I have always been interested in paranormal investigation, and I feel that the SciFi series "Ghost Hunters" is, to the common man, what Hans Holzer is to the upper crust. (And I do like reading Hans's literary exploits in the paranormal, as well ;-) ).
Furthermore, I feel that Ghost Hunters has a little more down-to-earth approach that more people can identify with. It's fresh, in-your-face, and they don't pull any punches, at least none that I can see.
I present then, some clips from the youtube.com site from Ghost Hunters.
