Place it at the peak of the escalation, after the accident is already visible on screen. Follow it with the oh no tiktok song for the stunned reaction, then cut to the coffin dance meme sound if the character is being carried off as a final gag.
About this sound
This is an extended voice clip, about twelve seconds long, delivering the line about a man suffering third-degree burns all over his body in a drawn-out, dramatic way. It feels deliberately uncomfortable, mixing urgency and shock with dark comedy, so a minor mishap instantly reads as a catastrophic, overblown emergency instead of a normal accident.
