My favorite poem has to be Belinda Blue. Why? Because of what happens in the story (it has about 5 paragraphs exclaiming that she is MAD, MAD, MAD, because her mom asked her to eat one green bean).
The main idea is that Belinda was asked to eat a green bean. The lesson from this poem is that you should eat your vegetables.
I would recommend this to anybody that likes a funny and entertaining story.
