I don't really like magnetic poetry. It's too limiting (or I'm too inflexible) for me to get really creative with the limited selection of words it offers the writer of casual kitchen poetry. However, I do really like this poem that my wife & I co-created with the magnetic poetry set that someone gave us about dogs. It's meant to invoke the young retriever who's still learning how to be a dog.
remember to retrieve
no pooping on toy
no devour cat
For another fun poem about dogs, check out Kay Ryan's "Fool's Errands" in The New Yorker.
