"I've had various girlfriends," hypnotist Rod Nodvik once recalled, "and I've hypnotized them so that when I winked, they'd go into full-blown orgasms. It's extremely useful."
[Nodvik also purported to produce a trance state called hyperempiria: "Let's say you're married and your wife has a thing for Brad Pitt. She could go into hyperempiria and, for a weekend, she'd think you were Brad Pitt!"]
