I confess I've written more than my fair share of posts complaining about the never-ending march of paranormal, ghost busting shows haunting TV these days. You know the shows I refer to -- the "documentaries" promising to prove the existence of ghosts without ever finding anything resembling actual proof.

Every time I've written something bemoaning the arrival of another such show, I think it has to be over soon. There can't be another hour of clods stumbling around in night vision and reacting to sights and sounds the audience doesn't get to experience.

But, they keep coming. They keep finding nothing. But, evidently, people keep watching them. Now, we have Ghost Intervention -- running through December. The 4-part docu-series from TLC "chronicles a case manager and a team of women with psychic abilities as they try to help different families who are struggling with paranormal activity in their homes."

There was a time when ghosts, apparitions and other paranormal entities led a quiet, under-the-radar sort of un-life. Now, thanks to the proliferation of reality or documentary-style TV shows devoted to the subject, the poor dead have nowhere to hide.

These days everybody wants to talk about their brush with the inexplicable, and it seems there are more paranormal investigators than actual ghosts stumbling around in the dark. How believable are these shows? Let's see.

If a show like Top Chef never found a meal, would you watch it? If Ice Road Truckers couldn't find snow, would you pay attention?

Yet, every week, paranormal investigation shows like Ghost Hunters or Paranormal State hit the air and unveil the whole pile of absolute squat they found. Now, there's a new contender in the "Hey! Look! We found pretty much nothing!" category with the Discovery Channel's Ghost Lab.

Each week two thick slabs of Texas beef named Brad and Barry Klinge (right) take their Everyday Paranormal investigation team out into the wild haunted yonder. They come armed with their traveling "ghost lab" -- a 24-foot car hauler "capable of providing 200,000 watts of electricity to power audio, video and photo analysis stations; flat-screen televisions and an interactive touch-screen smartboard."
