Magicians and Illusionists Penn and Teller have a popular TV show on the Showtime channel called, ahem, “Bullshit”. In homage to their debunking mentor, James Randi, they take on a number of subjects they feel could use a little “clarity”.
They recently (last Thursday night) took on Al Gore and carbon credits. The entire 30 minute show is available via the website VREEL (update You Tube has it now, VREEL started installing Zango a couple of days ago – a spyware)
Warning: more than a few obscenities are uttered in the show, but mostly for comic effect.
