Comedy Showcase is a platform for C4 to test out new comedy pilots and it begins with the very promising Campus, which comes from the people behind Green Wing and Smack The Pony. It's led by a character called Jonty de Wolfe, a staggeringly un-PC David Brent-alike who takes potshots at 'foreigns and disableds' and is in charge of a low-rent university. The script is from the top-drawer, the cast of university staff fed up and funny... fingers crossed that this one gets green-lit.

One good thing that came out of Bill Bailey's departure from Never Mind The Buzzcocks last year was the fact it has allowed him to concentrate on live work. This whimsical musical comedy show, recorded at Wembley in 2007, is proof of what a treat he is on his own: a set of short and devilishly sweet comic songs and stand-up that takes in everything from Immanuel Kant to a scat-jazz version of the Imperial March from Star Wars.

The finale of this latest series ends on a cliffhanger but not before boiling point is reached when Mark's lies about passing his driving test bite him on the backside. With an unwanted baby and an unresolvable love triangle testing the patience of our anti-heroes, this has probably been the bleakest series yet (tonight Mark seriously considers a one-way ticket to Argentina and a face transplant for the sake of his sanity). Nonetheless, it's also been an absolute hoot.

Good to see Russell Howard, the agreeably warm foil to Frankie Boyle's savage humour on Mock The Week and an excellent stand-up in his own right, has earned his own show. As with Mock The Week, he'll be riffing off the week's news - and since he's a Bright Young Thing, they'll be accompanying blogs and tweets and whatever else.

Mock The Week does a sterling job at, er, mocking the week but we still have a special place in our hearts for its televisual older brother, which returns tonight for an astonishing 38th series. Helping Ian Hislop and Paul Merton with the mirth will be satire's latest poster boy Charlie Brooker and axed Strictly judge Arlene Phillips, and Martin Clunes is back as guest host, a role he's made a good fist of before... though it beats me why they can't get someone permanent in the main chair.

It's fun to see a sketch show so deeply rooted in Britishness and tonight Alexander Armstrong and Ben Miller fly the flag nicely. The posh World War II pilots who are fluent in modern-day teenage slang make their usual welcome appearance, this time facing a firing squad ('we never done nuthin'/'I need my inhalaaar!'), plus the duo try to explain away drunken and drug-fuelled exploits in the manner of Blue Peter presenters. The highlight, though, is the accident claims advert for people who have had an accident reconstructing accidents for accident claims adverts. Mad, but brilliant.

We always welcome more TV time given over to Reginald D Hunter. Unfortunately, the format's a bit clunky in this new series, which sees Hunter teaming up with Andy Hamilton and special guests to chew over a new theory posited by an expert in their field. Still, Hunter does roll out some gems, with tonight's highlight being an argument between himself and Clare Balding over the virtues of Colin Firth. You can probably guess who wins.

Can a bunch of secondary school children possibly do a sketch show that isn't cringeworthy? Well, yes they can - this able troupe have performed live at two Edinburgh Festivals, thus doing their comedy homework. The charismatic Will Poulter (of Son Of Rambow fame) holds it all together, playing a variety of incompetents (teacher, lawyer, doctor, security guard, brain surgeon and, most entertainingly, a 1940s estate agent) in sketches that have just the right levels of surprises and puerility. Overall, a B+.

Pop World has never been the same since Simon Amstell left. Will Buzzcocks go the same way, particularly now it's going down the rudderless route of guest hosts? In fashioning himself into a TV personality, tonight's host, James Corden, hasn't been quite as funny as he thinks he is. Still, he made a good fist of things as a guest captain last year, and he's not the only newbie trying to impress here: achingly hip Noel Fielding is now a permanent fixture.

You'd think that Sophie revealing the father of her baby would make for a spectacular enough denouement but this goes one step beyond, thanks to a tissue of baby-related lies Jez has told to the latest apple of his eye and the fact that a malfunctioning boiler is causing Mark to hit, um, boiling point. Jesse Armstrong and Sam Bain's script is on particularly good form tonight, with Jez's poem F*** You Bush a corkingly stupid highlight.
