A man is lost in the dessert for weeks and meets a hippo... ""Hey Hippo, would you tell me where the Great river Nile is?"" The Hippo answers: ""I don't know, let me go ask my brother."" So the hippo leaves and the man waits around for weeks dying of hunger and thirst. After a month of suffering he sees two hippos coming on the horizon. ""So?"" he asks. ""Well man, this is my brother, he also doesn't know where the Great Nile is, but we came back to beat you up.""
