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?

The intrepid trio, Griff Rhys Jones, Rory McGrath and Dara O'Briain, plus dog, set off on the second leg of their journey up the Thames from Kingston to Oxford. Rowing into the middle of the Wallingford Regatta, Dara decides to enter them in a race. The junior novice ladies team turn out to be worthy opponents. As night draws in, there are still three miles to go before Oxford. Will the weary trio ask for a little help to speed them along?
