Place it at the very start of your edit, right before the plan falls apart, so the announcement frames everything that follows. Follow it with WhatsApp Message Sound when the replies start arriving, keeping the chat-style back-and-forth at the centre of the joke.
Over dit geluid
This is a short Russian voice clip, about five seconds long, in which a voice calmly says he has a plan, in the style of a casual voice message. The assured, matter-of-fact delivery makes the announcement feel funny and slightly tense, because it promises a clever solution while hinting at chaos ahead. It works best as a setup for a reckless idea, turning simple overconfidence into the joke itself.
