Place it right after the mistake in your edit, following Wrong Answer Game Show to set up the fail, then follow it with Nelson's Ha-Ha! to turn the moment into a joke. Keep it as the single reaction beat between the setup and the laugh, not the main event.
Over dit geluid
A short spoken clip lasting just over a second, built around a single sharp delivery of the Spanish word for stupid. The voice is blunt and mocking, landing like a quick put-down rather than a long rant. It feels teasing and dismissive, the kind of line that makes a silly mistake feel even sillier, and it works best as a fast reaction to something obviously wrong.
