Penn & Teller: Bull! (2003) : 4x9

They say numbers don't lie, but in the hands of the media, politicians, pollsters and salesmen, numbers can be downright subversive. BULLSHIT meets the author of Damned Lies and Statistics - he tells us how numbers are craftily manipulated based on political affiliation and agenda. The numerically ambiguous world of Vacation Time Shares leaves our undercover operative dazed and confused. We also take street cons to Las Vegas - a town built on Numbers - and reveal how readily most of us can be cheated. And we look into the bullshit behind political polls, gambling odds and state lotteries. Source: http://www.sho.com/site/ptbs/prevepisodes.do?episodeid=s4/numbers
