A dog had fouled the road between two houses. Each neighbour claimed that the other should clear it up.
Nasrudin was in court when the matter came before the summary judge.
This judge resented Nasrudin's claiming to be an adjudicator in common law. The case was difficult, so he decided to take Nasrudin down a peg or two.
'I will abide by your decision, Mulla Nasrudin,' he said, 'since this is a difficult case. You have the final word.'
'My decision', the Mulla immediately answered, 'is that since it is for the judiciary to clear up matters in dispute -- you should clean it up.'
