Having solved all the major mathematical, physical, chemical, biological, sociological, philosophical, etymological, meteorological and psychological problems of the Universe except for his own, three times over, [Marvin] was severely stuck for something to do, and had taken up composing short dolorous ditties of no tone, or indeed tune. The latest one was a lullaby.Marvin droned,Now the world has gone to bed,Darkness won't engulf my head,I can see in infrared,He paused to gather the artistic and emotional strength to tackle the next verse.Now I lay me down to sleep,Try to count electric sheep,Sweet dream wishes you can keep
~ Douglas Adams
