Stuffing Rabbits in your Vagina

In the quiet town of Godalming England, in the year 1726, an event completely unique in the history of medicine was taking place.

From Wikipedia:

Mary Tofts was twenty-five years old and married at the time, and despite a miscarriage in August had still seemed pregnant. She went into apparent labor and the Guildford male-midwife John Howard arrived to assist. Howard reported that Mary told him she and a friend had been weeding in a field when they saw two rabbits and chased them: the escape of the rabbits created "such a longing" in Mary that she miscarried and from then on could think of nothing but rabbits. Soon, Howard recorded, she began producing parts of animals: a rabbit's liver, the legs of a cat, and, in a single day, nine baby rabbits.[1] Howard sent letters to some of England's greatest doctors and scientists asking for help investigating the situation, and among those who came to his assistance were Nathaniel St. Andre, surgeon-anatomist to King George I, and Sir Richard Manningham, the most famous obstetrician in London. Tofts gave birth to several more dead rabbits in their presence.

Tofts claimed that during pregnancy she had an intense craving for roast rabbit, that she tried to catch rabbits in the garden, that she had admired them in the village market, and that she had dreamed about rabbits. Based on this testimony, the doctors explained the births as a result of "maternal impressions", contending that a pregnant woman's experiences could be imprinted directly on the fetus at conception and cause birth defects.

Sir Richard Manningham eventually exposed the birthings as a hoax after a porter admitted smuggling a rabbit into Mary's chamber. Tofts was forced to admit on 7 December 1726 that she had manually inserted dead rabbits into her vagina and then allowed them to be removed as if she were giving birth.

Unprecedented in the history of medicine, and remains elusive to this day, but what truly transpired that year in England is a phenomenon as old as human society.
