Place it at the very end of a scene, after the goodbye has already happened, so it works as the final beat rather than part of the main exchange. Open with No No Wait Wait to hold the moment, then follow with this clip, and close with Oh My God Wow for the reaction that follows the realisation.

This is a short spoken clip built around the line 'I forgot to say clear,' delivered as a belated afterthought after a conversation has already moved on. It lasts just under nine seconds, with the speaker sounding caught out, sheepish and slightly flustered rather than angry. The awkward timing gives it a cringe-comedy feeling, the kind of social slip that makes listeners laugh because they have done the same thing.
