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.
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. It is, however, the best piece of ash I have ever put my pecker
in."
