I wasn't expecting that at all

Daniel O'Donnell, that will be the second Irish contestant to take part in the show, two years in row.
I can honestly imagine that Brendan O'Carroll, whose wife took part last year, will end up making a reference of some kind to him on this year's Christmas special of Mrs Brown's Boys. I would be very surprised if he didn't. After all, both are really big fans of the show and I do seem to remember Tristan McManus making a guest appearance in an obvious reference to his Strictly partner.
