Oliver Callan is to present Killing Leprechauns, "a comedy myth-busting exploration into Ireland's culture and its people" on BBC Sounds, "aimed at educating Britain about its neighbour".
The six-episode podcast premieres on BBC Sounds on Saturday 17 September and sees Callan joined by British comedians including Rhys James, Glenn Moore, Sophie Duker and Josh Jones.
"Oliver investigates just how little the British appear to know about Irish politics, sport, customs and culture, using the thoroughly unscientific method of a comedy panel," says the BBC.
"Have they heard of notions, the GAA, do they know there's an Irish language, do they realise what Cromwell did and can they explain the Irish border? Above all, do the British people know just how much they have in common with the Irish?"
Andy Martin, BBC Northern Ireland Executive Editor, Documentaries, Drama and Comedy, added: "People the world over think they know all about Ireland, this series makes them think again.
"A blistering, smart and funny talent, we are delighted to bring Oliver Callan to network BBC audio through BBC Sounds and BBC Radio Ulster.
"This is not a series for the bashful. If you're attached to leprechauns, be warned, many are harmed in the making of this series."
