Place this clip right after the visual reveal in your edit, then follow it with the eww brother eww reaction for a second beat. If you want a longer sequence, lead into it with a cartoon slip for slapstick context before the reveal lands.

This is a short voice clip lasting just over four seconds, built around the single word toenails said as a standalone reaction. It lands as gross and awkward in a funny way, the kind of blunt interjection that turns a normal moment into an instant cringe joke for listeners who get the unexpected reference.
