© National Geographic Society 503 Robert F. Sisson and Donald McBain, National Geographic Staff "It's for You, Doc... and Don't Forget to Order Some Bananas" Sumatran orangutans, posing here as the author's telephone monitors, are born clowns. They can be taught to smoke cigarettes, drive nails with a hammer, and ride bicycles. Frisky and goblinlike in youth, Pongo pygmaeus grows sluggish and sober with age. At least one circus specimen has been billed as "The Wild Man of Borneo."
