"Where Have All The Vampires Gone?"

University of Central Florida physics professor Costas Efthimiou has employed elementary mathematics to lampoon cliche vampire folklore as portrayed in popular literature and Hollywood. According to the prof, if - starting in the year 1600 - the first vampire sunk its fangs into one human per month, and that human subsequently metamorphosed into a vampire and went on to feast on another human, the entire human population would be eradicated in under two and a half years.
Well I have a different theory which demonstrates how unbeknownst to the majority of the populace, humans and vampires currently co-exist in perfect har... well a close approximation of a harmony of sorts.

According to European, Chinese and Indian legend, vampires suffer from obsessive compulsive disorder which manifests in the insuppressible impulse to count particles of grain, sand, sawdust, rice, poppy seeds and a variety of other multitudinous identical items. To keep the bloodsuckers occupied and out of mischief should they rise from their coffins to feed, people would scatter such pacifiers throughout graveyards. They'd be so engrossed in the task of gathering them all up that before they could shriek "bright light, bright light!" the sun would begin to ascend in the sky forcing them to seek shelter until the following night where the process would be repeated Groundhog Day stylee.
This technique is effective in warding off achluophobic vampires, but not so much against the newer breed of vampire that have evolved to withstand sunlight and walk shoulder to shoulder with their unwitting victims.

Keeping these blighters in check is one of the few things we have the reptilian humanoid Illuminati (or Global Elite) to thank for. You see, these extraterrestrial prison warders - otherwise known as the Babylonian Brotherhood - from the constellation Draco compete with the daylight vampires for human blood (the hybrids sired through cross-breeding with humans consume it to transform themselves from reptiles to hominids, duh!) and so it is in their interests to assure the survival of the species.

To achieve this end the Illuminati have been remotely controlling vampires through the use of advanced brainwashing neurotechnology. With their penchant for frenzied bean-counting and parasitic jugular-mauling in mind they have been coercing the pliable vampires to sublimate their urges with (arguably) less destructive occupations. Hence we have swathes of apparently human creatures hell-bent on becoming traffic wardens, chancellors (of the exchequer), tax inspectors and inland revenue administrators.

To wrap up, we are artificially being kept alive today by the very existence of penny-pinching, Neo-Nazi, public servant vultures (aka sedated vampires). It's obvious really if you think about it. I dare anyone to propose a flaw in the theory.
