Jackson Booth-Millard It first started in Australia, then the USA made their own, and now we the British have our version. If you like the show improvisational comedy of Whose Line Is It Anyway?, then you'll love this programme. Hosted by Paul Merton, this basically takes four of Britain's best known comedy or acting talents, and places them into a situation they know absolutely nothing about. They are given a costume, and then they walk through the door, usually to the catchphrase "Thank God You're Here", and they have to improvise in this situation to make the audience laugh as much as possible. Merton also joins in, and they all join in at the end in a group scene, and the worthy person is given the show trophy. Guests on the show have included Ben Miller, Fern Britton, Hamish Blake, John Thomson, Clive Anderson, Sally Lindsay, Michael McIntyre, Marcus Brigstocke, Lee Mack, Jennie McAlpine, Phil Nichol, James Corden, Vernon Kay, Phil Nichol, Kirsten O'Brien, Rufus Hound, Richard Wilson, Claudia Winkleman and Steve Furst. Very good!
