Any two questions.
A rabbi was always teaching his followers to seek the answers in themselves. But the followers always came back expecting more answers from him.
Finally he set up a booth with a sign: “Any two questions answered €100”.
After some deliberation, one of his richest followers decided to ask and brought two important questions. He paid the money and said as he did,
“Isn’t €100 euro rather costly for just two questions?”
“Yes,” said the rabbi, “and what is your second question?”
