Sitting near some stepping-stones across a river, the Mulla
saw that ten blind men wanted to cross the stream. He offered
to help them over for a penny each.
   They accepted and he started to take them across.
   Nine were safely delivered to the further bank. But, as he was
making his way with the tenth, the unfortunate man tripped and
was carried away by the flood.
   Sensing something amiss the nine survivors began calling out: 
‘What happened, Nasrudin?’
   ‘A penny less to pay,’ said the Mullah.
