Saw Billy Connolly, a master of putting down hecklers, in Dublin when he first broke there. Times were, as they say, somewhat tense, and on that first visit some IRA supporting twat yelled out: 'IRA!' or something similarly asinine. Connolly paused briefly and you could see he wasn't quite sure how to proceed, then obviously thought: fuck it and retorted: 'Keep talking pal, the bouncers will find you quicker.' Which brought the house down and from that point he could do no wrong for an audience who were already enamoured of him.
