"You know, it's at times like this when I'm trapped in a Vogon airlock with a man from Betelgeuse and about to die of asphyxiation in deep space that I really wish I'd listened to what my mother told me when I was young! . . . Why, what did she tell you? . . . I don't know, I didn't listen!" - Douglas Adams, From The Hitchhiker's Guide to the Universe.
