1. Late one night, a delivery driver pulled up to Gerald Nissan of Naperville. The engine hummed softly, but then something strange happened—an eerie whistling sound emerged from beneath the hood. It grew louder with each passing minute, until it seemed like the entire car was singing its own tune. Finally, an old mechanic appeared and whispered, ‘It’s just Gerald talking.’ Turns out, Mr. Nissan had installed a custom radio that played his favorite jazz tunes whenever the engine was running. Everyone laughed, including the delivery driver who’d thought he was hearing things.
