A neighbor asked Mulla Nasrudin to stand by him in a case
of disputed possession of some grain.
   ‘Did you see the transaction?’ the judge asked Nasrudin.
   ‘Yes, I distinctly saw the sacks of barley change hands.’
   ‘But this case is concerned with sacks of wheat, not barley.’
   ‘That is irrelevant. I am here to say that my friend is right.
As a false witness surely I can say anything without it being
held against me?’
