This is amazing! Seriously, this is not just Paul Rudd mentioning he was in Ireland for a stag. This is Paul Rudd giving a blow by blow account of his time here to David Letterman, down to wearing the Irish jersey in a pub in Killybegs to the many, many pints of Guinness.
You probably remember the hype from a few months ago when Paul Rudd, Game of Thrones' Peter Dinklage and a whole load of other famous faces were snapped around Ireland looking like they were having serious craic, well they very much were it seems! Watch Rudd chat about it all below...
How cool is that!? Can we trade Paul Rudd in for one of our shite celebrities, please?
