GOO-ey Candy

In the late 1950s in Munich, Germany medical investigators undertook a curious study.
Sexual body fluids were taken from male and female volunteers, sterilized, and incorporated into candies. These candies were then distributed at random to young adults. The candies were distributed by both the original body fluid donors and unknowing volunteers.
The investigators discovered that within a short time, a large number of these candy-eaters found one another and hooked up. These randy candy munchers often had to go a fair distance to find (unbeknownst to them) another person who'd eaten the candy. Of course, they also had no idea that the person they were suddenly so attracted to had eaten the candy too.
When later debriefed by the investigators, the participants simply could not explain what led them to behave as they did.
There's no mention of whether or not they tried to kick the asses of the medical investigators after being informed of what they'd been eating.
