huh?? there is no "weird guy" on ghost hunters that acts like that...... no one gets "possessed". I think you are thinking of most haunted with those annoying british people. *edit* oops sorry, I shouldve read all the replies on that page before I opened my mouth..... you were already corrected. my bad.
the difference between ghost hunters and the rest of these shows dealing with the paranormal (like most haunted) is that ghost hunters goes into a scenario with a mindset that its not a haunting..... they go there to debunk any particular "ghost haunting". they say about 80 percent of these are people's wild imaginations. they go in with thermal cameras, emf detectors, digital voice recorders, and of course cameras, in thoughts of capturing ghostly activity or an apparition. they are more scientific in their approach. Most haunted goes on feelings. they use overdramatic psychics, ouija boards, and table tipping to find ghostly activity....... things that are mostly absurd......
