Place it in the middle of an edit, just after the question or mistake that causes the confusion, then follow it with SpongeBob Fail for the reaction shot. For a different gag, start with a classic fart and let this clip carry the punchline instead.

This is a six-second fart noise stretched in slow motion, so the crude blast drags out into a long, wobbling groan instead of a quick pop. It feels deliberately dumb and awkward, like a thought grinding to a halt in public, and it makes a blank look or a failed answer seem even more embarrassing.
