Detoxing Penn & Teller: Bullshit! : Season 5 Episode 4

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.
