The world is full of goods trains
The passengers are cows
And milk and butter.
And cheese and lovely marmelade
And bulls and horses,
And cocks and hens.
The cow is mother to the milk,
And grandma both to cheese and butter.
The cheese is cousin to the marmelade.
The horse is cousin to the cock
The hen lays eggs.
The egg is cousin to the cheese and butter,
The son and daughter of the milk.
Isn't it strange?
