(sufi,Nasrudin Stories)

The answer

"There is nothing without an answer," said a monk as he entered the teahouse where Nasrudin and his friends sat.
"Yet I have been challenged by a scholar with an unanswerable question," observed the Mulla.
"Would that I had been there! Tell it to me and I shall answer it."
"Very well. He said, 'Why are you stealing into my house through a window by night?'"
