The Easily Digestible Theory about Life, The Universe and Everything
Never mind the big hole in it.
Dilbert author Scott Adams has an interesting blog entry, about his Donut Theory of the Universe. I call it interesting, because it is a fairly good explanation of something that has piqued the curiosity of mankind for millenia.
(As an aside, it also provides ample fodder for puns: one comment goes, "Sweet theory. I think you are on a roll with this idea. Perhaps some Danish research institute could fund research into your theory. Although, I have to admit I sort of glazed over reading it.")
Give it a read; it's the closest I've ever come to understanding these things. :)
