Impossible

Impossible for a plain yellow pumpkin to become a golden carriage.
Impossible for a plain country bumpkin and a prince to join in marriage.
And four white mice will never be four white horses.
Such fol-de-rol and fiddle dee of course is
Impossible!
But the world is full of zanies and fools
Who don't believe in sensible rules
And won't believe what sensible people say
And because these daft and dewey eyed dopes
Keep building up impossible hopes impossible
Things are happening every day!
