The other day, a show in Australia called "Studio 10" had a guest who claims he can read people's minds by listening their voice.
So he did a stunt called "nail gun roulette", where he had a co-host named Sarah Harris randomly put four different nail guns on a rack . . . one of which was loaded.
Then he asked her questions about each one while he was blindfolded, and started eliminating the ones that DIDN'T have nails in them. Each time he eliminated one, he had her hold it up to his hand, his arm, or his stomach, and pull the trigger.
Anyway, he pulled it off WITHOUT getting hurt. But the highlight was the first gun. Because when Sarah picked it up to shoot it, she held it BACKWARDS, and almost shot herself in the FACE. It wasn't loaded, but no one knew that.
