A Birch And A Beech In A Forest

saw a sapling a ways off, and the birch says " I bet that's a son of a Birch" and the Beech says "No, that's a son of a Beech" They argue back and forth then decide to call over a woodpecker. " Go over to that sapling and and find out whether it's a Birch or a Beech tree. So the woodpecker flies over, and taps the sapling a few times with its beak and comes back. " So, which is it?" the Beech asks. "I'm not sure, but that's the best piece of Ash I've ever had my pecker in"
