Put this clip at the exact moment a plan gets approved in your edit, right after the proposal finishes. Follow it with the Windows XP error sound if the plan immediately falls apart, or save that pairing for the reveal instead of stacking reactions on top.

This is a very short voice clip of a character saying OK, lasting just over a second, in a clear cartoon delivery. It feels dry and agreeably unbothered, like a calm yes to something that should probably be a much bigger deal. It comes from the animated television series Phineas and Ferb.
