Hiding in the tall grass of the African plains, a hungry lion stalked a grazing herd. The lion picked out an old bull, which he then attacked and killed. As the lion feasted on its prey, it would stop every once in a while and let out a mighty roar of triumph. Now it just so happened that there was a hunter nearby who heard the lion roaring so he sneaked up on it and shot the lion dead!
And the moral of this little tale is simply this: When you mouth is full of bull keep it shut! – Anon
