Place this clip just before the visual payoff in a reaction edit, then follow a failed attempt with the fail sound meme or a stunned pause using the bruh meme sound to close the sequence cleanly for viewers.
このサウンドについて
An 8-second spoken clip of a single voice stating, with calm certainty, that everybody in Uganda knows kung fu. The line is delivered flat and clear, with no music or effects behind it. It feels funny and faintly absurd, the humor coming from how seriously such a sweeping claim is presented, like a fact no one would question.
