SINNA: Alan Abel's Indecency Hoax

In 1959, prankster Alan Abel initiated a hoax called The Society for Indecency to Naked Animals (SINNA), claiming their mission was to clothe animals for decency. With the slogan "A nude horse is a rude horse," Abel generated press releases and convinced people of the organization's existence. The "president," portrayed by actor Buck Henry, even appeared on Walter Cronkite's CBS news show in 1962. The ruse persisted until 1963, when Time magazine exposed it.
