David Mitchell hosts a new show where comedians test their survival skills, Kirstie Allsopp and Phil Spencer are back house hunting, and there's a curious documentary about a genius without a brain . . .

Pick of the Day

Outsiders, 10.00pm, Dave

This is a new comedy challenge show where six comedians camp in the woods for a week and face a multitude of challenges to test their outdoor survival skills.

If they can prove to host David Mitchell that they've got what it takes, then he'll reward them with a highly-coveted (no messing!) badge.

"Civilisation is clearly crumbling, so it's high time we worked out whether we can cope without it," says Mitchell.

"And if you can think of a better way of doing that than making six comedians learn survival skills, then you weren't involved in the development process of this programme."

Tonight, Mitchell oversees Toussaint Douglass, Ed Gamble, Kerry Godliman, Jessica Knappett, Jamali Maddix and Lou Sanders as they undertake outdoorsy tasks.
