Place it as the punchline after a setup showing someone taking charge, then follow it with a flat reaction sound to close the scene. Open with a knowing narration moment before the minister speaks, so the audience expects trouble and the line lands as the payoff.
About this sound
This is a short French line delivered by Louis de Funès in a minister's voice, lasting just under four seconds, with his rapid, clipped delivery and rising indignation doing all the work. It feels pompous and exasperated, like a small official suddenly losing patience in the middle of a grand speech. The line comes from his collection of cult replies, where his best-known comic outbursts are gathered together.
