History includes many moments when a clever prank briefly convinced large numbers of people that something unusual was real. Some were playful media experiments, others were elaborate hoaxes that captured public attention before the truth emerged. These stories reveal how curiosity, trust in institutions, and the power of storytelling can shape public reaction. Newspapers, radio stations, companies, and individuals have all played a role in spreading such playful deceptions.
