Place it right after the visible failure in your edit, then follow it with SpongeBob Sad Song to stretch the joke into a longer gag. For a sharper contrast, open with a confident moment first, then cut to this line as the payoff.

This two-second voice clip has Wallflower Blush delivering the line 'Nothing I do matters' in a quiet, defeated tone. It feels flat, weary and painfully relatable, like giving up after trying hard and getting nowhere. The resigned delivery makes the sadness land as gentle, self-deprecating humour rather than a dramatic outburst.
