At the end of Indiana Jones and the Last Crusade we learn that Dr Jones (Jr) was named Henry after his father and that 'Indiana' was the name of their pet dog ("I've got a lot of fond memories of that dog..." etc.).
It occurred to me recently that there was a classicist named Henry Jones - Sir Henry Stuart Jones, to be precise (d. 1939) - Greek archaeologist and historian, editor of Thucydides (the inaugural OCT), and the 'J.' in LSJ. An in-joke, perhaps? Probably not.
