POL is a national poetry recitation contest for high school students. On the web page, you'll be able to find a list of approved poems.
POEMS YOU MAY NOT MEMORIZE BECAUSE I HATE THEM AND/OR THEY'RE STUPID:
"Song of Fire and Ice" by Robert Frost. (Frost is underestimated and nuanced. This poem, however, is vomit. Barf)
"The Arrow and the Song" by Henry Wadsworth Longfellow (I love Longfellow, but this one is awwwwwwwful.)
"Auto-Lullabye" by Franz Wright. (Franz Wright is a tough, honest poet whose work I admire. This poem is doggerel.)
"Catch a Little Rhyme" by Eve Meriman (This poem is cute. Cute has no place in poetry.)
