I will continue to guess 42 until you watch the movie....
Oh just to let you know there was a bbc mini series on it that was much better than the "Hollywood" movie. Longer but a much better attempt at following the book. I'm sure you could find it online. It's been many years since I've seen it.
Yeah the Hitchhikers guide to the galaxy.
I've already got the movie loaded and ready to go, but I'll look for the mini-series later.
