Would I Lie To You?

Two things can happen when this show really takes off. The back-and-forth over whether a story is true can spiral off in daft directions, as when Julian Clary relates how he's trying to persuade his broody chicken to hatch a duck egg. Or the exchanges can get surprisingly heated. These take-off moments can be too much for the rhythms of the show and end up being edited out. However, here in the final episode of the series, those unseen bits are gathered in for our amusement, and a very enjoyable bunch they are, too.

Deborah Meaden from Dragons' Den strikes me as a hard-hearted rationalist, a no-nonsense type. Would she really be the sort of person to call in an exorcist because the furniture in her house moved around in the night? That's what she asks us to believe as a panellist taking part in tonight's truth-twisting japes and, as always, you're torn: is she clumsily embroidering a lie she has just read off the card or is she deliberately fumbling the telling of a true story? The same dilemma presents itself when Patrick Kielty's anecdote about once punching Muhammad Ali unfolds rather unconvincingly and when David Mitchell explains how he used a calculator to talk to Captain Kirk during episodes of Star Trek. It's horribly plausible.

Do you think Rob Brydon is telling the truth when he assures us that when panellists read statements off their cards, they're seeing them for the very first time?

Or is that a lie as well? That thought might have occurred to you a few times already as all the participants turn out to be surprisingly capable of spinning a believable yarn around the most unlikely of subjects. So either the show is fibbing about the rules or Britain's celebs are actually a far more devious bunch than we give them credit for.

Tonight, no-nonsense Dragon Deborah Meaden insists that she once called in an exorcist after spooky goings-on in her home, Patrick Kielty claims an extraordinary meeting with Muhammad Ali, stand-up comic Mark Watson relives a childhood trauma, Bernard Cribbins holds up his hands to car theft. Worryingly, we're inclined to believe every word they say.

Team captains David Mitchell and Lee Mack are on especially fine form tonight.

In tonight's episode of the comedy panel show, guests Hugh Fearnley-Whittingstall, Rufus Hound, Miranda Hart and Rhod Gilbert compete to disentangle outlandish fact from fiction. Can it be true, for instance, that Fearnley-Whittingstall allows his dog to lick a well-known yeast extract spread off his face? Has Hound visited every pub called The Red Lion inside the M25, apart from four? Comedian Rob Brydon is the host, with David Mitchell and Lee Mack as the team captains.

Hugh Fearnley-Whittingstall, protector of poultry, guardian of gourds and foragers' friend, only gets picked for panel shows because he doesn't kick up a stink when comedians tease him for being a wet hedge-muncher. Here, though, his sense of self-humour is tested to the max when he reads out the line, "Occasionally, I put Marmite on my face and let my dog lick it off." If Hugh's telling the truth, he's an even better sport than we've given him credit for. But, all angles considered, we watched hoping it was a fib. The alternative is just too creepy. Also guesting is Miranda Hart who, thankfully, gets through the half-hour without once referencing her boringly self-deprecating belief that she looks like a man. Best in show is David Mitchell's fight with Rhod Gilbert over the aforementioned yeast-based spread.

Who's telling the truth?

This is a good television show. Would I lie to you? Okay, I'll come clean. This is an average television show, perfectly fine for watching if you have just got in from the pub three sheets to the wind.

Rob Brydon displays the patience of Job in tonight's episode: he waits almost 20 minutes - 20 minutes! - before indulging in an impression of guest Ronnie Corbett. I always thought it was like a tic he couldn't control. Aside from Rob's golfing buddy, the guests are master of the double entendre Julian Clary, doughty Geordie Sarah Millican and chirpy Holly Walsh, who proves sharp with the one-liners. The stories are as tall as ever: Clary has a life-sized statue of himself astride a unicorn in his garden; and Millican once spent three hours on the Asda shuttle bus, for a day out. But the comedy hits the greatest heights when Corbett claims he actually had to ask for four candles in a shop.

Ronnie Corbett is the very special guest on David Mitchell's team tonight. It's a chance for host Rob Brydon to try out his favourite Corbett impression on the real thing and also an opportunity for a very happy Lee Mack to fulfil a childhood dream.

Corbett's presence - small though it is - is a huge part of the show which also sees Julian Clary attempting to explain why he's got a unicorn in his garden and David discussing his unusual childhood friendship with a bucket.

The other two panelists, Sarah Millican and Holly Walsh, may be less well-known but in such legendary company as this they more than keep up their end of the banter - adding up to another perfectly breezy ­half-hour.

Fibbing to their host, fellow panellists and the general public this week are pouty newsreader Kate Silverton, comedian Hugh Dennis, presenter Ben Fogle and Strictly Come Dancing judge Craig Revel Horwood. Dennis kicks off the truth and lies session by announcing that he has to touch his nose every time he says "France". Later, Silverton wants the other team to trust that she once presented the news with her foot in an ice bucket. And Fogle claims authorities on a small island interrogated him because they thought he was a spy. Worse still, he was accused - or so he says - of smuggling breadfruit plants. Laughs abound. There's even a tense moment: Revel Horwood over-investigates Silverton's foot story, perhaps failing to grasp that he's in a comedy panel show rather than an audition for a low-rent detective drama.

Often in this show a panellist manages, through artful stumbling, to make everyone else think that a true story is made-up nonsense. Much harder is to pick up a card and read a fabrication you've never seen before, then convince the assembled wits it happened. There's a solid-gold example of the latter tonight, though to say who pulls it off would of course spoil the point. Aside from that, it's a slow starter, but takes off when David Mitchell cross-examines Kevin Bridges over a horse the latter supposedly bought by mistake in Bulgaria. Also taking part, Prof Brian Cox, a giggly Keeley Hawes and Stephen Mangan.
