I like coffee...

Why is coffee called "Joe"?  Well, it is over there, anyway.  And it seems it dates back to the First World War when the secretary of the US navy was one Josephus Daniels.  He was a very moral man who saw it as his duty to stamp out prostitution and the consumption of alcohol on naval property.  This resulted in an increased consumption of coffee, with the result that, disparagingly at first, it was referred to as "a cup of Joe".
