Place this clip right after the wrong calculator result appears, then follow it with a funny ha ha laugh to close the joke. For a fake quiz setup, put a game show correct answer first, even though the maths is completely wrong, and let this clip carry the reaction.
About this sound
This roughly fifteen second clip pairs the Einstein calculator meme with the typed number 67, turning a simple calculator entry into a full meltdown. It feels absurd, frantic and deliberately over the top, as if a tiny maths input has broken serious science, which is why listeners treat it as pure brainrot comedy rather than a straight reaction.
