Sometimes you just have to wonder at the sanity of humanity, and there seems to be no better a day to ponder this than February 20 – Northern Hemisphere Hoodie-Hoo Day.

According to the holiday’s creators, this day is all about people stepping outside at noon, waving their hands above their hands and chanting “Hoodie-Hoo”. Supposedly, this is the optimum solution to eradicating the ‘winter blues’ (sufferers of Seasonal Affective Disorder, pay attention). Or perhaps, just maybe, it’s the optimum solution for getting sectioned?

Lucky for us we’ve had more sun here during February than all of summer 2007 put together, so we’re off the hook. That is until you pick up a copy of The Daily Mail and read the headline ‘As Britain basks in sunshine, why heatwaves and malaria “could kill thousands within five years”’. Does “Hoodie-Hoo” work on heatwaves?
