One of the topics I cover in Elephants on Acid is experiments with animals who exhibit mating behavior toward "biologically inappropriate objects." For instance, during the 1950s, Martin Schein and Edgar Hale of the University of Pennsylvania conducted a series of experiments to determine what objects would elicit a sexual response from male turkeys. They discovered that all you have to do is show a male turkey a severed turkey head on a stick, and the dim-witted birds would invariably try to mate with it. And researchers at Walter Reed Army Medical Center created a "hypersexual cat" who attempted to mate with "a small and rather friendly dog," an old hen, and a rhesus monkey. (I have photographic documentation of these experiments in the book.)
These following stories don't have anything to do with hoaxes, but they did remind me of the experiments in my book:
Lusty Camel Kills Woman
An Australian woman was killed by a pet camel she had received for her 60th birthday when the camel knocked her to the ground, lay on top of her, and began trying to mate with her. Earlier the same camel had almost killed the family's pet goat by trying to have sex with it. I'd say they've got a problem with that camel.
Man Arrested For Sex Acts With Traffic Signs
Proving that no matter how odd the mating behavior of animals is, the behavior of humans is always stranger, police arrested a Sioux Falls man who had amassed a large collection of videos of himself "engaged in masturbation and sex acts with traffic signs near his home."
