The Society for Indecency to Naked Animals, or SINA [pronounced "sinna"], was a satiric hoax perpetrated by comedian Alan Abel from 1959 to 1962. The group used the language and rhetoric of conservative moralists for the aim of clothing naked animals, including pets, barnyard animals, and large wildlife. An alleged debate within SINA was how large an animal had to be to require clothing. Slogans such as "Decency today means morality tomorrow" and "A nude horse is a rude horse" were offered. Actor Buck Henry played the group president, G. Clifford Prout, and Alan Abel played the group vice president.
SINA actually acquired ardent supporters, some of whom attempted to contribute a great deal of money. That aided SINA's (false) claims of gaining momentum - at one time they claimed tens of thousands of members. They also published a newsletter, in an issue of which is this anthem:
The hoax was exposed when staff on Walter Cronkite's CBS television news show recognized Buck Henry while taping an interview. Alan Abel managed to keep the newsletter going for several more years, hoaxing members who had not seen or heard of that Cronkite episode. The hoax appears in a recording of the short-lived television series One Man Show in an episode hosted by Groucho Marx.
