Hopi Sen has posted two "hockey stick" graphs and asked readers to speculate on what they plot right here. The scale on the lower one starts at 1692 and that'll make the whole puzzle take a few extra hundredths of a nanosecond to solve. Please no copying my answer:
The lower one is clearly the consumption of bananas and other tropical fruit in the UK. The upper one is the number of murders per year in (a) Baltimore and spookily (b) Midsomer, Cabot Cove and every other fictional rural murder location in popular fiction. The only possible conclusions:
Bananas cause psychotic violence.
(Also for Rochdale only: PR Paul “bananas” Rowen can’t win here).
