Holy shit, this guy is scary. I have absolutely no doubt that he is quite possibly the single greatest entertainer/showman/bizarre-mind-stealing-genius ever. I'm watching the second episode of his new "Experiments" series and it is fantastic. In the first episode he convinced somebody to commit an assassination through hypnosis and suggestion. He is, by far, the best thing on TV. Brits can watch pretty much his entire back catalogue here:
Americans/Australians/anybody else should go out of your way to find some of his work online. I recommend starting with Heist.
