I was involved in a spontaneou Haiku crossfire while chatting with a very literate couple on google chat. It turns out that a Haiku is composed of 17 syllables in three lines with 5 syllables then 7 syllables then 5 syllables. Here are two results.

Challenge: toes and dog

Row of ten toes wait
For loving tongue of dog
To wet them laughing

Challenge: manicure and tampon

Cut my nails short
To keep my vulva untorn
When tampon goes in
