IF you've seen a hippopotamus defecate you might have wondered why it spins its stubby tail, sending dung flying in all directions. A game ranger will mutter something about marking its territory, while a Bushman will tell you the hippo is showing God it has been eating only grass and not fish - one of the conditions laid down if it wanted to live in the water.

And as if that weren't enough, a week later you're on a Vogon spaceship with some sort of freelance writer and he gives you this fish...
and earwigs. Don't forget earwigs. And botfly maggots in your tear ducts
