Erbert & Gerbert traveled back to prehistoric northern Spain where they met a young cave boy. He didn’t have a name, so the boys called him Bornk because any time a prowling animal came near his cave, he BOORRRRRNNK-ed them on the head with his club. Because of Bornk’s brutish behavior, grunty language and shabby animal skin attire, the boys felt ever-so-slightly superior to their primitive pal. Until one day, when Bornk lit a torch and took them deep into the belly of a cave. He took some grease out of his pouch and smeared it on the wall. Then, he blew a powdered concoction through an animal bone onto the grease. When he finished, the boys were amazed to see the painting of a bison staring back at them in the flickering torchlight. It was a masterpiece. And it taught the boys a valuable lesson: Never judge a Bornk by his cover.
