Place it at the end of a sibling scene, just after the exit, then follow it with Eww Brother Eww for a second reaction before Oh My God Wow ends the scene.

This is an 11-second voice clip centered on the phrase 'Oh brother is gone,' spoken as a reaction to someone finally leaving. It carries a tired, relieved feeling, part exasperation and part quiet satisfaction, as if the speaker has been waiting for this moment and can finally enjoy the silence that follows.
