in ten thousand petri dishes:
I like limericks. I like them so much that when a grade-school teacher gave our class a sheet of partially completed poems, limericks on one side and haiku on the other, I filled out all of the limericks and only one of the haiku. All of my completed poems concerned the adventures of a creature called the moooooooooose, whom I had just invented.
Of course this was hilarious, partly because it ruins the meter, and partly because moooooooooooooooooooooooooooooooose. Ironically, though, only the haiku turned out to be memorable—probably because of its brevity—and moooooooose haiku later became an inside joke among my friends. That haiku was:
Spider's web at dawn
The mooooooooooooose didn't see it
He fell down
A traditional Japanese haiku usually consists of three lines of five, seven, and five syllables, and usually includes both a kireji, or "cutting word", and a kigo, a word that references the season. A traditional moooooooose haiku consists of three lines of any number of syllables, and includes the word "mooooooooooooose", which references the mooooooooooose.
