Another oddity from the minds of Reece Shearsmith and Steve Pemberton, the pair who blessed us with The League Of Gentlemen. This time we're spookily flitting between a group of characters that includes a deranged serial killer fanatic, a deranged midwife, a deranged millionaire and - are you spotting a theme? - a deranged clown whose lives seem to be linked by a blackmail letter. As you might expect, this series opener is dark, macabre and gross in places but it does have an intriguing narrative thread. Plus Dawn French is in it - always a good thing.

The duo know their critics well: 'If we didn't perversely include 50 per cent deliberately unamusing material,' says David Mitchell in a self-referential script meeting in tonight's episode, 'they'd have to think of something else to say.' Well, that's us told, then. Happily there are more hits than misses in this instalment.

Much more sure of itself is this distinct and colourful offbeat comedy about four female PAs working for a selection of unhinged execs in a swish London office. Cheerily, the dialogue matches the pacing when it comes to being pert and bouncy: 'Why play the footsie,' says one lovestruck boss, 'when we could have the Nasdaq?' Quite.

Anyone whose day involves extreme surfing in the freezing water and 60ft waves off the rocky coastline of County Clare could probably do with a little warming up. Cue Russell Howard, whose boyish enthusiasm and sizzlingly funny sets are usually hard to resist... but can he win over these adrenalin junkies?

Sean Maguire, last seen in 300 spoof Meet The Spartans, rolls out his splendid torso again for this good-looking TV series parodying ancient times. Now we're in the realm of the Meconian Empire and he's a freedom fighter trying to vanquish evil Chancellor Dongalor (Matt Lucas) before he figures out how to work a baffling weapon of mass destruction called the Eye of Gulga Grymna. Maguire is on good form but the rotund, baby-faced Lucas steals the show; he's contrary, powerful, bloodthirsty, ridiculously attired - and clearly loving every minute of it.

Reggie's existential crisis comes to a head in this final episode, which sees him go into public meltdown during a speech about male grooming products. As ever, Martin Clunes s on top form as the sarcastic monster/creature of pity, and the dialogue has been sucker-punchingly good fun. Fittingly, it all ends up on a beach.

Back when this ramshackle quiz was a bonkers night out at the Edinburgh Festival, the site of deadpan comic Tim Key (nearly) falling off his track-rolling quizmaster chair routinely had us in stitches. Now, said quiz, which asks ludicrous questions then asks text-messaging service AQA to answer them, has made the jump to TV. Mark Watson is the host and tonight's baffled guests are Julia Bradbury and Red Dwarf's Robert Llewellyn.

Poor Paterson Joseph - despite the fact his belle Veronica (Rachael Stirling) shows no enthusiasm for their impending nuptials (that would be because Veronica is really Danny...), he's convinced she's just overwhelmed by his proposal. Yes, Boy Meets Girl has had its plot holes. But the reality-warping gender-swap comedy drama is at its finale now and overall it has worked well: Martin Freeman has done a gentle, tender job of revealing his feminine side while Stirling has been scene-stealingly blokey as Danny/Veronica. Tonight the pair finally meet, hatch a plan to return to their former selves and embroil themselves in a few surprising twists and turns along the way.

The guest in this episode is the bona fide genius Stewart Lee, a man the TV world inevitably can't get enough of now his own super stand-up show has come to an end. But he nearly meets his match with the inventive folk in this series finale, who offer up swimming commuters, psychologically enhanced chickens and a choir controlled by a piano. The show has been a hugely imaginative celebration of the bonkers brainwave, and we'll be sadder than a toddler who's dropped his Mr Whippy if it doesn't get another series... the tumbleweeds blowing across what must be the best props room in TV would simply be too much to bear.

Here's a fun proposition: likeable duo Martin Freeman and Rachael Stirling as two strangers who wind up trapped in each other's bodies. Cue some Life On Mars-style existential crises as the pair grapple with each other's lives and endeavour to return to a normal state of affairs in the first of this surreal but promising four-parter.
