I took 'The hithchikers guide to the galaxy' and 'The restaurant at the end of the universe' along with me on my boarding trip last week. I read em both. I now get most of the funny references made about fish, mice, the question and answer, towels, vogon poetry and fjords (pining for the fjords???). I can't wait to read the remaining 3 parts of the famous trilogy.
It seems my father has been reading through my copy of 'The art of deception' occasionally. One down, five billion to go.
