My universe is my eyes and my ears. Anything else is hearsay. - Douglas Adams

He has personality problems beyond the dreams of analysts.

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,
How I hate the night.
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,
How I hate the night.
