John Oliver tore Canada's George W. Bush—Stephen Harper, their current prime minister—a half a dozen new assholes on Last Week Tonight. I pay pretty close attention to Canadian politics (for an American) but even I learned something: I've been breaking the law up there. I've urged my Canadian readers and listeners to vote out Stephen Harper again and again and again... and I had no idea I was risking jail time and big fines.

UPDATE: Why should Americans care about Canada's elecitons? The Guardian counts the reasons...
