Dave, you crack me up!!!
Years ago, when I joined and saw the question "what is five times five?" I answered "twenty-five," because the question was posted in the written version of the number "five," and not the numeric symbol "5."
After being rejected twice, I finally figured it out, and felt quite foolish!! (The professor who presided over my Logic class at Lone Mountain would have beaten me over the head with the accompanying class textbook for not thinking things through.)
But then I also saw how clever the question was, and how we had to "think outside the box" to avoid spammers.
