Looking forward to this one - Mario returns to the screen with this Christmas special tonight where he brings his favourite impressions and funniest characters back for one night only. He'll have plenty of material to work off too since his last series with one of his most popular impressions, Roy Keane, all over the news, and of course the whole Garth Brooks debacle. The comedian will also have a a live studio audience in with him too, with some special guests dropping by.
