Grandma has a what now?
The following video may not be completely medically accurate, but it does offer one of the cutest/funniest anatomy lessons we've ever heard.
We hope little Bailey will be as amused as we are when she grows up and realizes how funny her anatomical understanding was to adults in 2011, but by then she'll probably be a millionaire from selling "Mommy Doesn't Have Any Penises" T-shirts.
One thing's for sure, watching this video may make you hold off on having kids, if only to avoid awkward conversations like this.
Warning, very NSFW (despite the adorable baby)
