That needs some rephrasing. The correct sentence is: You ARE from Wisconsin if you think Vince Lombardi is God and Brett Favre is his true prophet.
BTW, I tried to convince a pal in northern California that babies in Green Bay hospitals usually wear green & gold hats, that you can be buried in a Packer casket, that some people have entire rooms dedicated to the Packers, that some people decorate their Christmas trees with a Packers theme (including dated ornaments), that some people have gotten Packer G tattoos, and that the town comes to a screeching halt during games--except for the beer run at halftime, of course. He thought I was making it up.
