Reddit has resurfaced this 2012 paper from the New England Journal of Medicine titled "Chocolate Consumption, Cognitive Function, and Nobel Laureates," by Franz H. Messerli, M.D.
From the abstract:
Chocolate consumption could hypothetically improve cognitive function not only in individuals but in whole populations. Could there be a correlation between a country's level of chocolate consumption and its total number of Nobel laureates per capita?
For other amusing spurious correlations here you go.
