Lee Mack presents Duck Quacks Don't Echo, the show that test-runs the world's most startling facts with three celebrity guests in each episode. Each episode is split into three rounds. First the celebrity guests present their facts and these are tested out. The other celebrities and Lee mark the celebrity on their fact. The second round see's the celebrities choose an audience members fact and a panel of verifiers prove whether the fact is correct or not. The verifier marks the second fact. The winner of the first two rounds then help Lee prove his fact for the week. Add to my shows
