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 it can`t tell. Just then a woodpecker lands on the sapling.The birch says: "Woodpecker , you are a tree expert. Is that a son of a beech or a son of a birch ?" The woodpecker takes a small taste of the sapling and replies: "It is neither a son of a beech or a son of a birch. It is , however , the best piece of ash I have ever put my pecker in !"
