A crafty old mountain lion used to hang around a ranch looking for stray cattle. One day he saw a bull off by himself and managed to kill it after a mighty battle. The bull was too heavy to drag off, so the mountain lion decided to just eat as much as he could hold. He ate and ate until he just couldn’t eat any more. This made him feel really good, so he let out a big roar. That made him feel even better, so he roared again. He kept it up until the rancher came by and shot him.
The Moral of this story: When you are full of bull, keep your mouth shut.
