Death Comes to Pemberley
Part 2 (of 3)
[Watch it (again) in HD on iPlayer.]

Friends
6x17 The One with Unagi [5th or so watch]
6x18 The One Where Ross Dates a Student [5th or so watch]
Or, The One with Joey's Twin ("How you dooo-iiin!"), and... no, the second one's good.

Not Going Out
7x01 The House [Christmas special]
Weird for a one-off Christmas special to be the first episode of a series that isn't immediately following it (because it's a one-off, innit). But that's what the episode guide says, so there you go. Either way, I thought it was good fun, and suitably Christmassy in that ghost story tradition... with plenty of laughs too, of course.

Vicious
2x00 Christmas Special
More laughs! It may be a little blunt and old fashioned, but I like Vicious.
