A man was walking home late one night when he saw the Mullah Nasrudin searching under a street light on hands and knees for something on the ground. "Mullah, what have you lost?" he asked.
"The key to my house," Nasrudin said.
"I'll help you look," the man said.
Soon, both men were down on their knees, looking for the key.
After a number of minutes, the man asked, "Where exactly did you drop it?"
Nasrudin waved his arm back toward the darkness. "Over there, in my house."
The first man jumped up. "Then why are you looking for it here?"
"Because there is more light here than inside my house."
