A Christmas special of Mrs. Brown's Boys will air tonight on RTE One and BBC One.
As the festive season rolls around once more in Finglas, Agnes is recruited to the church choir but is under strict instructions from Father McBride that there is to be no singing - and certainly no dancing.
Meanwhile, a Christmas tree shortage means Buster will be trying to impress Agnes by any means necessary.
Dermot and Buster have also organised this year’s festivities at Foley's and have put together a Murder Mystery night in aid of alcoholic greyhounds.
You can watch 'Mrs. Brown's Boys Mammy's Mechanical Merriment' on RTE One at 9:35 pm or on BBC One at 10.20 pm tonight.
If you miss out on the household favourite due to its timing, you can watch it back at any point after this on the RTE Player.

The second installment, with the title ‘Mammy's Micky’, will cover the theme of reconciliation and fresh starts - but not everyone seems to be on board with the idea.
Grandad’s brother, Micky, has just been released from prison and decides to stop by for a visit.
Everyone except Grandad is suspicious when he shows up asking for €5,000 to invest in a South African gold mine.
Winnie is on a daredevil mission to change the direction of her life while Mrs. Brown’s boys are forced to have a heart-to-heart.
The first of a two-episode special will air tonight with the second one hitting screens on New Year’s Day.
