Two tall trees, a birch and a beech, are growing in the woods.
A small tree begins to grow between them.
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 a son of a beech nor a son of a birch. It is, however, the best piece of ash have ever put my pecker in!
