“Oral sex is widely used in human foreplay, but rarely documented in other animals. Fellatio has been recorded in bonobos Pan paniscus, but even then functions largely as play behaviour among juvenile males. The short-nosed fruit bat Cynopterus sphinx exhibits resource defence polygyny and one sexually active male often roosts with groups of females in tents made from leaves. Female bats often lick their mate’s penis during dorsoventral copulation. The female lowers her head to lick the shaft or the base of the male’s penis but does not lick the glans penis which has already penetrated the vagina. Males never withdrew their penis when it was licked by the mating partner. A positive relationship exists between the length of time that the female licked the male’s penis during copulation and the duration of copulation. Furthermore, mating pairs spent significantly more time in copulation if the female licked her mate’s penis than if fellatio was absent. Males also show postcopulatory genital grooming after intromission. At present, we do not know why genital licking occurs, and we present four non-mutually exclusive hypotheses that may explain the function of fellatio in C. sphinx.”

“The experience of having had intercourse with the devil has in the past been regarded as evidence that the individual is a witch. Those investigating cases of witchcraft were advised to seek the judgment of doctors, and the verdict of physicians became a test for the presence or absence of witchcraft. The woman described in this case study might well have suffered the death penalty in former times. She is unusual because of her belief that she had had intercourse with the Devil, and because the belief was shared by her religious minister. The patient also presents a diagnostic problem.”
Experimental simulation of a haunt experience and elicitation of paroxysmal electroencephalographic activity by transcerebral complex magnetic fields: induction of a synthetic “ghost”?
“To test the hypothesis that experiences of apparitional phenomena with accompanying fear can be simulated within the laboratory, a 45-yr.-old journalist and professional musician who had experienced a classic haunt four years previously was exposed to 1 microTesla, complex, transcerebral magnetic fields. Within 10 min. after exposure to a frequency-modulated pattern applied over the right hemisphere, the man reported “rushes of fear” that culminated in the experience of an apparition. Concurrent electroencephalographic measurements showed conspicuous 1-sec.-to-2-sec. paroxysmal complex spikes (15 Hz) that accompanied the reports of fear. A second magnetic field pattern, applied bilaterally through the brain, was associated with pleasant experiences. The subject concluded that the synthetic experience of the apparition was very similar to the one experienced in the natural setting. The results of this experiment suggest that controlled simulation of these pervasive phenomena within the laboratory is possible and that this experimental protocol may help discern the physical stimuli that evoke their occurrence in nature.”
“OBJECTIVE: To see if a public awareness campaign might be justified around Halloween with regard to the dangers of egg throwing… …RESULTS: 13 ocular injuries that were attributed to assault with a raw egg were reported. In all the 13 cases, the eggs had been thrown by strangers. 12 of the patients were men and the average age of the victims was 27.9 years… …CONCLUSIONS: Although most of our patients showed improvement in visual acuity, there were severe injuries, with the potential for severe ocular morbidity. We conclude that there is sufficient injury caused by this prank to warrant a public health message. At the least this practice should not be promoted by the press.”
“The following case report describes an accidental stabbing that occurred on Halloween. The unwitting victim, while preparing for a holiday charade, stabbed himself with an ornamental dagger. By placing himself in a potentially hazardous situation, the victim’s behavior entailed risk taking. The psychological implications of such risk taking are complex, and may be compared to such behaviors as russian roulette, gambling, and parasuicide.”
