Pick of the Day

The Den , 6.30pm, RTÉ One

This is probably the best way to kick off Christmas week, as the reunited Ray D'Arcy and his old after-school alien buddies Zig and Zag, and Dustin make their final appearance together before the Big Day.

No doubt they've planned something spectacular - tonight's show just cannot be missed, with the likes of Star Wars' legend Mark Hamill, Derry Girls' Nicola Coughlan and Mundy all taking part in the festive fun.
