Only four remaining comics are left in this mission to find the funniest Gaeilgeoir in all the land. They get a masterclass tonight from comedian Colm O'Regan, the man responsible for bringing the Irish Mammy Twitter account, books and even tea towels into our lives. All four of them will also have to take to the stage at the Samuel Beckett Theatre in Trinity College Dublin in front of guest judge Ronan Mac Aodha Bhui. Jokes as Gaeilge wha'? Fair play to them, or as you'd say Gaeilge....em... yeah, never mind.
