Poetry Friday: Or Not

As mentioned, I'm reading this book, and I've got poetry on the brain (not necessarily good poetry, mind you, but poetry nonetheless). Let's declare this Poetry Friday and share. Here's mine:

A line of poetry is good, if iambs it does make.
A line of poetry is good, if rhymes it shan’t forsake.
If metaphor and simile, it casts about like seeds,
Up shall grow the finest poem, amongst the prosy weeds.
Or not.

(Ooh, a poem about poetry—the serpent eating it's tail, man, the serpent...) Happy Poetry Friday! Your turn.*

* The choice of subject is yours: a poem about poetry, about cyclical serpents, about why you don't like your toes, whatever.
