Mat Baynton and James Corden's comedy thriller continues. Their two hapless office workers have been kidnapped and need to do some fast talking to explain it all. The plot developments aren't that interesting in themselves (competing factions are after some missing money), so much of the humour relies on the disparity between the mundane everyday and a violent underworld. Baynton's Sam - vulnerable yet principled - is the more interesting of the pair, while Corden is either naive or annoyingly boorish, depending on your viewpoint.

Ann Widdecombe investigates why Christianity has become a favourite for mockery by comedians. She thinks that the jokes are becoming nastier and aimed at belief itself rather than the institution. She wonders what this says about the place of Christianity in Britain today and asks whether any subject should be beyond critique. Comedians interviewed include Terry Jones and Marcus Brigstocke, plus there's input from baroness Sayeeda Warsi and former archbishop Lord George Carey.

The original, full-length comedy marathon at the Edinburgh festival fringe lasted eight hours, so this 60-minute version is very much a boiled-down affair. Introduced by Chris Ramsey and Jameela Jamil, we're promised the highlights from the 40-plus comedians who took part performing stand-up and sketches. There's an array of talent to choose from, including Adam Riches, Ellie Taylor and Celia Pacquola, plus a couple of old timers - Jimmy Cricket and Phil Kay - as well as newer blood, such as Adam Hess, winner of the 2011 Chortle Student Comedy award.

This new comedy sketch show from Seb Cardinal and Dustin Demri-Burns is a mixed bag, both in the range of situations on show and in the variable levels of quality. The lower-sixth humour of vomiting policemen and zombie penis jokes is tedious, but there's more mileage in the scenes with the office flirt who has a new rival to contend with, and a profile of Banksy, who lives a dull life in the suburbs and buys art supplies in Homebase. Some amusingly offbeat stuff here - more please.

A peculiar new show from the Irish funnyman and front of Mock The Week. Based on the assumption that - because he studied maths and theoretical physics at University College, Dublin - he must be quite clever, O'Briain attempts to solve questions and conundrums set by Oxford professor Marcus du Sautoy. The puzzles are the kind of things that made you grimace as a child (the quickest route across two rivers) combined with some tomfoolery (how to get the most kisses at a dance). A comedy guest - David O'Doherty this week - acts as a foil to Dara's logical mind; the equivalent of the kid acting up at the back of the class.

While Sport Relief night tends to be overrun by comedians attempting to locate their inner athlete, here five sports personalities turn the tables by trying their hand at standup comedy. The brave volunteers include England cricketer Michael Vaughan, rugby star Ben Cohen and broadcaster Gabby Logan. Each gets a mentor (among them Patrick Kielty and Jason Manford) to provide advice, inspiration and possibly a shoulder to cry on, as they hone their material for three minutes in front of a live audience.

A one-off, half-hour sitcom starring Armstrong and Miller. It's set in 1908 when the Olympics first came to London, and provides our comedy duo with the opportunity to act like posh nitwits, which they do so well. They decide to enter the Olympics, despite not having done any training and going on a drink-and-drug spree. The script, by Simon Nye, is more Eddy the Eagle than Steve Redgrave. If this is a pilot for a possible series, then the producers need to raise their game.

Kayvan Novak looks as though he is having the time of his life playing the demented area manager Razz Prince. In between acting out his favourite movie scenes (complete with slo-mo sound effects) and making his assistant's life a misery, he offers Ashley and Jerwayne a chance to join the Elite Selling Krew, a shadowy team that may or may not actually exist. Meanwhile, Christopher, fed up with being the new kid, finds himself getting headhunted, while manager Lance wonders whether his empire is all about to fall apart.

A new sitcom from director and executive producer Craig Cash (The Royle Family) that is co-written by Ralf Little (The Royle Family and Two Pints...) and Michelle Terry (Reunited). It's a classic British sitcom set-up - take an institution (in this case a seaside cafe) and use it as a hub for characters to interact and to tease out class, inter-generational and social observations. The comedy and characters are gentle, if at times familiar, but there's a nice pace to it, as though pitched somewhere between Gavin And Stacey and Alan Bennett.

Sean Lock, live at the Hammersmith Apollo in 2010: the style borders on banter and isn't so different to what you'd hear down the pub with your funny-ish mate. He does the Michael McIntyre roam of the stage and has a gesture or physical description for nearly everything. The jokes are a mixed bag - the opener about needing to get out the house because of the kids is pretty pedestrian - but his routine about the fuss the "wheat intolerant" make is worth sticking around for.
