The gang are back for ten new episodes of one of America's most popular shows. One of the writers, Rob McElhenney, had admitted that part of the show's continued success is not having to deliver a typical full season of 24 episodes, meaning that Hollywood's loss is your gain. Guest stars for the latest run include comedians Dax Shepard and Keegan Michael Key (Key & Peele), and retired baseball star Wade Boggs, as Charlie and Co. try to beat his long-standing in-flight drinking record in the opening episode. It promises to be a typically messy affair that you'll love, even if you're not yet a fan of the show. Season eleven of It's Always Sunny in Philadelphia begins on US telly this week, so get yourself up to speed and binge-watch season ten now.
