As the posh team captain on TV panel show Would I Lie To You?, David Mitchell’s only worry is getting away with telling a few porkies to quickfire opponent Lee Mack.
But away from the spotlight, Mitchell admits that having a family of his own – he’s married to TV presenter, writer and professional poker player Victoria Coren Mitchell, with whom he has a four-year-old daughter, Barbara – has increased his fears for the future.
"I’m probably more fearful in middle age," the 45-year-old comedian confesses. "I now have a wife and a child, so in terms of society breaking down and the world collapsing, it’s more frightening than when there’s just you."
His priorities have changed hugely since his daughter was born, he admits.
"When it was just me on my own, things being probably fine was just good enough. But probably fine isn’t good enough when I’m thinking about my child. Suddenly you need things to be definitely fine – and things are never definitely fine, and that’s frightening.
"Your focus completely changes," he adds. "You stay in a lot more and sleep a lot less. But I still do the same job and I love my job in the same way and Victoria similarly, but there’s always something in your mind which is a different priority, a home you have to keep safe and supplied, and make sure that our daughter is happy and seeing us a lot."
Sorry for the silence - have been attempting basic parenthood. And many thanks for all the welcome messages for our lovely daughter Barbara.— David Mitchell (@RealDMitchell) June 4, 2015
His latest book, Dishonesty Is The Second-Best Policy, is a collection of his columns written for the Observer between 2015 and 2019, tackling a plethora of subjects – from politics, the Olympics and terrorism, to rude street names, exercise and the commercialisation of Christmas.
Of course, Trump in the White House and the Brexit shambles have given him plenty of material.
"I wanted to reflect on Brexit and Trump and the way discourse is changing and the end of truth. But I also wanted to make sure there was stuff about chocolate bars and adverts and films, because I am a comedian and it should be a funny take on things."
There are plenty of comedic rants and clearly an underlying anger at many of the subjects he tackles. How difficult is it to be amusing while suppressing such ire?
"I find it’s easier to be funnier when I’ve got something I want to say," says Mitchell. "I find it hard to make neutral jokes. Jokes are what come when you are trying to argue a line, when you trying to say that something is ridiculous or daft, fairly or unfairly criticised."
But his anger hasn’t intensified with the onset of middle age, he stresses.
"I think I’ve always been quite irritable about politics. From the first days when I was doing panel shows, I got myself going through an energised irritability. I’m not an angry revolutionary person, I’ve had a nice stable background, and to come out of that cursing existence would be perverse.
"But the sense of the daftness and stupidity of things has always been my root to opinions that can be entertaining to be read or heard."
Born in Salisbury, Wiltshire, Mitchell is the son of a couple who ran a West Country pub in the 70s, and then moved to Oxford where they became lecturers in hotel management. He began to tread the boards at New College prep school in Oxford, but never thought he had a real talent for comedy.
He failed to get into Oxford University but was offered a place at Cambridge to study history, becoming president of Cambridge Footlights, where he met Robert Webb.
The pair formed a double act which lasted more than 20 years, and he went on to win Baftas for Peep Show and That Mitchell And Webb Look, became the regular team captain on WILTY? and recently starred as William Shakespeare in Ben Elton’s BBC Two sitcom, Upstart Crow.
His path to love was slightly more rocky. Mitchell met Coren in 2007 at a film premiere party and they went out on a few dates, before she emailed him to say that she didn’t think the timing was right.
She went on to find another boyfriend. Mitchell went out and got drunk a lot. He was smitten and didn’t want to date anyone else.
"I didn’t tell my closest friends or my parents of the enormous sadness that overshadowed my life," he wrote in his 2012 memoir, Back Story.
"I was ashamed and I knew what they’d say, ‘Stop indulging yourself in these hopeless feelings. Snap out of it. She doesn’t want to go out with you – she said so’."
He waited three years for her to ditch her boyfriend before making his move – and they’ve now been happily married for seven years. "She’s clever, funny, beautiful," he has said. "I think she’s amazing. She’s brilliant at what she does."
Today, it sounds like she was well worth the wait.
"We laugh a lot at home. I love making my wife and my daughter laugh and they make me laugh a lot. Victoria is as obsessed with humour as I am and that’s how we’re bringing up our child. She may react strongly against it and get massively into Ibsen, I don’t know."
Yet he hadn’t always yearned for a family of his own.
"I hadn’t seen myself as someone who would necessarily get married or have a family. It was very much meeting Victoria which made me think, ‘Oh, now if I don’t spend my life with her it would be awful’, and then having a child came from that. It wasn’t like a life plan."
He’s just finished a town-to-town tour with his WILTY? co-stars Rob Brydon and Lee Mack, in which the three of them performed an improvised show.
"It’s been really good. We just did 18 dates but it’s been great and we may do it again some time," he enthuses.
There’s a tremendous chemistry between the three mainstays on the show – Mack’s common man pitting his wits against Mitchell’s posher persona, with Brydon the witty mediator.
They’re pals outside of work too.
"We get on very well. We see each other socially and it’s been fun going around with them. It’s a nice, easy relationship. There’s no real creative tension. We just sit together and try and think of funny things to say. It’s a very simple aim. There are no artistic differences."
He’ll be starring in the West End stage adaptation of Upstart Crow next year, so at least he’ll have family time during the day, he says.
"It’s in London where I live, it’s just in the evenings, I’m going to miss a lot of bath times but I’ll be around for the rest of the time, and it’s a limited run and I’ve never done West End theatre before. I hope my family will forgive me and I’ll try to be good earlier in the day."
Inevitably, he thinks family life will seep into his comedy at some point.
"It changes the place from which you are speaking. I sometimes see something I said 12 years ago on TV and the joke is a bit harsher than I’d express it now.
"I don’t blame my former self, but it was coming from someone who doesn’t feel the vulnerability that parenthood brings," Mitchell reflects. "The former me could slightly more revel in the comic possibilities of the harshness of the world than I feel able to now. I’ve definitely mellowed."
