The world is tearing itself in two. No, it's not a line between Democrats and Republicans or even between Slytherin and Gryffindor. The age-old debate between New York and Chicago-style pizza has reignited after last week's announcement of a U.S. Pizza Museum coming to Chicago's South Loop.

The museum, created by Kendall Bruns, is highlighting America's sweeping pizza obsession through memorabilia. New Yorkers have had a strong reaction to the announcement. The logic goes that if anyone is going to play host to the U.S. Pizza Museum, it should be the home of the pizza rat.
