The clip comes from Steins;Gate, the science fiction series about Okabe Rintaro, a self-styled mad scientist whose microwave time experiments turn bananas into green gel versions. That running experiment made bananas closely associated with Okabe and the Future Gadget Laboratory, so even a single mention became an easy shorthand for fans. As short anime lines circulated on soundboards and in edits, this isolated banana delivery survived on its own, reused whenever a video needed a nerdy, pseudo-scientific punchline or a quick reference that other Steins;Gate viewers would catch immediately.
