Place this clip at the reveal of a seven in an edit, then follow it with Nico Nico Nii before the cut. If the joke needs a bigger reaction, close with Funny Ha Ha Laugh instead of stacking another chant.

This roughly 14-second clip centres on the repeated vocal phrase 'sieben sieben ay lyu lyu', delivered as a short musical hook with a chant-like rhythm. Its playful, bouncy repetition makes it feel light and a little absurd, the kind of earworm that lands best when it catches a listener off guard.
