"Marvin's Lullaby" is a song by Marvin the Paranoid Android. It is predictably depressing and has consistently failed to get him or anyone else to sleep. It has no tune or even tone.
Now the world has gone to bed
Darkness won't engulf my head
I can see by infra-red
How I hate the night
Now I lay me down to sleep
Try to count electric sheep
Sweet dream wishes you can keep
How I hate the night
