From the archives of the webcomic Natural Twenties:
Men and women are very different. For instance, it is now widely accepted in the scientific community that ladies have vaginas. This hypothesis, however, has not been tested because most of the scientific community has never seen any conclusive evidence, and will never see any conclusive evidence. What mysteries the vagina could unlock remain a mystery. I believe that with more resources, we could explore this further and it could possibly point us in the right direction of a Unifying Theory. Yes, I have reason to believe that the vagina-force is the glue that keeps atoms, and the entire universe for that matter, together.
