Place it right after the death in your edit, then follow it with a shocked reaction sound before a laugh sound closes the sequence, so the death, the reaction and the laugh land as three separate beats in order.
À propos de ce son
This four-second Italian voice clip repeats the line 'Hanno ucciso Kenny' as Kenny dies yet again in South Park. The familiar death joke feels funny and a little darkly absurd rather than sad, because the line treats a dramatic death as an everyday event. It comes from the Italian version of South Park, where Kenny's repeated deaths became a running gag.
