Mentioned once by Alex Williams. But I was confident few would remember it. And I wanted
to repeat ancient joke about the public lecturer who had a skull as a prop. And after the
lecture, an idiot picked up the skull, and pointing to the formen magnum, said: "Think of
all the good vittles that went down that hole!"
