Channel 4 must be struggling for shows to fill their once-feted Friday night slot, as 8 Out Of 10 Cats, which finished its 11th series a mere month ago, is already back for another outing. Jon Richardson, now firmly ensconced in the role of "team captain who is not as funny as Sean Lock", is joined by comedian Holly Walsh, while Lock, whose quick, absurdist turns of phrase are forever the strongest element of this tired format, gets some help on the one-liner front from Richard Ayoade.

Video: Amnesty at the fringe: Stand Up for Freedom

Amnesty International has always had great support from comedians, who value the right to freedom of speech more than most. At last week's Stand Up for Freedom comedy night at the Edinburgh festival, a 1,200-strong audience watched the best of fringe comedy and also did their bit for human rights. Here's a sneak peek at the sold-out show, with Ed Byrne, Holly Walsh, David O'Doherty and Jenny Eclair.

An interview with Holly Walsh

Holly Walsh is a comedian and comedy writer whose comedy career started whilst working in art galleries and writing for Jo Caulfield on BBC Radio 4.

The first series of this panel game went out late at night, but series two has won a place in the post-news chuckle slot. The premise is simple: host Charlie Brooker invites three panellists to share their experiences of life's low points (Modern Life Is Putrid is one discussion point) or dream up worst-case scenarios in topics ranging from soaps to boy bands, and off they go. It's pure Brooker territory, of course, but he's a master at highlighting the comedy of the dark side, and it's done in a warm, mutually-inclusive, sharing way that's curiously uplifting. And funny. This episode features Rufus Hound, Holly Walsh and Mark Watson and it's a cracker. The only downside is that you won't be able to see Hound's magnificently voluminous trousers.

Rob Brydon displays the patience of Job in tonight's episode: he waits almost 20 minutes - 20 minutes! - before indulging in an impression of guest Ronnie Corbett. I always thought it was like a tic he couldn't control. Aside from Rob's golfing buddy, the guests are master of the double entendre Julian Clary, doughty Geordie Sarah Millican and chirpy Holly Walsh, who proves sharp with the one-liners. The stories are as tall as ever: Clary has a life-sized statue of himself astride a unicorn in his garden; and Millican once spent three hours on the Asda shuttle bus, for a day out. But the comedy hits the greatest heights when Corbett claims he actually had to ask for four candles in a shop.

Ronnie Corbett is the very special guest on David Mitchell's team tonight. It's a chance for host Rob Brydon to try out his favourite Corbett impression on the real thing and also an opportunity for a very happy Lee Mack to fulfil a childhood dream.

Corbett's presence - small though it is - is a huge part of the show which also sees Julian Clary attempting to explain why he's got a unicorn in his garden and David discussing his unusual childhood friendship with a bucket.

The other two panelists, Sarah Millican and Holly Walsh, may be less well-known but in such legendary company as this they more than keep up their end of the banter - adding up to another perfectly breezy ­half-hour.

Worried crowds at the annual International Worthing Birdman contest looked on as Holly Walsh was taken from the sea by a lifeboat crew, strapped to a spinal board and driven to hospital in an ambulance.

Dara O'Briain presents a festive edition of the comedy panel show. The series's regulars - Hugh Dennis, Russell Howard, Andy Parsons and Frankie Boyle - offer their reflections on Christmas and review highlights from the series. There are also contributions from other nimble-witted comedians, including Fred Macaulay, Holly Walsh, Milton Jones and David Mitchell.

This week the pop quiz is the launch pad for the manic wit of regular team captains Noel Fielding and Phill Jupitus, guest host Alex James and panellists Peter Serafinowicz, Holly Walsh, Newton Faulkner and Jessica Origliasso. That means there's a range of comic styles as divergent as this show's musical tastes usually are from the current Top 40.
