The Hyena was talking to the Baboon, complaining about the King of the jungle.
He is always bossing us around, will you join me and we can kill him, I will be the new king and you can be the 2nd in command, OK says the Baboon.
Later today when he comes on his rounds, I will ambush him, says the Hyena, you join in if I need you, OK says the Baboon.
So the Lion comes through the bushes and the Hyena jumps on his back, there is a terrible fight, and the Lion walks away without even a scratch, but the Hyena is lying in a heap half dead.
He calls the Baboon over, Why did you not jump in and help me, the Baboon replies. You were laughing so much, I thought you were winning.
