Hey Cindy -
That's a Mother Goose rhyme. It's in one of the old books of kids' rhymes I have at home... but I won't be home for a bit! I'll try and find it in other places, but I recommend going to your local library, finding books of complete Mother Goose (Inasmuch as there can be a 'complete' MG...) and looking for it there. I remember reading it.
If not, I'll look it up when I get home...
