"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.'"
