Pay one penny les

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?"

'Don't worry you have to pay a penny less,' said the Mulla.
