Place it as the final beat in a short edit, right after the setup scene and before any reaction shot. Follow it with the Run Vine sound for a second sudden escalation, or open with the Bruh sound to set up a reaction before the train moment arrives.
About this sound
This seven-second clip opens with a flat, deadpan voice saying “I like trains,” then cuts straight into a noisy train gag. The contrast feels funny and jarring, turning a plain statement into a sudden, darkly absurd interruption. It comes from TomSka’s asdfmovie cartoons, where the line became one of the series’ most quoted recurring bits.
