The actor just happened to be passing through arrivals

It certainly is beginning to feel a lot like Christmas, particularly in Dublin Airport, where if you were lucky enough to be landing into T2 today, you would have been greeted by the carols from the pupils and teachers of Rush & Lusk ETNS.

One such arrival was only actor Chris O'Dowd who decided to join in with the singers to show some support, and even got to play ukulele.

N'awww.
