Place it at the end of a prediction clip, just after the result is revealed, as the closing reaction. Open the same edit with Oh My God Wow for the surprise, then follow this clip with Nelson's Ha-Ha! as a second reaction before the edit ends.
About this sound
This short voice clip lasts just under four seconds, with a speaker declaring 'I was right all along' before breaking into a hahaha laugh. The delivery feels smug, triumphant and gleefully vindicated, turning a simple claim into a taunt aimed at doubters. It works as a quick burst of gloating humour for anyone proved correct after being doubted.
