Place it as the payoff at the end of a short skit, after a game show buzzer signals a wrong answer and before a meme sting closes the scene, so it becomes the unexpected reward for watching to the end.
O tym dźwięku
This is a wordless vocal performance, about ten seconds of cheerful la-la-la style singing over a bright orchestral backing, with a rising, playful melody and no lyrics at all. It feels absurdly upbeat and charmingly awkward, like a confident performance that makes no sense and still works. It comes from Soviet singer Eduard Khil's 1976 television performance of 'I Am Very Glad, as I'm Finally Returning Back Home'.
