Lets see if this will work.
I am going to start a poem. The idea is for someone to post TAG in the comments. The first person who does this then takes my line and goes to thier own blog. They make a new post that reads:
It's a game of poetry tag. Be the first to post TAG in the comments. Then take these lines and add one, in a post on your own blog, along with these instructions. Whoever adds the nineteenth line then takes the poem to Poets Who Blog at http://poetswhoblog.blogspot.com/ and puts the whole poem in the comment section there. Each person who plays need to also mention what site you were at when you found the poem so that other bloggers can follow the breadcrumbs back to this poem. You can play more than once but not twice in a row.

The sound shook his bones
