When I was a little girl, my great-grandpa (pawpaw) used to tease me about my belly button and say that a little ducky swam by and left his butt in there. Sure enough, if you look at the folds of my belly button, it looks just like a little butt! I actually believed him for quite a few years, until I got old enough to realize, that, well, 1) ducks don't have butts and 2) how was it going to get said butt into my belly button anyway??
This is one of the few memories I have of my pawpaw, and it's a special thing that I remember about my childhood. I was telling Annabel this story the other day and asked her if she thought a duck had left his butt in her belly button, too? She looked pretty hard at her belly button and finally said, "He DID leave his butt in there... and he left his penis, too!!"
Oh. My. Goodness. What am I going to do with this child?!?
