Put it near the end of a scene as the closing interruption, then follow it with Law & Order Dun Dun to underline the fake-serious turn, or open with DJ Airhorn before it for a louder contrast in the edit.
About this sound
This is a brief Japanese spoken line, lasting about five seconds, delivered in a polished, formal announcer voice that begins “AC Japan wa kono katsudo wo...” and stops before the slogan finishes. The unfinished delivery feels awkward, abrupt and oddly funny, like a serious broadcast interrupted mid-sentence. It comes from AC Japan public service television ads.
