Back tonight for a new run is BBC2's sitcom Twenty Twelve (10pm), about the hapless bunch charged with the task of organising this year's Olympics.

Hugh Bonneville resumes his role as the chairman, dealing in this first episode with a threatened boycott by the Algerians, angry that the Olympic Village's so-called Shared Belief Centre doesn't face Mecca.

Other stars include Olivia Colman and Jessica Hynes.

Back on Channel 4 tonight is prankster Kayvan Novak's Facejacker (10pm).

It's another bunch of toe-curlingly brilliant sketches, including his Terry Tibbs character becoming a fantastically offensive judge in a US beauty pageant.

That, plus an excellent wind-up involving customers struggling to use a supermarket self-service till. I love the bit where the till demands proof of age from an old geezer trying to buy a tin of custard.

Comedian Micky Flanagan turns up in The Secret Policeman's Ball (Channel 4, 10pm).

Recorded on Sunday in New York, this latest Amnesty International fundraiser boasts a huge line-up including Russell Brand, Eddie Izzard, Jimmy Carr and stacks of Americans I should probably have heard of.

Coldplay are on it as well, although they tend to only make me laugh if Chris Martin accidentally slams the piano lid on his fingers.

John Prescott is among Frank Skinner's guests tonight in the last of the current series of Room 101 (BBC1, 8.30pm).

"Labour party legend," is how Frank actually introduces him. Bet he's not been called that before.

And among the former Deputy Prime Minister's gripes? Footballers' goal celebrations. Especially the whole lifting-the- shirt thing.

Frank, who of course is a West Bromwich Albion nut, warms to this theme, pointing out the problem with those celebrations where players have a pre-planned message scrawled on their T-shirt underneath - ready for the dramatic moment when, having hit the back of the net, they can reveal it to the crowd.

His concern is that for some players this wait can be a tad long. "A bloke scored at the Albion about two months ago," he goes, "and his T-shirt said, 'Who shot JR..?'"

No question, Sarah Millican is an excellent, deservedly award-winning stand-up.

And what does TV like to do with an excellent, deservedly award-winning stand-up?

Yep, it likes to give them their own chat show.

The Sarah Millican Television Programme starts tonight at 10pm on BBC2, with guests including Chris Packham and Tracey Cox (oh behave).

New tonight is a sketch show featuring Lorna Watson and Ingrid Oliver, a comedy duo I'm probably meant to have heard of.

Watson & Oliver (BBC2, 10pm) would no doubt love to become the new French & Saunders, but on this early evidence the only thing the duos have in common is they both think they're way funnier than they actually are. Not so much Watson & Oliver, then, as Watson The Other Side.

On Sky1 at 9pm there's a fine new comedy-drama called Stella, written by (and starring) Gavin & Stacey co-creator Ruth Jones.

Set in the Welsh valleys and featuring the impressively slimmed-down Ruth as a divorced mum of three, Stella isn't a laugh-every-20-seconds kind of show, and it's not meant to be, but it's got some strong characters and some great lines and I'm confident fans are going to warm to it.

I'm afraid Debra Stephenson's impersonation of The X Factor's Tulisa shows few signs of improvement (which is why Jon Culshaw's Louis Walsh has to keep addressing her by name).

To be fair, though, Debra's Claudia Winkleman (in her role as host of Film 2011) is still hilarious. Tonight we get Claudia's attempt at reviewing the new Tintin movie.

This Lee Mack sitcom is like ITV1's Primeval. Not because it features time travel and dinosaurs, at least not in tonight's episode, but because, like that show, it was thought to be dead and buried. Instead, I'm pleased to say, it's back for another series, kicking off with a story where Lee has accidentally walked off with a drug dealer's coat.

For a comedian, television can be both a blessing and a curse. Strike it lucky - land your own series, for example - and it can feel as though the sky's the limit. But stick around too long - or, worse, lose your cutting edge - and you can easily find yourself in the wilderness.

What's encouraging about the return of this sketch show, featuring Harry Enfield and Paul Whitehouse, is that it's brought the best out of two long-established comics who many may have felt were past their peak.

Not every sketch hits the mark - they never do - but by the end of the 30 minutes you'll certainly be forgiving Whitehouse for those appalling insurance ads. Well, almost. Look out for guest appearances from Charlie Higson, Simon Day and Timothy West.
