IT's the plaster cast that's never going to be thrown away now that it's been autographed by Chris O'Dowd.
David Flanagan (10), from Killaraght, Co Sligo, asked Roscommon's most famous citizen to sign his cast instead of O'Dowd's new book Moone Boy - The Blunder Years, penned with co-author Nick V Murphy.
David, a fan of the hit comedy TV series Moone Boy, broke his arm while football training.
O'Dowd and Murphy were in King House in Boyle to launch their new book and read extracts from it for children from Scoil na nAingeal Naofa, the Parochial School and St Joseph's Boys' National School, where the Hollywood star was once a pupil.
But once the reading was over, the children got to quiz the Emmy award-winning actor.
And Roscommon's most famous son had some words of wisdom to share with the youngsters.
"It's good to keep your school friends when you get older because they can tell you if you lose the run of yourself," Chris said.
He told them his first acting break came while still at school when he auditioned for a part in the musical Grease.
And although The IT Crowd brought him to a wider audience, he told one pupil this was not his first job.
"That was the first job that people saw but I did loads of jobs before that that were not good enough for people to see," Chris said.
The Boyle-born actor and his presenter wife Dawn O'Porter are expecting their first child in the new year.
