This is a 0.4-second clip built around the idea of phoning the United Nations, so brief that it lands as a single abrupt interruption rather than a conversation. It feels sudden and over-the-top, turning an ordinary complaint into an exaggerated appeal to the highest authority available. The brevity is the joke: it is gone before anyone can answer.
