First, you’re in Wisconsin now; that should be cheddar cheese, not mozzarella.
Second, my go-to example of spurious correlation when teaching MBAs was an example from George Udny Yule from 1925. He presented two annual time series, both covering 1866-1911 inclusive, both with pronounced negative trend (and hence a significant positive correlation). One was the proportion of Church of England marriages to all marriages. The other was mortality rate per 1,000 population.
Happily, there was one semester in which one of my students had attended the wedding of her sister, performed in the Church of England. She was able to provide first-hand verification that there is no human sacrifice during such weddings (other than the groom, of course), confirming that the correlation is spurious.
