Place it at the end of a failed-plan sequence, after Sudden Suspense and before Nelson's Ha-Ha!, so the failure lands first and the laugh follows it. Keep Oh My God Wow for the first reveal, so this clip can close the moment instead of competing with it.

This is a very short Italian voice clip, lasting about one and a half seconds, built around the phrase “moriremo tutti,” meaning “we will all die.” It feels darkly funny and dramatically resigned, turning an everyday setback into a moment of shared exaggeration. It suits the point when a plan has clearly failed and everyone can see what is coming next.
