Five decades after the discovery of fire, a certain caveman named Algo began going from cave to cave, telling everyone that the heat from their campfires was causing a dangerous rise in the temperature. At first the other cave dwellers ignored Algo, thinking perhaps his wooly mammoth drawers were too tight, but they soon began to warm to his warming theory. For you see, Algo had once been vice chairman of the mountain in which their caves were pocked. Soon, Algo was looked upon by some of the more mentally challenged cave dwellers as a prophet of sorts. They bought into his warming theory, declaring that it made perfect sense that man-made fires all over the mountside would warm their rock.
Algo warned of total destruction unless something was done to offset the heat the fires were emmitting. Algo set up an exchange where cave dwellers who built more than their fair share of fires could purchase a heat credit. A credit cost one stick of firewood. Since it was Algo's idea, the exchange belonged to him. Soon, all the cave dwellers were giving firewood to Algo in order to offset the damage they were doing by building fires. Algo put his extra firewood to good use by keeping his cave warm day and night. He had so much firewood that he began to light sticks of it and place them outside his cave at night -- becoming the first caveman in history to have outdoor lighting.
But not all cave dwellers believed Algo's theory. They questioned his large fires and outdoor lighting and wondered aloud why a caveman who believed fire was destroying their mountain would keep his fires going all the time. Algo countered by taunting them. He called them stupid and forbid his followers from engaging them in debate.
Then the ice age began. As the ice covered the mountainside, Algo declared that his theory had been proven true. The mountain was freezing, just like he had said it would. But the non-believers reminded everyone that Algo had predicted the mountain would become so hot they would all have to leave. Some of Algo's followers pulled their heads from his wooly garment and began to see the truth. Algo was a fraud.
Some -- the dumbest of the dumb -- refused to believe that Algo could be wrong. It seemed perfectly reasonable to them that the heat from their fires had caused the moutain to be covered with ice and snow. The rest of the cavemen laughed at them and called them "Algoites". But that was hard to pronounce. Eventually, someone combined the words "Algo" and "follower" and coined the term that would mark Algo's followers forever -- "Algoer".
As the ice became thicker, the Algoers extinguished their fires in a vain attempt to warm their mountain. They quickly froze to death. Eventually, all the cavemen froze to death. There was a rumor that one caveman survived due to an abundance of firewood ... but that is just a rumor.
