I had a friend who had been a zookeeper at the LA Zoo (I think that was the zoo). He was standing near a truck that was picking up a dumpster full of hippo poop. The dumpster slipped and fell over on top of him. He almost drowned in hippo poop. They rescued him in time and resuscitated him. I always wondered if they gave him mouth-to-mouth resuscitation.
Wow, hippo poop. That sounds like more than even my older brother does.
