[Update: I received an email by Matt Thurling, the founder of Science.tv. I didn't realize originally that he created the video, and poking around that site is something I highly recommend!]
If you're a UK skeptic, you know Ben Goldacre: he writes for The Guardian and runs the Bad Science website where he debunks all kinds of quackery and nonsense. He spoke at TAM 6 last year, and will be one of our speakers at TAM London, too.
And now he's a movie star! Well, a video star. Here he is, concentrating (haha! Get it? Man, I kill me) on homeopathy.
