One man’s trash is another man’s treasure, right? So even though this man’s wife told him nobody would buy his old books, he had a feeling that somebody would want them. Or even if they didn’t want the books, they’d buy them just to help him out in proving his wife wrong.
This man quickly sold out of his old books, thanks to his ingenious sign that read, “Prove my wife wrong, buy a book.” We’re guessing that quite a few men would like to have the opportunity to prove their wives wrong for only five dollars. He didn’t say people would actually read the books, only that they’d buy them, and he was right.
