Back when I was still an X-Phile, there was a series of stories written (I believe it was the result of a challenge, but it was ages ago now, so the memory is badly faded) known as "155 Words" - because that was their length. And there were some 154 Words, and some 156 Words, and nobody cared. (Most of 'em are still on Gossamer, if you should be curious.)
