Hitchcock Has No Bellybutton
From an interview between Karen Black and David Savage in Index Magazine, Feb-March 2004:
Karen Black: "(Hitchcock) showed me his belly. He had no belly button."
David Savage: It's true. Very few people know that about Alfred Hitchcock.
Black: "One day I went to see him in his cabin, and he started telling me about his operations. He said he had one where they took his belly button away. He pulled up his little white shirt, and sure enough they had sewn right across the center of his belly, horizontally."
