Penn & Teller: Bullshit!

Season 6 premiere. The duo examines the "war on porn," a crusade by various special interest groups to restrict free speech and regulate the Internet.

Penn and Teller take a skeptical look at New Age medicine and its outrageous, unsupported claims of healing despite a heap of evidence that it doesn't work.

A closer look at the National Aeronautics and Space Administration, a government agency that spends scads of taxpayer money to achieve what private industry might be able to do more profitably and efficiently.

The cultural mumbo jumbo regarding dolphins is exposed, including New Age-style beliefs about the animals' evolutionary superiority and the nonsense about dolphin "energy" believed by many.

The magicians think twice about the high cost of getting a good night's sleep due to the ever-growing industry of sleep product hawkers trying to convince consumers that a special pillow, mist machine or pill will deliver a magical rest.

Penn and Teller consider the popularity of the "green" movement, a largely hypocritical philosophy linking sanctimonious politics to an "ethical" lifestyle while doing little or nothing to actually create a healthier ecosystem.

The mind control courses known as sensitivity training are dissected and their roots in political correctness, an increasingly litigious culture, and the suffocation of free speech, are finally exposed.

The contrary hosts argue that the world's never been safer for children, but you'd never know it in our culture of fear, toxic toys and even anti-anxiety medication for kids.

Penn and Teller argue that the notion of "world peace" is a utopian ideal that is dangerously naive and completely out of sync with human nature.

In the Season Six finale, the merry myth-shatterers puncture the nostalgic but unrealistic tendency of humans to long for an idyllic past - one that, in truth, never really existed.
