Place it as a sudden cutaway in the middle of a montage, then follow it with Trololo Song to keep the absurd run going before returning to the main joke.

This short clip repeats my roflcopter goes soi soi soi in a flat robotic text-to-speech voice, stretching the nonsense phrase until it sounds ridiculous. It feels chaotic and nostalgic, like a joke from a forum thread that still lands because it makes no sense. The phrase comes from an early 2000s internet meme about a fictional ROFL copter, often voiced like Microsoft Sam and shared in forum and Flash-era comedy.
