Ramona Marquez

Screened a day early to accommodate Strictly Come Dancing's launch tomorrow, tonight's episode centres on Sue's tiresome sister Angela (Samantha Bond), who raises Sue and Pete's ire when they discover she has criticised them in a book. Angela's line in self-indulgent mumbo-jumbo makes her more of a cliché than other characters, so the laugh count tonight is lower. But Karen's (Ramona Marquez) dismissal of a cold caller at the front door is both brutal and very funny.

This semi-improvised comedy continues to assert itself as top dog of British comedies, delivering more laughs per minute than perhaps any home-grown sitcom of the past decade. A bold claim, perhaps, but week after week Outnumbered brilliantly captures the essence of family life today, in which a generation of middle-class parents are in thrall to their bossy children. We all know a Sue or a Pete (Claire Skinner and Hugh Dennis), who tie themselves in knots trying to do right by their impossible offspring.

The programme also packs in a remarkable number of throwaway jokes. Tonight, for example, Pete is late home from work. "Passenger action on the trains," he says. "I think they were lynching the driver." And the children's quirky interpretations of the world are impressively relevant. The flights of fancy from Karen (Ramona Marquez) tend to be the funniest, thanks to the juxtaposition of solemn observation and her adorable voice. Tonight, when Karen is quizzing her mother on terrorism, Sue mentions that when she was young, the terrorism threat came from Ireland. "The Irish? Are you sure?" squeaks Karen. "You mean people like Graham Norton and Jedward?"

"What the hell has happened in this toilet, it's like a urine tsunami," cries Sue (Claire Skinner), prompting tonight's male/female divide in the Brockman household. The girls hit the shops while the men are forced to tackle household chores. Ben (Daniel Roche) concocts a Heston Blumenthal-style dinner with dire consequences. Meanwhile Karen (Ramona Marquez) has her eye on a pair of leopard-print heels. Now in its fourth series, this acclaimed sitcom still has legs. But as the kids get older, their growing self-awareness strains the programme's naturalistic style.

Now back for its fourth series, the main question concerning Outnumbered is, 'Is it still funny after all this time?' The answer would appear to be 'Yes' - mind you, the fact that the first episode went out after My Family probably helped.

Eldest son Jake (Tyger Drew-Honey) is getting into a stage of typical teenage stroppiness, rallying against other members of the family and their attitudes, such as his mother Sue's (Claire Skinner) views of gay stereotypes; troublesome Ben (Daniel Roche) is refusing to wear his Wii safety cord and is under the belief that Jeremy Clarkson is gay; and curious Karen (Ramona Marquez) has an idea for stopping people stealing mobile phones by using bubonic plague.

The parents also have their own trouble, with father Pete (Hugh Dennis) quitting his job as a history teacher over a point of principle (and seemingly his own stupidity) and now working as a supply teacher, meaning Sue is working full time - and Karen is not happy about that. Pete is also having trouble with a eulogy at the funeral of his late gay uncle, which Sue finds amousing.

Outnumbered is still one of the best sitcoms around as far as I'm concerned. The semi-improvisation with the children is a joy to watch, especially when it comes to Karen. Let's hope it continues to keep the pace up.

Tyger Drew-Honey says co-stars are like a real family

Tyger Drew-Honey, star of BBC comedy Outnumbered, reckons that his co-stars Daniel Roche and Ramona Marquez, who play his sibling Ben and Karen, have become like a real family to him.

Another chance to catch the first episode of series three of the delightful family sitcom starring Hugh Dennis and Claire Skinner. Gran takes the Brockmans on an outing to London. Needless to say it's an agonising day: daughter Karen (Ramona Marquez) thinks modern art is rubbish; Ben (Daniel Roache) plays "spot the chav" and stabs one of the Trafalgar Square lions with a ruler; and older brother Jake (Tyger Drew-Honey) suffers serious trauma when he is unable to send a text message. A fourth series is slated for later this year.

Another chance to catch the first episode of the third series of the family sitcom that reinvented family sitcoms. We rejoin the Brockmans on a sightseeing day out in London. Scarily precocious Karen (Ramona Marquez) is grumbling that she wants to go somewhere 'more World War Two-ish', while uncontrollable Ben (Daniel Roche) is climbing on one of the Trafalgar Square lions and stabbing it with a ruler. "Die!" he shouts. "Die, Aslan, die!" Throughout, dad Pete (Hugh Dennis) wears his fixed expression of pain and confusion, like a baited bear. As a portrait of parenthood, it's terrific, even when the plotting, which includes a weary old joke involving a disabled loo, lets the side down. And the dialogue is as sharp as ever. "Look, mummy," says Karen, "I used to believe in wishes and all this nonsense, but then my wish about Ben and the hyenas didn't come true."

The Brockmans are the most convincing sitcom family since the Royles. The last episode in the latest series of Outnumbered was, as usual, perfectly pitched between exquisite gag-packed comedy and fleeting moments of unsentimental family drama.

But even when dealing with Pete's drunken indiscretion with another woman, or little Karen's road accident, writers Andy Hamilton and Guy Jenkin never lost sight of their comic intent. Instead, Karen expressed disappointment that dad had broken his wedding vows - "the vicar's going to be furious" - before harassing a kindly nurse with tacit threats of legal action if her jab hurt more than just "a tiny bit" as promised.

The subtly touching closing scene, in which the realistically reunited parents left hospital with a bandaged Karen, as she wittered on delightfully, said more about enduring family ties than any number of schmaltzy homilies.

Although the youngest kids in Outnumbered are exasperating, they're also unaffectedly charming and clearly far funnier and more real than any other children in sitcom history. Partly improvised by child actors Ramona Marquez and Daniel Roche, their skewed righteousness, ruthless inquisitiveness and semi-logical flights of fancy appear to be an endless source of inspired comedy. I just can't work out whether it's a good thing or not that one of the funniest comedy performers in Britain is a partially scripted nine-year-old girl.

The youngest son Ben (Daniel Roche) is in trouble at school for re-enacting the running of the bulls at Pamplona. Back in the relative safety of the home, he busies himself playing games inspired by Bear Grylls, one of which involves climbing up the north face of the wardrobe - until it is struck by an avalanche. Dad (Hugh Dennis), meanwhile, is still in the doghouse after the night of the bright green cocktails when he kissed a stranger. But all of this pales into insignificance when little Karen (Ramona Marquez) is hit by a car on the way to the school concert and rushed into hospital. Fortunately it isn't serious - just a few bumps and bruises. It's the unsuspecting nurse at the hospital you need to worry about.

Few things are guaranteed to make you panic quite so much as someone telling you not to. That's certainly the case in the last episode of the current series as Jake has to break news of a very worrying phone call to his dad.

With Pete and Sue's marriage rocky this week after he drunkenly kissed another woman, the Brockmans are really going through the mill. But thanks to the resilient skin of young boys all this is water off a duck's back to Ben, who is occupied elsewhere re-enacting his latest battle and attempting to become the first man to scale Everest (or the stairs at any rate) backwards without oxygen.

And Jake is about to discover that even family disasters can have a silver lining of sorts when Kelly - the object of his first serious teenage crush - is recruited to babysit him and his brother. As always though, it's Karen who steals the show during an earnestly hilarious conversation with a nurse in A&E.

As another series ends you can't help but wonder how long Ben and Karen's reign will last and what sort of performers the actors who play them will eventually grow into. Daniel Roche who plays Ben already looks like Alan Davies's tiny stunt-double, while Ramona Marquez would be able to reduce politicians to tears with a line of questioning and logic that would shame Jeremy Paxman.
