Question:

Why do people say that the meaning of life is 42?

Best Answer - Chosen by Asker: It's from the book Hitchhikers Guide to the Galaxy. They built a computer so powerful it could answer any question. So they asked "the" question.

What is the meaning of life, the universe, everything. The answer, (thousands of years later) was "42"

Moral, sometimes getting the answer still doesn't answer the question.
