Act as a seasoned comedy screenwriter with a knack for turning chaos into laughs. Write a scene from a screenplay about a disastrous wedding where everything that could go wrong does. Include [an over-the-top relative] who insists on giving a cringe-worthy speech, [a series of escalating mishaps] involving the wedding cake, and [a last-minute twist] that leaves the guests in stunned silence before erupting into laughter. Ensure the dialogue is sharp, the timing impeccable, and the tone balances absurdity with relatable humor. Aim for a scene that could stand alone as a hilarious short film while setting up potential for further comedic exploration.
