[Kevin Wald] also had a crossword in the Mathematical Intelligencer that proved the irrationality of Phi. Several of the clues are "first part of the proof", "second part of the proof", etc. The clever thing is that the crossword requires a diagram, as they generally do, and the proof requires a diagram, as they often do, but it turns out to be the same diagram!
