Clean Joke about Trees...but some innuendos.. Joke #4

[Stuart G]

>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 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. It is, however, the best piece of
>ash I have ever put my pecker in."
