Tensions between New York and Chicago were already high this week after 1 World Trade Center was named the tallest building in the U.S. ahead of Willis Tower due to its spire, and now Jon Stewart has offered a rather strong opinion on who has the better pizza. The war is on.

Stewart launched a legendary anti-deep dish pizza tirade on last night'e episode of The Daily Show, eviscerating Chicago's trademark. "When I look at your deep dish fuckin' pizza, I don't know whether to eat it or throw a coin in it and make a wish," Stewart said, adding that if he made a wish, "it would be that [he'd] wish for some real f***** pizza."

Stewart added that, not only is deep dish pizza not better than New York piiza, it's not even pizza. To be specific, he called it "a f***** casserole." 

Several shots fired.
