The rant comes from Portal 2, released by Valve in 2011, and is heard in pre-recorded messages from Cave Johnson, founder of Aperture Science and voiced by J. K. Simmons. Intended as backstory and dark comedy between test chambers, the speech became the character's most quoted moment. Clips and remixes spread widely on YouTube and gaming forums in the years after release, and the full version is still shared when players want the complete build-up rather than just the combustible lemons line.
