Place it as the final beat of an edit, after the last failed attempt or goodbye, so the closing moment carries the joke. Follow it with the Directed by Robert B. Weide sting for a slower comic fade, or lead into it with the Ba Dum Tss drum sting when the ending needs a quicker gag first.
About this sound
This 19-second clip carries the chorus of Elektryczne Gitary's Polish rock song, with a male voice singing the closing line over bright, upbeat guitar pop. It feels weary yet amused, like a shrug at a finished chapter, turning a goodbye into something light rather than sad. The song dates from the early 1990s and its refrain has since become a familiar Polish way of saying something is over.
