when i was in high school, my language arts teacher had us write a poem in the format of a native american type of haiku, the syllable pattern was 2-4-7-7-2 instead of 5-7-5, but you get the idea...

rich kulesus (and i think nat synoweic, too) wrote a lovely one that i never forgot:

oh squash
grow squash, please grow
come out of the earth and grow
beautiful squash, we love you.
PRAISE SQUASH!
