I think the answer to the question in reply to "I might use it again" is to simply say "Not on me you won't" and leave. Why would you want to game with this guy again? So he might spring the puzzle of campaign death on everyone again? Or some other puzzle of campaign death? Start your own game, it's not that hard to GM. Be the anti-puzzle, except for this guy's character. For him you can have Solve Or Die Puzzles, Math and Leeches for door opening, Timed Anagram Algebra Puzzles to get served beer in the taverns...
