1/2. Griff Rhys Jones , Dara O'Briain , Rory McGrath and a nervous dog called Loli set out in a wooden skiff. Launching in Kingston, Surrey, they retrace a journey up the Thames immortalised by Jerome K Jerome in his comic tale Three Men in a Boat. Along the way they drop in on David Gilmour of Pink Floyd and Antony Worrall Thompson. However, halfway to Oxford, Rory and Dara are in the pub while Griff is left to prepare supper. Will the two come back? Find out on Thursday at 9pm. Contains strong language. Director Michael Massey ; Producer Charlotte Wyatt In the swim: page 20; Moment of the week: page 57
