Forty-two, et. al.
There's been a good deal of discussion about the answer to the ultimate question. I'd rather not beat a dead horse, but I recall that in "The Diaries of Adam and Eve" by Mark Twain there is a similar "creative" math answer. With Douglas Adams' proclivity towards paraphrasing other pieces of literature (the Queen's claim to believe in six impossible things before breakfast from "Alice in Wonderland" as the advertising tag-line for Milliway's, for example), I've wondered if forty-two wasn't "borrowed" from another source.
Any ideas? Comments? Abusive replys? And, please, go a little beyond reminding me what forty-two is in Base 13.
