The blanket critical disdain heaped upon Brendan O'Carroll's Irish matriarch can feel a little lazy. So, to bend over backwards, this format, in which guests subject themselves to Agnes's lewd provocations, is the character's best delivery mechanism. Tonight, Amir Khan, Danny Dyer and Kate Humble pay a visit.

Tonight, Harry uses the visit of Kate Humble as the pretext for a wildlife special, complete with his own version of the Springwatch-patented badgercam. Expect a few highlights from Humble's career (with particular emphasis on bizarre Sky outing Wild Things), all presented with Hill's customary safari-suited glee.

"This is a horrible stupid game!" moans David Mitchell towards the end of tonight's episode. "Whatever we say, if we get it wrong, we'll look like we've believed something ridiculous." Yes, that's the general drift: anecdotes and personal habits so far-fetched we refuse to believe they're true, though some must be.

Did Richard Madeley really wake up naked in a cupboard one Christmas morning, holding two cans of spray snow? Do pigeons nest using clippings from Kate Humble's hair? As the controversies rage, they're all leading up to the priceless sparring between Mitchell and rival captain Lee Mack. This week's battleground: pens.
