Everyday,Mulla Nasruddeen used to transport dry grass, to the other state on a donkey.The custom officers were thinking that he was smugling something in it.They used to check each time and sometimes they burnt the grass too.They failed every time to find what he was smuggling.Mulla was getting richer day by day.This happened for a long time,over the years.After some decades or so,one of the officers got retired and Mulla had also left transporting grass.One day,the Officer met Mulla and asked him,"Mulla,I know you were a smuggler,tell me the truth now.What was that you were smuggling?".Mulla said "Nothing was there in the grass.Instead I used to smugglle DONKEYS...!".
