A neighbour 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 its being held against me?’
