He's always talked up his Irish heritage, and now Conan O'Brien has finally gotten a chance to walk the walk, too.
When the American TV host and podcaster was in Ireland in January to film his HBO Max travel series, 'Conan O'Brien Must Go' - he also took the opportunity to visit the set of long-running TG4 Irish language soap, 'Ros na Rún'.
O'Brien ended up making a cameo on the show and his episode aired earlier this week - and even saw him speak a cúpla focail, too.
He plays a disgruntled delivery man who is attempting to deliver balloons for a party to the local pub, Tigh Tadhg - but the grumpy publican Tadhg is having none of it.
O'Brien learned his lines phonetically, but he made a fair fist of the Gaeilge, to give him credit - saying "Getting to work with the cast and crew of ‘Ros Na Run’ was a delightful highlight of my trip to Ireland, and I apologise in advance for inadvertently butchering my Mother Tongue."
