Sandi Toksvig bid The News Quiz (Radio 4, Friday) farewell this week. She had been with the show for nine years, 28 seasons and 222 episodes, which is a good innings by anyone's account. Dressed in tuxedos, her panel - Jeremy Hardy, Francis Wheen, Andy Hamilton, Phill Jupitus - looked like something from the early days of BBC Radio, and put in a relatively subdued performance. Like them, I'll miss her laugh, her ability to poke fun at herself, her infectious good nature. But I'm also intrigued to see whether Miles Jupp, named as her successor in this week's announcement, can breathe new life into a series that has become rather cosy and unsurprising of late.

As a younger show with an "open door" submissions policy - meaning that anyone can send in material for consideration - the topical sketch series Newsjack (Radio 4 Extra, Thursday) ought to be edgier, weirder, less formulaic than The News Quiz; but ends up, somehow, being just as complacent. Currently fronted by the comedian Nish Kumar, with assistance from a revolving cast of comics and actors, it's one of a small group of original, non-archival series on 4 Extra.

This week's half-hour instalment was dispiriting in the way that only really unfunny comedy can be. A skit about a plane that had been forced to land at Heathrow because of a broken lavatory careered out of the radio and landed with a tin clunk on the floor. The nadir was reached during a skit about politicians doing drugs, in which Nicola Sturgeon was represented by someone doing a generic Scottish accent, David Cameron by someone who sounded vaguely like Ed Miliband, Ed Miliband by someone who sounded like a young Janet Street-Porter, and Nigel Farage by a woman making no attempt to do an accent at all.

Why does BBC radio so consistently fudge this kind of thing? Neither series is doing anything that pushes a boundary, finds an edge, or ventures anywhere outside of an ideological comfort zone. Chris Morris's On the Hour, commissioned by Radio 4 nearly 25 years ago, retains more bite in a single sketch than they managed across an hour of broadcast time. Here's hoping it doesn't take another quarter-century for the BBC to try something different.

The News Quiz (Radio 4, Friday), Britain's longest-running series in this genre, is also the lead offender in terms of bad topical comedy. Worn smooth by nearly 40 years of regular airtime, it is now as cosy and predictable as pie and mash; to my knowledge it hasn't caused a sharp intake of breath since 2011, when the host, Sandi Toksvig, made a pun about a four-letter-word.

Listening to the current - 86th - series, I've become convinced that if technicians programmed a computer with a wide-ranging set of News Quiz input-output rules ("Middle East peace talks = joke about Tony Blair"; "Education cuts = ironic reference to Eton," etc) and fed it the week's current affairs, they could accurately predict the show's scripts.

The only curveball in this week's edition was that regular panellist Jeremy Hardy had been asked to chair, as Toksvig was off sick. This seemingly humourless move had been singled out as a rich source of in-joke material by the writers. "I am the host this week because Sandi has been suspended for biting the producer's knees when her pre-show herring was not chilled to the correct temperature," Hardy began (Toksvig is 4ft 11in and from Denmark). He later returned to the theme during a limp segment about genealogy: "everyone on this panel will have a little bit of Scandinavian in them; could everybody just make sure they haven't sat on Sandi?" Unsmiling, I added "ST absence = joke about smallness + Scandinavia" to the list.

Wossy's production team have really come up with the goods tonight, netting five sparkling guests who, between them, should please almost every part of the audience. Top of the bill is Danny Boyle, whose direction of the Olympics opening ceremony last summer propelled him from well-regarded filmmaker to cut-and-dried national treasure overnight. He'll be talking about that experience, as well as his latest movie, Trance, and his recently revealed plans to make a sequel to Trainspotting within the next few years. Fans of the director should savour the moment, as Boyle hardly ever gives TV interviews.

Following him, Deadwood star Ian McShane and Skins alumnus Nicholas Hoult drop in to discuss their new film, Jack the Giant Slayer (not a remake of the 1962 film, but basically Jack and the Beanstalk reworked with Hollywood levels of blood, guts and brouhaha).

Last but not least, Blur frontman Damon Albarn and 69-year-old soul hero Bobby Womack are on hand with live music from The Bravest Man in the Universe - the wonderful, strikingly poignant album they made together last year.

It's hard to resist quoting from the press release announcing the return of this panel show, which described its host as "Pointless presenter, comedian and actor Alexander Armstrong". Unintended slurs aside, this series promises unscripted entertainment - tonight features Jo Brand, Tim Vine and Stephen Mangan.

This hit-and-miss series of comedy shorts continues tonight with a promising offering starring and co-written by former Fast Show star Simon Day. He plays a cheery personal trainer whose clients include a Hollywood-bound actor and a young boy whose mother he has taken a fancy to. Look out also for The Royle Family's Liz Smith in a cantankerous supporting role.

The fourth series of this reliably funny stand-up comedy show opens with a bang tonight, as Al Murray's Pub Landlord embarks on an open-top tour of the capital. "The whole world looks to London," he says proudly, "and then sends its slack-jawed teenagers to chain-smoke and shoplift in the Trocadero." The tone set, Murray proceeds to give a fine, typically provocative performance in front of a paying crowd at the Shepherds Bush Empire before introducing support performances from Richard Herring and Andy Zaltzman.

To celebrate the 30th anniversary of Five Go Mad In Dorset - a brilliant hour-long satire of Enid Blyton which went out on Channel 4's opening night in 1982 - G.O.L.D. has commissioned a new Comic Strip episode featuring the original cast. Entitled Five Go to Rehab, it follows Julian (Peter Richardson), Anne (Jennifer Saunders), George (Dawn French) and Dick (Adrian Edmonson) as they reunite for one last adventure. Perhaps inevitably, it lacks the revolutionary zeal of the first outing, but is nevertheless genuinely funny.
