Boldly not going anywhere near things like Grange Hill or Teachers, Big School is more like a throwback to the St Trinian's of the 1950s. Co-writer and star David Walliams plays a man known only as Mr Church, Deputy Head of Chemistry at Greybridge School (the nod to Billy Bunter's Greyfriars presumably being the whole point). He's repressed, uptight and sexually inept, and more than a tiny bit reminiscent of Rowan Atkinson playing the title role in Simon Gray's Quartermaine's Terms.

Carey Marx couldn't come to the Fringe last year, because of the small matter of having a heart attack. But, looking on the bright side, the experience has given him his new show, Intensive Carey, in which the comic tells his story without a trace of self-pity and with a keen sense of the absurd.

Christopher Guest and his group of players have been responsible for some of the funniest, driest comedy films of the past 30 years, including Waiting For Guffman, Best in Show, A Mighty Wind and, of course, his masterpiece This Is Spinal Tap, in which he played the tight-trousered guitarist Nigel Tufnel. Now he's directed and co-created (with Jim Piddock) Family Tree, a US-British sitcom first shown on HBO in America.

The celebrated 1955 Ealing comedy starring Alec Guinness, Peter Sellers and Herbert Lom was apparently intended as a cartoonish satire of post-war British decline. In 2013, with the Empire long gone and the country struggling in a new age of austerity, what is there to do when contemplating "the state of the nation" but laugh hysterically?

Equal parts prodigiously talented musician, consistently funny comedian, auteur, theatre performer, free thinker and writer, Reggie Watts is nigh on impossible to pigeonhole. He is a hurricane of furious creativity operating completely in his own lane, hurtling full-speed towards Parts Unknown. Primarily known for his inimitable blend of improvisational music and comedy, each show he performs is completely original, never to be repeated.

You wait years for a female comedy duo to take up where French & Saunders left off, then two come along within a calendar year. Which just about counts as at once. Anna & Katy, who recently had a run on Channel 4, rely for most of their wit on a wide range of silly voices. Watson & Oliver, who have returned for a second series, feel like more traditional sketch artists. They observe and they spoof and even hint at pathos.

The cup of tea is a national institution that brings comfort and good cheer to millions. So is Victoria Wood. Blend them in a pot and you’ve got a pleasing brew called Victoria Wood's Nice Cup of Tea. It might not have been so. When Wood last ventured out into the former Empire it was to visit all the places in the world named after Queen Victoria. The concept felt slightly stewed. Not here.

How do we know Jesus Christ was a Jew? He was still living with his mum at 33 and she thought he was God Almighty. Are you offended? I sincerely hope not and profuse apologies if you are, but that was the first religious joke I remember from my Catholic childhood, and which managed to take a swipe at two religions for the price of one.

As the second series of Zooey Deschanel-starring US sitcom New Girl gets underway on E4, it’s an interesting exercise to revisit first impressions. I note that when the pilot originally aired, theartsdesk was not as harsh as I was on a show which, over the course of its first year, quickly became one of my favourites.
