Famous for his dark humour, one-liners and THAT laugh, Jimmy Carr challenges 10 of Britain's funniest comics to spend the day together without so much as a titter. The rules are simple: laugh and you're out. Over the course of the series, they will use every ounce of their comedic talents to try and break their opponents - without cracking up themselves. And it's not just their rivals they need to watch out for. The series is packed with comedy cameos, format twists and surprises designed to lure laughs from both the players and the viewers. It's a stellar line up of British comedy talent as you've never seen them before, but who will be crowned the inaugural winner of Last One Laughing UK?
