Place it at the end of a gaming clip, right after the winning move, then follow it with the thief's laugh for a second villainous beat before the mission passed sting closes the edit. That order keeps the joke focused on one cheeky character moment.

This is a short clip of Waluigi's high-pitched, exaggerated cackle, lasting about 1.8 seconds and built around his smug, sneering laugh. It feels mischievous and gleefully mean-spirited, like a villain celebrating a cheap trick, and it lands as pure cartoon comedy rather than a warm chuckle.
