A line of poetry is good, if iambs it does make.(Ooh, a poem about poetry—the serpent eating it's tail, man, the serpent...) Happy Poetry Friday! Your turn.*
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.
* The choice of subject is yours: a poem about poetry, about cyclical serpents, about why you don't like your toes, whatever.
