Two tall trees, a birch, and a beech, are growing in the woods. A small
tree begins to grow between them, and the beech says to the birch,
'Is that a son of a beech or a son of a birch?
The birch says he cannot tell, but just then a woodpecker lands on the sapling.
The birch says, 'Woodpecker, you are a tree expert. Can you tell if that is a son of a beech or a son of a birch?'
The woodpecker takes a taste of the small tree and replies, 'It is
neither a son of a beech nor a son of a birch.
It is, however, the best little piece of ash I have ever poked my pecker into.'
