two trees are growing in the woods, when one day a sapling grows inbetween them.
the first tree asks the other "hey, is that a son of a birch or a son of a beech?"
the second tree replies "i dont know, but here comes a woodpecker. we can ask him."
so they say to the woodpecker "mr woodpecker, you're an expert on trees. is that a son of a birch or a son of a beech?"
the woodpecker flies down and tastes a little sap and flies back. he says "gentlemen, that is neither
a son of a birch nor a son of a beech. that is the finest piece of ash i've ever had my pecker in!"
