David Mitchell is fast becoming king of the panel game. He's scarily good at them, so it's no wonder he's called on to lend his wits to shows from QI to Mock the Week, and from Have I Got News for You to a Radio 4 show called The Unbelievable Truth that's not a million miles from this.

This is the one where he and Lee Mack are team captains and Angus Deayton is chairman. The contestants have to bluff their way through various tales while their opponents work out which are true. So, for instance, did Gabby Logan really once steal red liquorice from Madonna's dressing room? Under close questioning from Rob Brydon it looks less and less likely. And is the mystery guest really Logan's former gymnastics rival, Mack's swimming teacher or, in fact, Robert Webb's ex-girlfriend?

Brydon and Mitchell make a great pair and what could be a stilted format is saved by some brilliant interplay and Brydon's flights of fancy.

The idea of two people meeting, falling in love and getting married isn't a theme we don't know inside out but this works thanks to wonderful writing and a cast of highly talented people who seem to fit perfectly in their roles. Rob Brydon's Bryn is wonderful and his love of James Blunt (the one about the wise man by the sea) really made me laugh.

Gavin & Stacey is completely believable and the writing is razor sharp. British comedy has taken a bit of a dip lately with the sketch show taking over but Gavin & Stacey proves the sitcom is alive and thriving.
