How you came about...

My sister lies over the ocean,
My brother lies over the sea,
My daddy lay over my mummy,
and that's how they got little me.

If I remember correctly I did a Google search, though I cannot remember the search criteria I used. I seem to recall scanning several referrences, and this one won out because it seemed most tolorant of beginners. I'm very glad I found it, though a few others may be less pleased ;)
