Nasrudin scaled a wall, and pulled his ladder over into the garden 
on the other side.
   The owner caught him, and asked what he was doing there.
   ‘I…have a ladder for sale,’ improvised Nasrudin.
   ‘Fool!’ said the householder. ‘A garden is no place to sell a ladder.’
   ‘It is you who are the fool,’ said the Mulla, ‘for you did not know
that a ladder may be sold absolutely anywhere.’
