It happened once upon a time that Mullah Nasruddin was walking in his village and a man came running to him excitedly. “Mullah! Good news! My wife has had a baby!”

“Congratulations!” Nasruddin said, “Is the baby a boy?”

“No,” the man said.

“Is it a girl?”

“Mullah, how did you guess?”

Nasruddin stroked his beard. “From the wise,” he said, “no secrets are hidden!”
