Oh, what a pain! I'm sure there must be a way to adapt any number of sea shantys. Or there's "Pick-a-little, Talk-a-little," from the Music Man. I remember about seven years ago having two kids with nits- and in the midst of the process I had to have an emergency appendectomy (No, I don't think it was related to the nits!) and came home from the hospital with a head full of my own! Yuck!
