Trees

It is hard to find a joke today without a dirty word or two in it, but 
here is one:

Two tall trees, a birch and a beech, are growing in the woods.

A small tree begins to grow between them, and 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 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 I have ever put my pecker in."
