+This planet has -- or rather had -- a problem, which was this: most
+of the people living on it were unhappy for pretty much of the time.
+Many solutions were suggested for this problem, but most of these
+were largely concerned with the movements of small green pieces of
+paper, which is odd because on the whole it wasn't the small green
+pieces of paper that were unhappy.
