This time, Jack irreverently dives into Britain's undying love for the plucky, humble outsider, looking at how, when it comes to sport, we can't help but get behind an underdog. From 5000-1 Premier League winners to the biggest upset in 1980s snooker, from Kelly Holmes defying the odds to Torvill and Dean turning ice-dancing into a national phenomenon, Jack examines our passion for giant killing and why there's no better or more satisfying a sports story than one that goes against the script.
