Whats a good poem to present?

Ok, well I have this school ignment were I have to choose a published poem, and present it to the cl. We also have to talk about what the poem is about, and what literacy techniques are used (simile's, alliteration ect.) I'm in grade 8, and i dont know what poem to present. I want it to be something fun and exciting, and one that I could present with alot of expression. Any ideas of good poems? Please include name of poem as well as author. Thanks!
