Episode 4 (of 4)
[Watch it (again) on Demand 5.]

Life's Too Short
1x07 Episode 7 [season finale]
Well, that was that. Ricky Gervais says there'll be a second series. Not sure I can be bothered with it.

Lorraine's Last Minute Christmas
Why they didn't keep up the branding and call this Christmas Made Easy I don't know.
[Watch it (again) in HD on iPlayer.]

Merlin
4x13 The Sword in the Stone Part Two [season finale]
Ooh, much dramaticness! All set-up quite intriguing for a fifth -- and, possibly, final -- season.

Never Mind the Buzzcocks
25x12 Christmas Special
[Watch it (again) on iPlayer.]

Outnumbered
4x07 The Broken Santa [Christmas special]
The BBC don't give episode titles for Outnumbered, but this list on Wikipedia has them so they must've come from somewhere. (You'd assume the DVD releases, but this episode doesn't have one yet.)
Apparently this is our last Outnumbered for a while -- there's to be no series next year, but perhaps some specials. I can understand why they might want to finish it off as the kids are getting older, but wouldn't it be nicer to officially end it and give it a big proper send-off, rather than slowly wind it down so it sorta fades away?

Ruth Jones' Christmas Cracker
2011
Shown on BBC Two on Wednesday, and then in a slightly extended version on BBC One Wales-only the next day. But hey, that's on iPlayer, so naturally it's the longer one I've linked to here.
