The Irish Defence Forces LÉ Eithne captain and crew took part in a Christmas Jumper Day for CMRF Crumlin’s Tiny Hearts Appeal.
They even recorded a video to encourage people to donate to the Tiny Hearts Appeal.
In the video the captain and crew lip-sync one of our favourite Christmas songs with plenty of awkward dad dancing.
We love it.
The Tiny Hearts Appeal helps fund life-saving equipment and vital research for sick children.
