‘Daily,’ said Nasrudin to his wife, ‘I become more amazed at the 
manner in which nature is organized; and the way in which every-
thing upon this earth is in some way planned for the benefit of mankind.’
   She asked for an example.
   ‘Well, for instance, you note that camels have no wings, by the mercy
of Providence.’ 
   ‘How does that help us?’
   ‘Don’t you see? If they had wings they might roost on housetops,
and destroy the roofs, to say nothing of the noise and the nuisance of
their chewing and spitting their cud.’
