Cool. My dad is a big crossword puzzler. When I was a kid I asked him if he thought it was possible to start with a wrong word and then finish the whole puzzle.

Cool. My dad is a big crossword puzzler. When I was a kid I asked him if he thought it was possible to start with a wrong word and then finish the whole puzzle. We both thought the odds would be tiny but then he decided to design a puzzle that could be done two ways consistently. He worked on it like a maniac for a few weeks and then came up with two puzzles, one with North/South (or maybe East/West) themes, one with Goethe/Schiller themes (this is all in Germany.) The clues were a bit contrived and I don't remember how big the puzzles were but he submitted them to the weekly "Zeit Magazin" which runs a popular puzzle and published it in the New Years issue.
