Place it after your setup line and before the visual payoff, then follow it with the Otkroi Glazki button for a second Russian meme hit, or an Auughhh reaction to close the joke cleanly.
このサウンドについて
This is an 18-second Russian meme clip centred on the name Viktor Korneplod, spoken as a drawn-out, deadpan name drop rather than a normal introduction. It feels absurd and oddly grand, like a minor character is being announced as someone hugely important, which makes the moment land as silly and memorable.
