Also throughout the 'season', festive episodes of shows such as Bottom, Harry Enfield and Chums, and Alistair McGowan's Big Impression on Dave, and the usual on UKTV Gold, Paramount et al. Check listings for times.
And that's about it. I've tried to highlight a selection of different stuff, including Simon Nye's panto adaptations, BBC One's big Oliver Twist drama series, all 13 episodes of the Carry On Laughing sitcom, and a few other films, documentaries and shows related to comedies or featuring notable comedians. Shows highlighted in bold are, as far as I'm aware, new Christmas specials (although it's possible I've missed out a few). Oh, and the Red Dwarf episodes early mornings on BBC Two are series one, in order. If you've got any questions about any of the programmes listed (further details, episode number, etc), post and I shall answer. 
Oh, and let me know if I've missed anything out which you think needs adding.
