Place it near the end of a short edit, after the setup has settled, and let it close the joke. Follow it with the Bruh sound for a deadpan reaction, or lead into it with Goofy Ahh Sounds to build the chaos first.

This short clip pairs two loud, exaggerated young voices in quick succession: a blunt, mock-angry shout aimed at a potato, then a cheerful sing-song declaration about liking trains. The sudden switch from fake aggression to innocent enthusiasm feels absurd and playful, like a random outburst that needs no setup. The trains line comes from the asdfmovie series of short animated sketches.
