The poem
Once upon a time there was a mistake So silly so small That no one would even have noticed it
It couldn't bear To see itself to hear of itself
It invented all manner of things Just to prove that it didn't really exist
It invented space To put its proofs in And time to keep its proofs And the world to see its proofs
All it invented Was not so silly Nor so small But was of course mistaken
Could it have been otherwise
