Following on from a one-off in January, Jimmy Carr returns to asks questions on art, literature, television, music, geography, politics, science and celebrity from the last 100,000 years of human history. This episode see Jonathan Ross, Mel Giedroyc, Kristen Schaal, David Mitchell, Bob Mortimer and Claudia Winkleman battling it out, with First Dates' Fred Sirieix popping in for a swig of champagne and Strictly Come Dancing's Karen and Kevin Clifton giving the panelists a much-needed dance lesson. Oh and of course, an appearance by Channel 4's Jon Snow, as is tradition at this stage.
