"Of course it's not true..." is a recurring response jokingly where either the show's host or one of the team captains denies something. This is mostly used after Paul Merton has jokingly accused someone in the news of doing something. The full phrase is "Of course it's not true that...". Paul often says the phrase himself, but then adds "...but it is." to the end.
