> The birch says he cannot tell.
>
> 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. He replies,
> 'It is neither a son of a beech nor a son of a birch.
> It is, however,
> the best piece of ash I have ever put my pecker in.'
