How do you create a being shaky resembling within the movies?

I've seen surrounded by the movies that when a person hits the side of the collar of another person, he/she faint or falls asleep or something like that. also, within other movies, they sort of grab the shoulder or something similar to that. Is that real? and if so, how do you do it?How do you create a being shaky resembling within the movies?
Yeah it's genuine, but I highly recommend you DON'T do it. Don't forget within the movies...they're acting and not actually doing that. But none the smaller number on the shoulder in those little divits seperating your shoulder muscle from your collar bone, in attendance are A LOT of nerves in that nouns, and by pinching it just right you can transport the nerves into a state of panic, which sends the message to the brain to shut down the body as a saftey apparatus. So that's were the pinching and karate chopping comes surrounded by. If you do it wrong though, (e.x. pinch the nerves for too long) then you can permantly blight the person mentally and physically, and I hold heard of cases of inhabitants dying because of it. So yes it's true, but don't do it to a friend for a laugh, because you won't be laughing if you do it wrong.
