Alfred Hitchcock had no belly button.

(That’s surely impossible. According to KidsHealth, which claims to be “the largest and most visited site on the Web providing doctor-approved health information about children,” a belly button (or navel) is one of the very few features on the body that every single person in the world has. However, I have heard that because the umbilical cord is connected internally at birth, if a wall fails to close around it, you can be born without a bellybutton. As a result some people have never had a bellybutton, but he probably lost his during surgery (he was obese). The rumour persists, and I like to think it’s true.)
