The LRB blog has a great Oulipo-style word game:
Think of a word of more than three letters* that, however many letters you remove from the end of it, is still a word (e.g. ANTICS: a, an, ant, anti, antic, antics). Then write all the words out in order and punctuate them to make a (more or less) meaningful sentence.Their example: An ant, anti-antic, antics.
Ban band bandanas. That's all I've got.
