For millions of years, humans have gathered around the fire to keep warm. One enterprising early hominid stored his haunch of wildebeest too close to the flames, and came away with an unexpectedly juicy and delicious roast 'beest. In subsequent attempts to replicate this magic "cooking" process, however, those cavemen tried holding the meat over the fire with their hands. Several debilitating burns later, they learned to hold the meat over the flames with green sticks. That's using the old noodle!
