Place it at the very start of a scene as the greeting, then cut to the reaction with Anime Ahh before closing the joke with Awkward Moment when the room goes quiet.

This is a short voice clip of about 2.6 seconds in which a voice greets listeners with the words 'Hey kids.' The greeting feels playful and a little sinister at the same time, like a joke delivered by someone who knows more than they are letting on. It comes from Team Four Star's Hellsing Ultimate Abridged.
