Cleaning out old books?

A guy cleaning out his closet mentioned to his antique book-collector friend that he'd happened to throw out a lot of dusty old books in his process.

"There was one bible in particular I couldn't believe I kept." he said, "It looked so old it was almost like it was growing mold."

"What kind of bible was it?" asked the collector.

"Oh I don't know," the guy replied. "Goten or Gooten-something I think."

"You mean you threw out a GUTENBERG BIBLE??" the book dealer asked, incredulous. "How could you?? Didn't you know that those are so rare that one copy could sell for over 4 million dollars?"

The guy paused a moment, considering the implications, and then shrugged. "My bible wouldn't have been worth anywhere near that much," he said. "Some random guy named Martin Luther scribbled notes all over it."
