April is National Poetry Month. You can find a nice rundown on the Santa Clara County Library web site, with links to resources. An especially nice idea is Poem In Your Pocket Day -- keep a poem in your pocket to share with others on April 14th. It's bound to be more fun than taxes, anyway.
"Kubla Khan" is my favorite poem, but it's kind of long for these purposes, so I don't know what I'll pick. If you want to keep it short and sweet (or sour) I'll refer you to William Carlos Williams and Ogden Nash. More on this story as it develops.
