A neighbour once found Mulla Nasruddin searching for something on the street.

"What are you searching for, Mulla?"

       "My key."

So they both went down on their hands and knees and searched for it. After a long time the other man asked "Where exactly did you drop it?"

   "At home."

"For heaven's sake, then why the hell are you searching outside?"

                       "Because it is brighter here."
