My two best ideas this week

1. A cross between battleship and hangman, played with two scrabble boards.
2. There’s an important paper on modality called What ‘must’ and ‘can’ must and can mean.  Someone should write a paper in response to it and called it What “What ‘must and ‘can’ must and can mean” must and can mean.  This isn’t particularly likely, since the paper is kind of old, but if the response paper was good enough, then we can just keep going like that.
