Of course, for many of us, this week was not just some normal, ho-hum weeky week: as unremarkable as April 7-14, say, or, I dunno, February 19-26 inclusive. No. This week was Peep Show week. The return of the sitcom locked in a permanent, and fabulous, battle of champions with The Thick of It to be the definitive show of what we must, still, sighingly, refer to as "the Noughties". Peep and Thick are like the John McEnroe and Björn Borg of comedy - sometimes one triumphs, sometimes the other, but for miles and miles around there's no real competition. No competition at all. That one writer - Jesse Armstrong - works on both lends the very real possibility that he might be the funniest person in Britain.

I'm not in the habit of suggesting that the Government should forcibly take sperm samples from scriptwriters, and keep them in a cryogenic vault, in the event of a "comedy emergency" in which everyone funny dies, and we need to restock Britain's gag-writing ability with a concerted breeding programme. But, you know, it might be worth bearing in mind.

As series six starts, Peep Show's profile - once so "cult" that its future looked perilous - has never been higher. The inexorable rise of David Mitchell - thinking lady's beaky sex-penguin du jour - means that even the show's first trailer was subject to mass excitement on Twitter. When we last saw Jez (Robert Webb) and Mark (David Mitchell), they had just found out that either one of them might be the father of Sophie's (Olivia Colman) forthcoming baby. This is an usually "big" plot for the show - after all, even when Super Hans (Matt King) got addicted to crack ("That stuff is more-ish!"), it didn't really take up more than six or seven gags.

Within minutes of the first episode opening, more "big" stuff has happened - Mark has got the terminally feckless Jez a job at his company, JLB - but then JLB goes bust. The sexy business dick Alan Johnson (Paterson Joseph, playing one of the all-time amazing sitcom characters) comes to deliver the bad news: "I just got in from Aberdeen. JLB no longer exists. Thank you, Britain, and good night!" and then is driven away at top speed in a company car.

"That's the last Beemer out of Saigon," Mark sighs. The problem was that, as the episode went on, I noted, with mounting terror, that I wasn't really ... laughing. Yeah, there were a couple of nodding smiles, and the "Beemer" line got what would, on a Laugh Graph, be called "a snorty chuckle", but ... the usual, glorious, abandoned fug of a) borderline hysteria and b) intense emotional anguish, caused by minutely observed cases of total t***tishness, wasn't descending.

I was looking a cataclysm in the face: that Peep Show might have "gone off". We've all got to stop being funny some time. Maybe this was their time. Maybe it was all. Over. Or - maybe it was just a bad opening episode? So I rang people. I blagged. I cried. I sent a courier that cost £38. I got episode 2 sent over, and sat down to watch it in a state of pre-emptive tension rivalled only by the day before my C-section. And oh, thank God - episode 2 is one of the best episodes yet. Mark and Jez have a debate about the temperature setting on a boiler that is less like dialogue, more like an MRI scan of the idiot human brain. Then, later, Jez gets to deliver the line, "I'm a feminist - so I believe women should have any mad thing they want." It's all going to be OK. It's all still amazing. When The Thick of It comes back next month, the skies will be, once again, filled with the boom and clatter of their glorious rivalry.

Peep Show Episode 6.1 Review

A welcome return for the BAFTA-winning sitcom, now in its sixth year and still feeling fresh. You have to commend that longevity in Peep Show, as most British sitcoms, particularly ones with a strong cult following, tend to peter out around the fourth series.

After last season's highlights‚ Mark's stationery cupboard encounter with Dobby, for one‚ it's hard to imagine that Peep Show has any more human awkwardness left to plumb. Wrong! With money tight, even Jez has sought conventional employment, while the imminent arrival of Sophie's baby gives both pause for paranoid interior monologue. As ever, this is uncomfortable stuff, which paradoxically you don't want to end. Generally, you'd imagine what Mark and Jez get up to couldn't conceivably be as bad as what they're thinking; happily, this new series is on hand to prove us wrong.

It's been a busy 2009 for David Mitchell and Robert Webb, what with their sketch show, countless panel games and, perhaps most memorably, cross-dressed Webb prancing his way to victory on the Comic Relief celebrity talent contest Let's Dance. Now the duo return as stars of this ever-improving sitcom. The sixth series finds the hapless flatmates still in denial about one of them fathering Sophie's baby. Mark (Mitchell) wangles Jez (Webb) a job and continues his pursuit of IT girl-geek Dobby. Naturally, his dreams are soon scuppered - this time, by a routine fire drill.

David Mitchell and Robert Webb return for the sixth series of their sitcom. It continues to follow the life and times of the anorak and the wastrel, although by now the characters are getting longer in the tooth. The credit crunch has hit Croydon, the twentysomethings have turned into thirtysomethings, fatherhood looms on the horizon and the anorak celebrates his promotion at work by splashing out on a boiler. Unlike a classic comedy that appeals to all ages, Peep Show targets a peer group who identify with the preoccupations and insecurities of the characters expressed through internal monologues. "[Its success] has a lot to do with being honest about what your life is like and the reality of living in London," says Mitchell.

Good on Channel 4 for keeping faith with Peep Show, despite viewing figures so small they can barely be seen with the naked eye. Now entering a sixth series, socially inept and emotionally stunted flatmates Mark and Jeremy (David Mitchell and Robert Webb) are trying not to think about the inescapable fact that one of them is the father of pregnant Sophie's baby. Wails Mark, "The baby is too big. You can't look at it. It's like the sun." It's up to the decrepit, drug-addled Super Hans (Matt King), who looks increasingly like a monster in a German Expressionist film, to keep the boys from one another's throats. But Mark's world turns to ashes when there's a fire drill at his office and the egregious Johnson (Paterson Joseph) makes an announcement in the car park. If you know little of Peep Show, then probably nothing short of the offer of a free cruise will persuade you to watch it. If you love it, rest assured, age has not wearied writers Sam Bain and Jesse Armstrong's perfect little blackly comic gem.

Following in the footsteps of Kevin Bishop's cringe-fest, Peep Show is back to remind us (and Channel 4) what TV comedy is all about. With Mark and Jez still co-habiting in Croydon and drowning in each other's apathy, it's clear not much has changed (and of course we wouldn't want it any other way). Mark gets promoted and celebrates by getting a new boiler; and also gets Jez a job at his office, providing a platform for a rather brilliant quote regarding a work / porn incident. One of these idiots might be the father of Sophie's baby (anyone else secretly hoping it's Super Hans?). Recently Robert Webb told us that the thing that gets shouted at him most is "Oi, Peep Show". He sighed. But everyone, including him, knows this is the best thing they've ever done by a country mile. Lovely.

Webb 'delighted' with new Peep Show

Robert Webb has claimed that the new series of Peep Show is the best yet.

The return of one of the finest ever sitcoms in the history of the world ever - fact! Sam Bain and Jesse Armstrong's darkly comical flat share work of genius starring David Mitchell and Robert Webb is on tip top form as ever. Considering it's on its sixth series, that's no mean feat. Brilliant, inspired stuff!
