Two tall trees are growing in the bush. One day a smaller tree begins to grow between them. One of the big trees says to the other, "Is that a son of a beech or a son of a birch." The other says that he cannot tell.

As luck would have it a cockatoo lands on the small tree and starts swinging around like a loon. The big tree yells at the cockatoo, "hey, cockatoo and you are a tree expert, is that little tree a son of a beech or a son of a birch?"

The cockatoo takes a taste of the small tree and replies, " it is neither a son of a beech or a son of a birch, that is the best piece of ash I’ve had my pecker in for a long time !"
