"Man had always assumed that he was more intelligent than dolphins because he had achieved so much... the wheel, New York, wars, and so on, whilst all the dolphins had ever done was muck about in the water having a good time. But conversely the dolphins believed themselves to be more intelligent than man for precisely the same reasons."
Douglas Adams, The Hitchhiker's Guide to the Galaxy
"A Mexican newspaper reports that bored Royal Air Force pilots stationed on the Falkland Islands have devised what they consider a marvelous new game. Noting that the local penguins are fascinated by airplanes, the pilots search out a beach where the birds are gathered and fly slowly along it at the water's edge. Perhaps ten thousand penguins turn their heads in unison watching the planes go by, and when the pilots turn around and fly back, the birds turn their heads in the opposite direction, like spectators at a slow-motion tennis match. Then, the paper reports, "The pilots fly out to sea and directly to the penguin colony and overfly it. Heads go up, up, up, and ten thousand penguins fall over gently onto their backs."
