Here's how it goes. . .the first line of the next person's haiku must be the same as the last line of the previous person's haiku. (My definition of haiku being just the 5-7-5 thing, not the complicated Japanese naturey thing.)

A crazy rabbit
CI, in this thread the first line of the haiku is the last line of the person posting before you.
We also count syllables - the first line gets 5, the second line gets 7, and the last line gets 5.
