Whilst I enjoyed the mental exercise and learning something I didn't know about 2005, I just can't picture when I would actually do such a join in real life. Is there a logical, meaningful example that was the basis of this problem ... and if not, does anyone have any ideas of when you'd prefer results which only join multiple values in this manner?
Actually, there are a wide variety of questions on this very forum asking for practical solutions to this exact problem. In most cases these are reporting requirements.
