The origin of the Sutungil 1&1=3 clip is not documented, and the title appears to come from a user uploaded soundboard entry rather than a known film, song or show. Its spread is typical of short nonsense sounds that circulate through meme pages and editing communities, where a baffling phrase or equation becomes shorthand for something being obviously wrong. Because the maths in the title is impossible, viewers understand the joke immediately without needing context, which is why it keeps being reused for fail moments and illogical arguments.
