Place it at the end of a clip showing a keyboard typo, then follow it with a reaction sound to let the joke land, and keep it away from dialogue so the random moment stays the focus.
O tym dźwięku
This is a short sound effect lasting about 2.8 seconds, listed under the name 123ertyujk with no performer, description or source attached. It plays as one brief, self-contained clip, so it works best as a quick interruption rather than a longer moment. The feeling is one of sudden curiosity, because nothing in its name explains what is coming next, and it leaves the listener wondering what it was.
