One time, Erbert and Gerbert traveled way, way back 5,000 years to ancient Egypt where they met Narmer, the official duster of the Great Pyramid at Giza. Narmer was in charge of polishing its many treasures, so he took the boys down into the Pharaoh Cheops tomb to see them. There they saw some stupendous sights—everything from statues carved from pure gold to jewels of every color imaginable. When they emerged from the tomb, Comet Morehouse was up to his old fireballing tricks and chased them up to the top of the pyramid. But Narmer knew of a secret entrance in the back, so they all slid down to safety. Unfortunately, the damage to the pyramid was done. What was once a gleaming limestone surface that made the pyramid glow from hundreds of miles away was gone, except for the very tip. And that’s why, to this day, the pyramids have their original coating only at the very top.
