Two tall trees are growing in the woods.

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 on the sapling.

One of the tall trees 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."
