Chicago and all things Irish

Our conversation this morning at work went a little like this:

Chicago the windy city, dyes its river green on St Patrick's Day. The man with the porn star name said he knew some irish folk songs that mention Chicago (he's irish), "but I'm not going to sing any forya". "Oh go on, gowan, gowangowangowan" (a la Mrs Doyle). That's very typically irish, they always say, "You'd like a cup of tea wouldn't you? Oh you would...but everyone else is having one. You'll have one anyway.." He also said they were very inquisitive (read: nosy) like when asking directions "could you tell me the way to the nearest post office?", to which the reply "Personal letter is it?"
