Phil Shone, a New Zealand deejay for radio station 1ZB, announced to his listeners that a mile-wide wasp swarm was headed towards Auckland. He urged his listeners to take a variety of steps to protect themselves and their homes from the winged menace. For instance, he suggested that they wear their socks over their trousers when they left for work, and that they leave honey-smeared traps outside their doors. Hundreds of people dutifully heeded his advice, until he finally admitted that it had all been a joke.
The New Zealand Broadcasting Service was not amused by Shone's prank. Its director, Professor James Shelley, denounced the hoax on the grounds that it undermined the rules of proper broadcasting. From then on, a memo was sent out each year before April Fool's Day reminding New Zealand radio stations of their obligation to report the truth, and nothing but the truth.
