In episode 610, the sixth season 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.

Penn and Teller explain the necessity of nuclear power in modern society, advocating that it is both cleaner and safer than the alternatives such as coal.

They say Maui's the place to achieve a cosmic orgasm while holding a tantric pretzel pose. Watch out! It's a flying vortex!

Mount Rushmore is usually seen as a symbol of American pride and ingenuity. In an episode that will have American patriots enraged, Penn and Teller interview a native tribesman who sees the monument as a symbol of American sacrilege and imperialism, while Penn and Teller themselves say it is little more than an elaborate tourist trap envisioned by a white supremacist.

In episode 605, 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.

We'll go to a hearing in NYC, where the dangers of second-hand smoke, and legislating human behavior, is being hotly debated and stage a hidden-camera sting that shows just how rabid people are about this topic. Also, a look at smart videos, teaching babies to read, the "Baby Whisperer," and the baby product industry that preys on guilt ridden parents with money to burn.

This show checks out penis and breast enlargement products, techniques and myths. Also aphrodisiacs: do they work? Expect some graphic and jaw-dropping visuals.

There's a hysteria in America. A hysteria about what's become known as "the traditional family" and the desperate urgency to "save" it. And this rallying cry is not just coming from right wing conservatives and religious groups in the Red States (although, they're doing their share of tub-thumping.) The media (advertisers) and the government also have a vested interest in perpetuating the traditional concept of family: mother, father, two kids, dog and picket fence. But this hysteria is ignoring a key fact, the "traditional family" is bullshit. The traditional family structure may be for some, but it isn't for everyone. Shouldn't we stop trying to jam square pegs into round holes? Isn't it time for "Bullshit" to redefine the definition of "family?"

Has our surveillance society made our lives more convenient? Has it succeeded in deterring crime and terrorism? Are the watchers just a bunch of incompetents as prone to distraction as the two bit rent-a-cop security guards at your neighborhood mall? Have the freedoms guaranteed us by the Constitution become just another load of Bullshit? In this episode, we'll watch the watchers and discover what role human nature plays in data mining and surveillance. We'll unveil the latest, and scariest, technologies and prove just how easy it is to get the goods on anyone - even you. Security? Freedom? There's bullshit on all sides!

Penn & Teller expose the truth behind our supposedly toxic insides. We find out about "colonics" and those "cleansing" diets including today's diet darling, the "Neera Super Cleanse." An actual Parasitologist - a scientist who studies parasites - tells us the truth about the parasites among and within us. A visit to the world's largest inflatable walk-through colon rounds out the episode.

Penn and Teller visit Congress to discuss the bullshit which is America's complex, unfair tax system.

In the Season Eight premiere, it's as all-American as apple pie, but cheerleading is also responsible for 65% of all catastrophic female sport injuries, with competitive coaches, fanatic parents, and a multimillion dollar industry concerned with its bottom line.

PETA (People for the Ethical Treatment of Animals) is against all forms of medical testing involving animals - regardless of the potential benefits to human beings. PETA supports banning the ownership of pets and advocates releasing them into the wild. It's enough to make a vegetarian eat meat!

Penn & Teller examine the organic food industry to determine if it is, in fact, more nutritious, and better for the environment.

According to Penn and Teller, America's seniors are stripped of their dignity thanks to ongoing stereotypes about old people. They investigate the widespread beliefs that old people can't drive, don't have sex, and smell bad.

BULLSHIT tours Inverness, Scotland, the home of the Loch Ness Monster, with two "cryptozoologists" who try to lure the mythical giant of the deep to the surface... with a bag of fish guts. Later, we investigate the latest mysterious Bigfoot footage posted on the internet. In between, we check in with some credentialed scientists for their take on the bullshit "science" of Cryptozoology. Will our scientific experts conclusively debunk the existence of mythical creatures? Here's a hint: Crypto means "hidden" while zoology stands for the study of animals. Put them together and what do you get? BULLSHIT!

Penn & Teller look at women's breasts and society's response to them. In New York City, we meet a young mother who inadvertently tested corporate tolerance for breast-feeding in public. Further south, in Daytona Beach, Florida, we meet a woman who challenged the rights to flash her breasts in public. We also meet a breast cancer survivor who is not a supporter of those ubiquitous Pink Ribbons. And, down in the valley of porn, we find a topless porn star/mother of two who philosophizes on the benefits of the La Leche League.

The world will end on December 21, 2012 - that's according to a growing legion of doomsayers who follow the primitive Mayan calendar. The duo follows a pair of investigators to ancient Mexico to explore the mysterious "Mayan Prophecy".

Finally, an episode that will make every man feel regret, cringe with pain, and grab their genitals. What would make the male sex react like this? Two words - snip and chuck. If this alone doesn't make you cringe then this will: when your foreskin was removed thirty percent of your sexual pleasure went with that little piece of skin. Ouch! We'll examine the historical, religious, medical and ethical arguments associated with circumcision. And we'll have a little hidden-camera fun with the topic, as well. After all we are talking about dick!

Everyone knows that prostitution is practiced throughout the land. Where it is legal - in only a few Nevada counties, prostitution is vigorously regulated and monitored by the State of Nevada Health Department. The women submit to compulsory medical tests for STDs. No one is forced to work as a prostitute. Pimps don't exist. HIV has never been detected. The women earn regular paychecks and tips. Some even get vacation and sick days. And they pay taxes! It's BULLSHIT that it's illegal for two consenting adults to have sex with each other!

BULLSHIT goes on the prowl for virgins! We meet women - and men! - who are saving themselves for marriage. We find out -what the hell for? Then, there's sex education! We find out if it is helping them screw…or screwing them up. And we get really revved up about teaching abstinence only! We meet an expert who encourages multiple sex partners before settling down. He has proof that sex reduces stress and it releases endorphins that make us feel good. The cherry on the top of our cherry is a visit to a masturbation clinic. Now we're talking sex education! We'll also meet up with the former US Surgeon General, Dr. Jocelyn Elders. She was fired for advocating masturbation as an alternative to sexual intercourse to prevent STDS, and that's BULLSHIT.

In the sixth season premiere, Penn and Teller look at the "War on Porn",a crusade by various special interest groups to restrict free speech and regulate the Internet.
