that not only are hippos the most dangerous animals in Africa, they are also the most disgusting. I had the misfortune of being at the backside of a hippo's enclosure at the San Antonio Zoo once. His disrespect for his watery environment was vividly burned into my memory. Having never forgotten that scene I was informed while watching a Nature show on PBS last week that what I had witnessed years ago was a very common occurrence. YUCK! Let me just say that hippos make hiney sniffing dogs seem well mannered.
