I can't wait to join
you for a day full of fun
and cool repartee!

I think that I shall never see
A haiku lovely as a tree... (aren't they supposed to have not just 5+7+5 syllables but also a theme having to do with nature?)

WO'N's Blue Haiku above almost-but-not-quite does what I've not seen before: each syllable is a separate word. This one kept it going until the fifteenth...

Any takers?
