Last One Laughing UK returned for its second outing of the year yesterday, dropping the first three episodes of its Halloween special season yesterday (23 October). Jimmy Carr and Roisin Conaty welcomed a host of new comedians and returning favourites back for another game of trying not to laugh, while attempting to make the others crack.This time around, there's a load of spooky themes, while a new rule means that the contestants aren't allowed to scream either.
