Mulla Nasrudin

What is it all for?

    Nasrudin lay under a mulberry tree one hot summer’s day, looking at
some enormous water-melons which grew near by. His mind turned to
higher things.
   ‘How is it’, he wondered, ‘that an immense, impressive tree like this
mulberry brings forth such puny little fruits? Look at the miserable,
weakling creeper which produces such huge and delicious melons…’
   As he was pondering the paradox, a mulberry fell and landed on his
shaven head.
   ‘I see,’ said Nasrudin. ‘That is the reason, is it? I should have thought 
of that before.’
