Came here to say the same thing. You would need to isolate the prongs so that you got flow through flesh, but even then it would likely do nothing more than a little jolt and flip the breaker. That being said, when I was a lad in school back in the stone age, one of the class idiots was fucking around and stuck a pair of tweezers in a desk outlet in science class and managed to burn his finger and thumb quite good before the breaker kicked off. Those fuckers were red hot instantly. This was before the days of GFCI and such, of course.
