Why limit your self to Wisconsin? I used to spend time on uk.rec.motorcycles and they often commented on 'merikins lack of irony.
I have found the use of irony to be wasted on most people so I rarely use it these days, becoming a lost art. I think it has to do with our proximity to Chicago.
Wisconsinites that understand irony also know good beer and not to put ketchup on a brat.
