Crusading naturalist Chris Packham gets a rare chance to enjoy himself in another frolicsome edition of Hill's comedy panel show. Watch the nation's favourite grebe-fancier bag the battiest questions and pitch into a mud fight between the Krankies, Pam St Clement, Chelsee Healey and the host.

More shrieking goonery with the good doctor Hill. Literally popping up and dropping in this week are former Blue Peter host Konnie Huq, Lewis star Kevin Whately, and Corrie's Georgia Taylor and Bill Roache (who at one point will do something ghastly to a cuddly toy). Plus, cameos from Joe Fagin and a former home secretary.

"We're not doing points, this isn't The Chase!" Harry Hill's surreal spin on celebrity panel shows has always been more interested in cultivating an anything-goes atmosphere of inclusive absurdity than doing something as boring as keeping score. The third series kicks off with a particularly seasoned guest list as Martine McCutcheon, Les Dennis, Alison Hammond and Sir Tom Courtenay heroically send themselves up in service to Harry's daft skits and silly bits, including an unexpected tribute to Raiders of the Lost Ark.
