Someone emailed this to me. I wish I knew more…
A collector of rare books ran into an acquaintance who told him he had just thrown away an old bible that he found in a dusty, old box. He happened to mention that Guten-somebody-or-other had printed it. “Not Gutenberg?” gasped the collector. “Yes, that was it!” “You idiot! You’ve thrown away one of the first books ever printed. A copy recently sold at an auction for half a million dollars!” “Oh, I don’t think this book would have been worth anything close to that much,” replied the man. “It was scribbled all over in the margins by some guy named Martin Luther.”
