This is fun. Tyler Vigen wrote a program that attempts to automatically find things that correlate. As of writing this, 4,000 correlations were found so far (and actually over 100 more when I finished). Some of the gems include: the divorce rate in Maine versus per capita consumption of margarine, marriage rate in Alabama versus whole milk consumption per capita, and honey produced in bee colonies versus labor political action committees. Many things correlate with cheese consumption.
