Believe me, some people REALLY believe that Eastwood character's name is Joe in the first, Manco in the second.. etc and they even get annoyed if you explain the truth to them, I guess that's what I get from hanging around imdb forums.
Anyway, for those who might be wondering about Manco, it is actually "monco" and this is what it means http://www.wordreference.com/iten/monco
