Sorry but I think that these guys are faking this. I would need more proof than a video like this to believe this. It's not just about the body's ability to tolerate the electric current - in some of these cases, there should be enough voltage drop to cause burns. What the Serbian guy does is more believable. If your skin is very dry you could do the majority of what he does (not entirely safely but ...). When he holds the conductors in his mouth, he could be well enough insulated from ground - he is not conducting THROUGH his body to make the circuit like the Indian man appears to be doing.
