BEECH OR BIRCH

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 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"
