Alfred Hitchcock didn't have a belly button. How's this possible?
According to Alfred Hitchcock - The Master of Suspense FAQ
http://hitchcock.tv/HFAQ/FAQ.html
Hitchcock being a mammal had to be born with a belly button, its just how it is for us mammals. Apparently Hitchcock had several operations in the belly area leading his doctors to sow up the bb, but I have never read this from a credible printed source. I suspect its an bizarre urban legend.
