Put it immediately after the impact in a fail edit, following a sudden suspense build-up, then follow it with the sad violin for mock sympathy. That order gives the mishap a comic payoff, and works best when the fall itself stays visible on screen.
O tym dźwięku
This short clip captures the Black Knight insisting his injury is only a flesh wound, delivered in a stubborn, matter-of-fact British voice over about six seconds. It feels defiantly funny, turning a serious setback into a joke by refusing to admit defeat. The line comes from Monty Python and the Holy Grail, spoken after the knight loses an arm in a sword fight.
