This panel show is returning for its eighth series, the fourth to feature Victoria Coren as host. The series began with guests Mark Steel, Christopher Biggins and novelist Jessica Berens (whom I've never heard of).

For those not familiar with the show, in each programme the guests talk about a normally held assumption and argue against it. In this week's edition the statements they had to argue against were: "Pantomime is an outdated art-form,", "Drunken displays on our nation's streets are a sign of national shame," and "It would be nice to live in a house like Downton Abbey."

While Biggins is obviously passionate about pantomime, not surprisingly it was Steel who was the funniest on the programme, especially with his idea of doing a panto version of King Lear. Berens seemed to add little to the programme, though. Obvious solution - have more comedians and less novelists. Not much else to be said.

Steve Pemberton and Reece Shearsmith's macabre comedy is little more than a series of recurring sketches loosely tied together. But with its wonderfully grotesque gang of misfits and hammy horror, it remains highly entertaining. As the mystery surrounding the missing locket continues, the investigation turns to Christopher Biggins for answers. Meanwhile Robert (Jason Tompkins) manages to escape from Kerry's cottage just as she's cooking up a love spell to ensnare him.

"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.

Christmas has come and gone but if you've still got an appetite for scorched old bird, don't miss the Carry On star's rip-roaring roast. Jimmy Carr comperes while celebs line up to hurl biting but mostly soft-centred abuse at their target. Barbara greets her tormenters (including Sean Lock and Christopher Biggins) with an "'ello' darling" or an "'ello sweet'art", then chuckles like a drunk kookaburra throughout their monologues. Three topics dominate: her age, her bosoms and her controversial support of the Kray twins. The latter is greeted with an almost imperceptible unease and it's curiously entertaining.

This irreverent panel show makes merry tonight with a seasonal special in which host Jimmy Carr asks contestants to guess the results of holiday-themed surveys. If you like your Christmas cheer with a large helping of sarcasm and a dollop of misanthropy, you'll like this. Reliably funny team captains Sean Lock and Jason Manford are joined by guest panellists Jack Dee, Christopher Biggins and Lorraine Kelly.

Funny or easy-to-mock guests booked to provide tonight's festive repartee and laughs include dour comedian Jack Dee, Lorraine Kelly and camp sweetheart Christopher Biggins. Irritatingly, at the time RT went to press, the episode hadn't been filmed, so we can only speculate - wildly - as to its contents. It's Christmas-themed, so expect host Jimmy Carr and contestants to have dressed for the occasion: sparkly antlers; nylon beards; necklaces made of mince pies - that kind of thing. And if Biggins isn't wearing a pantomime dame outfit and lashings of rouge then I'm going home.

My greatest mistake: Christopher Biggins

Christopher Biggins on why a good accountant is an actor's best friend.

This could possibly be the most deranged variety show you'll ever see, the only place on earth where you can watch Christopher Biggins pretending to be Boris Johnson, and Jerry Hall impersonating Katie Price. If that doesn't draw you in, how about Joe Pasquale as Lady Ga-Ga? Or Ulrika Jonsson as David Beckham? No? Surely Vanessa Feltz masquerading as James May is irresistible. As is Eamonn Holmes as Elvis Presley. And David Gest as Elton John. Les Dennis as Gary Barlow... The list goes on, and just gets odder. The All Star Impressions Show could be completely awful or it could be enjoyably barmy. It certainly has a very good pedigree, being co-produced by Steve Coogan's and Vic Reeves and Bob Mortimer's production companies. And it has a certain surreal gloss that could be quite winning. Harry Hill will make a guest appearance, though we don't know whether he will reprise the Morrissey impression that won him Celebrity Stars in Their Eyes all those years ago.

Christopher Biggins as Boris Johnson, Jerry Hall as Jordan, Ulrika Jonsson as David Beckham, Joe Pasquale as, er... Lady Gaga? Yes, here's a show that does exactly what it says on the tin as a stream of TV presenters, actors, singers, chefs and assorted other media-dependent life-forms do their best (which often amounts to their worst) impressions of fellow celebrities. Indulgent but hilarious in parts.

If you thought that George Galloway pretending to be a cat on Big Brother was bizarre, ITV1 has cranked up the weird-o-meter with this programme, which must have been conceived after a heavy-drinking session among channel executives. It involves one famous person doing an impression of another - a concept that could result in an awful abyss of ineptitude and sycophancy, with Stephen Mullhern's commentary digging it into an even deeper hole. But read this line-up and defy yourself not to be horribly compelled to watch. Joe Pasquale as Lady Gaga, David Gest as Sir Tom Jones, Jerry Hall as Katie Price, Christopher Biggins as Boris Johnson, Vanessa Feltz as James May, Tim Healy and Paul Daniels as an elderly Ant and Dec. Pardon?
