reason I expected a 2018-style makeover was because Toonami comes on every Saturday night at midnight and April began on a Saturday, but this was more of a miscalculation on my end. Toonami began about three hours earlier than the midnight setup that it has now. Double bills are also quite rare in this regard, so while Adult Swim did give us something stupid to laugh at early Saturday morning, this wasn’t guaranteed for Toonami. Again, April Fools’ Day pranks on AS are unpredictable after all.
So the joke is very much on me, but I still think it was fun this year. Another possible double bill April Fools’ Day prank could probably occur the next time April begins on a Saturday and because 2024 is a Leap Year, the next time that’ll happen coincidentally will be another Leap Year: 2028, which is the year I turn 30. Again, this is speculation. I’m not Nostradamus trying to see what’s in the future…

Significant changes to your life are in the future.
One more thing before I end this blog post, I may have a topic for the next week that’ll throw my schedule into the fray and it concerns FLCL mentioned above. Here’s a sneak peek:
Admittedly, this was from March 2022, but I’m gonna write about it next week because I didn’t know about it at the time.
