The Mad Gardener’s Song

He thought he saw a Garden-Door
That opened with a key:
He looked again, and found it was
A Double Rule of Three:
‘And all its mystery,’ he said,
‘Is clear as day to me!’

He thought he saw a Argument
That proved he was the Pope:
He looked again, and found it was
A Bar of Mottled Soap.
‘A fact so dread,’ he faintly said,
‘Extinguishes all hope!’

Lewis Carroll, The Mad Gardener’s Song
