Impressively, considering the first series ended with what appeared to be the fiery deaths of all of the main characters, Psychoville returns for a second run. Reece Shearsmith and Steve Pemberton have fun with the characters that made it, who are mourning those who did not; there are other survivors, however, who don't even make it to the end of this episode. As usual, it's a sharp mix of gruesome horror, black comedy and serial killer fandom.

A terrestrial showing for the second series of the E4 hit. Our gang of asbo superheroes are still on community service, though their habit of disposing of probation officers is starting to get out of hand - and there's the pesky problem of Nathan's immortality to deal with. Full of killer lines and gruesome scenes that wouldn't look out of place in a Hollywood horror, it really is in a class of its own.

Fiver, now rebranded to the attention-deficit-friendly 5*, has been showing highlights of Montreal's Just For Laughs festival for a few weeks now, but tonight's lineup is a cracker worth catching. Noel Fielding brings his energetic oddball surrealism to the Canadian audience. He's followed by Flight Of The Conchords, who are followed in turn by Dylan Moran. If this bill does not amuse you, then there is a strong chance you don't like the funny.

Channel 4's recent attempt at nailing nudity onscreen resulted in Celebrity Naked Ambition, a two-hour clip-show of film stars in the buff. Predictably, BBC4's TV-focused documentary is a more cerebral affair, examining the impact of the sexual revolution on British and American sitcoms, from 1950s shows like Hancock's Half Hour to present-day taboo-busters. There's a decent talking-head roster to back it up.

"A roast is where we show someone we love them by constantly ridiculing them. It's a bit like a marriage," explains host Jimmy Carr, as he lines Barbara Windsor up for the affectionate comedy drubbing. After 50 years in showbiz, she has plenty of friends willing to step up and insult her age, upbringing and career, including Bernard Cribbins, Christopher Biggins, Sean Lock and Alan Carr. Although the jokes are cruel, it's surprisingly loving, and more wholesome than it seems.

David Walliams appears to have found his calling, hosting the first of three two-hour shows dedicated to camp so-bad-it's-good-ness. Tonight, he picks the most misguided scenes on TV, including clips from the BBC's black music show Blackcurrent, broadcast in 1978, though presumably Little Britain's Ting Tong gets a free pass. In future episodes, expect Keanu's clunking performance in Bram Stoker's Dracula and some "flatulence-deodorising underpants".

It's been an extraordinary 18 months for Eddie Izzard, what with all that running about, and the series Marathon Man which captured it all brilliantly. Believe takes it back to the start, looking at his rise to fame, through interviews with his nearest and dearest and the kind of embarrassing old video footage that he'd rather forget, particularly that of his days as a unicycling street performer.

"So - being Santa sucks a big fat cock!" Yes, it can only be the Misfits Christmas Special. Now they've been de-asbo-ed, Alisha and Curtis have bar jobs, Kelly picks up rubbish, Simon is working on his superhero skills and Nathan, of course, is a bad Santa. That is, until they start selling their powers off to raise a bit of extra Christmas money, and those powers pop up in a place they shouldn't be. The greatest Christmas special ever? Possibly.

Though it's back for a special episode next week, this is technically the end of series two and, fittingly, it is one of the best yet. A boy with the ability to move milk ("I call it lacto-kinesis") goes public with his powers, dragging our regular Misfits out of the superhero closet with him. But fame doesn't go as well as they hoped, and Milk Boy's "shittest power ever" turns out to be more dangerous than they could have imagined. With some brilliant lines, stunning emotional scenes and the visual confidence of a Hollywood film, we can only pray for a third series.
