Right some of the time
The Mulla's clock was always wrong.
'Can't you do something about that clock, Mulla?' someone asked him.
'Well, it is never right. Anything would be an improvement on that.'
The Mulla hit it with a hammer. It stopped.
'You are right, you know,' he said, 'this really is an improvement.'
'I did not mean literally anything. How can it be better now than it was before?'
'Well, you see, before I stopped it it was never right. Now it is right twice a day, isn't it?'
