Trees

Two tall trees, a beech, and a birch, are growing in the woods.
One day,a small tree begins to grow between them.
One tree says to the other: "Is that a son of a beech or a son of a birch?"
The other says he cannot tell.
Just then a woodpecker lands in the sapling.
The tall tree 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."
