The Illuminati confirmed joke grew out of internet conspiracy humour, where creators pointed to triangles, pyramids, and eye-like shapes in logos, photos, and everyday objects as mock proof of a secret society. Short videos built the gag around a dramatic reveal, letting an ordinary detail suddenly look suspicious, and the format spread easily because anyone could spot a triangle and add the same punchline. It is still used today because the joke needs no explanation: one familiar sting turns a coincidence into a playful conspiracy reveal.
