Hyponotism is really quite easy to do. The key ingredients are alcohol and a willing subject. The hooch lowers the defenses of the participant and makes them far more agreeable to engage in acts or talk which they otherwise would be loath to do, hence why many guys ply chicks with booze to get into their tight little pants.
Second, the follower type of individual is much, much easier to get to go under than someone strong willed or independent. For instance, I tried to let myself be hyponotised, but the farthest I could get was at the point where I got tunnel vision. A part of me refused to give up control to another and wouldn't allow me to relinguish that final bit of self authority. It is this, I believe, which makes makes women easier to hypnotise than men. Women, by culture, are expected to take subordinate roles, thus give control to others. Argue with all you wish, but my experiences show this to be true.
Once the subject is inebriated, get a light (not a candle) for them to focus on and dim all other lights in the room. Have the observers be silent since laughter or noises distract the participant. Explain to the person that you are going to count to 100, and by 25 they are going to be very relaxed. By 50 they will be extremely tired, and by 75 they will be asleep. Make certain you modulate your voice so that it is low, slow, and somewhat intimate, as if you were telling them a secret. They are to look at the light and not attempt to see anything else. Place yourself behind them and by their ear so that you become a disembodied voice.
You will know immediately that they are in a hyponotic state when their eyes close and their breathing deepens. At this point, explain that at the count of three they will obey your commands, but no harm will come to them.
It's at this time you pretty much have run of the mill and can do anything, so long as it does not exceed a physical ability or moral threshhold. Consider anything a drunk might do is what your hypnotised person will be willing to do.
Post hypnotic suggestions are given by saying things like, "When you hear the word 'rooster' you will have an unstoppable urge to crow," or the like. I have found that these are effective to up to two days post-hypnosis.
Finally, you can clear the subject's memory of the events by simply telling them they will forget everything upon waking up. Or not. You can just as easily have them remember everything. Then you tell them at the count of three they will wake up.
Like I said, it's simple.
