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 in 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. That, my friends, is the best piece of ash I have ever put my pecker in.”
