A collector of rare books ran into a friend who told him he had just thrown out an old Bible that he had found in a dusty old box.
The collector’s friend mentioned that Guten-somebody-or-other had printed the Bible.
“You don’t mean Gutenberg?” gasped the collector.
“Yes, that was it!”
“You fool! You’ve thrown out one of the first books ever printed! A copy was recently auctioned off for hundreds of thousands of dollars!”
“Oh, I doubt this book would be worth even nearly as much. Some dude named Martin Luther scribbled all over the margins.”
