You can tell it’s a poem because it’s swimming in a little gel pack of white space that shows that it’s a poem. All the typography on all sides has drawn back. The words are making room, they’re saying, Rumble, rumble, stand back now, this is going to be good. Here the magician will do his thing. Here’s the guy who’s going to eat razor blades. Or pour gasoline in his mouth and spout it out. Or lie on a bed of broken glass. So, stand back, you crowded onlookers of prose. This is not prose. This is the blank white playing field of Eton.
