Thespian Domhnall Gleeson was inspired to do his part for a good cause after writing a half-hour show entitled Immaturity For Charity which is due to air on RTE on December 27.
And he has managed to pull in a stellar cast of actor pals for the skit, with stars Love/Hate's Robert Sheehan, Hugh O'Connor and, of course, his famous dad all mowing in to help him.
Producer Juliette Bonass explained how he wanted to help raise funds for St Francis Hospice in Raheny after both his grandparents died there a few years ago.
"He had that personal connection to St Francis and he really wanted do something to help them out," she said.
"It's a great facility, the staff are amazing but while people have heard of the facility, what they don't realise is just how lacking in funding they are. We tried to think of a way to help raise some funds in a creative way and he came up with the idea of doing these comedy sketches."
She said Domhnall then rang around all his pals in the acting world to see if they wanted to come on board and was "overwhelmed" by the response.
And Ms Bonass added how the well-known cast members were more than happy to embarrass themselves on national television for a good cause.
The project was filmed over the course of a week last March and brought together a team of 50 of Ireland's best-known actors, writers producers and film crew.
"Everyone wanted to do it and wanted to help out. They all did it completely free of charge and jumped at the chance to do it. We couldn't have hoped for a better reaction as they were all so forthcoming with their time," she added.
RTE is going to donate the fee from the sale of the comedy short towards the hospice.
It will also be posted online after it airs on the Immaturity for Charity donation page, where members of the public can make a contribution to the hospice.
