Slip

A boy is standing on the edge of a cliff, and his friend runs off toward the woods shouting, "Mom, Dad, come here! You gotta see this! This is so cool—" The cliff edge the boy is standing on then gives way, and the boy falls into the sea, screaming, "Shiiiiii-(t)" as the cliff crumbles beneath him. The PSA cuts off abruptly at this point, lasting only nine seconds in total.
