A shame that what could have been an entertaining foray into the history of joke-telling should be so lacking in humour. There's nothing inherently wrong with the premise of the documentary in which Michael Grade asks whether there is such a thing as a new joke or whether we are laughing at the same things our ancestors did - it's just that it's all a little boring. Ken Dodd, Barry Cryer and Tim Vine are among those pointing the way as Grade discovers what Romans and Tudors found funny, why lettuce was once thought amusing, why a 14th century papal secretary was responsible for one of the first joke books and why the BBC once censored some jokes - chambermaids and lodgers were among the banned topics.

On at exactly the same time and on the same day as Heading Out, Dave's panel show Alexander Armstrong's Big Ask returned for a second series this week.

The format's pretty much the same as before. Alexander Armstrong presents and all three of his guests, in this case Jo Brand, Stephen Mangan and Tim Vine, have to come up with the questions everyone will be asking. Amongst the questions that came up included the subject of the clurichaun (the "leprechaun's naughty cousin"), why the Aztecs were such unsuccessful warriors, and Adam's first wife...who wasn't Eve.

It's a good show, and while the fact it's on Dave means it will never get a big audience (much of it taken away thanks to Perkins's show on the other side) it still deserves a watch because it can throw up some decent moments. One example was a tangent which involved Manga talking about his upcoming role in the film version of Postman Pat - speaking parts only mind, the singing being down by Gary Barlow.

However, perhaps the best thing about this new series is that the idea of the "fact bunker" with Dave Lamb verifying the information has been got rid of. It never worked and I'm glad to see the change made. In fact, I pointed out this was the weakest moment when I reviewed the first series last year. Giz a job, Dave.

Video: Five minutes with Tim Vine

Tim Vine talks to Matthew Stadlen about getting his start in comedy, how he finds jokes that work, his faith, darts and the allure of the one-liner.

The panel show that's like a postprandial version of QI returns with Stephen Mangan, Jo Brand and Tim Vine doing the job of quiz-show researchers and coming up with the questions themselves. This time, Dave Lamb's role as fact-checker has been done away with, leaving Alexander Armstrong in sole charge. Everything else remains the same. There are laughs to be had, especially when the guests stray from the topic at hand - a discussion about Mangan's role in Postman Pat: the Movie being particularly rewarding.

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.

Interview: Stewart Francis - Part #2

Stewart Francis discusses his contemporaries - namely Tim Vine, Milton Jones and Jimmy Carr - finding his comedy rhythm, the Lumberjacks re-union tour with pals Craig Campbell and Glenn Wool and a possible chat show in the works.

Tim Vine & soap stars win first round of Let's Dance

Comedian Tim Vine and a quartet of soap stars - including Natalie Cassidy and Dean Gaffney - triumphed in the first round of Let's Dance For Comic Relief 2013 as the series got underway.

Anyone casually inferring that the title of this 90-minute documentary might shed light on the inner workings of knowing music-hall surrealist Frankie Howerd is likely to be mildly disappointed. The Lost Tapes is far more interested in his stage-and-screen career than his occasionally tumultuous private life. That said, the plethora of footage unearthed here is an absolute treat for any fan of British comedy. Bruce Forsyth, Tim Vine, Ross Noble, Roy Hudd, Galton & Simpson and the eternally youthful Barry Cryer guide us through clips ranging from Frankie's stint at Peter Cook's Establishment Club to his scenes - sadly left on the cutting-room floor - with Wendy Richard and Paul McCartney in The Beatles' Help! to footage of another musical misfire in his role opposite The Bee Gees in the regrettable promotional movie that accompanied their Cucumber Castle LP. Other nuggets include clips from 1973 Up Pompeii! rehash Whoops Baghdad and a 1976 sitcom made for Canadian TV.
