Cartoon Network's late-night block Adult Swim has held a number of their own April Fools' programming stunts, such as promoting a television premiere of "Aqua Teen Hunger Force Colon Movie Film for Theaters" before its theatrical release (but only showing it in a comically-small picture-in-picture display over regularly-scheduled programming instead), airings of the Tommy Wiseau film "The Room", an airing of "The Room" that segued into a one-off revival of Cartoon Network's former anime block Toonami (which was later re-launched within Adult Swim), and an airing of Toonami with all programming in Japanese audio with subtitles rather than an English dub. The stunts have sometimes included unannounced previews and premieres of new and existing series, such as additional episodes of "Perfect Hair Forever" after its supposed series finale, the third season premiere of "Rick and Morty", bumpers featuring various previews hosted by rapper Post Malone in 2020, and during the aforementioned Toonami in Japanese stunt, an unannounced world premiere of the first episode of "FLCL"s third season "FLCL Alternative" before its second season "Progressive" had even premiered in the U.S. yet.
