Stage hypnotist Doug MacCraw

I'm skeptical but open-minded about most things, but when it came to hypnotism I was mostly skeptical. I figured it could have minor effects, but that anyone hypnotized could quickly break out of it. I got back from a vacation a couple weeks ago, and there was a "stage hypnotism" show by Doug MacCraw. You can see a bit of what it was like in this Youtube video. I also found an interview with Doug over at The Daily Orange. He says he "bores people into hypnosis". However he does it, I'd like to learn. He mentioned at the end that the medical applications of hypnosis are underrated, which, if that show is any indication, seems likely.
