It's no secret I'm no fan of paranormal investigation shows, shows like "Ghost Adventures" or "The Dead Files." I mean, if ghosts are real, mathematically there would eventually be a haunted Walmart. Seeing them try to do an investigation in a haunted Walmart would be hilarious, given they stay open 24/7 364 days a year. I mean, if ghosts are real and could be potentially anywhere, why can't there be a ghost haunting a slurpee machine in a 7-11, in which case why don't they have investigators checking out reports of said specters possessing the slurpee machine at 7-11? I think this could be big old house and museum covering up the truth. Your Whole Foods could be owned and operated by... POLTERGEISTS!!
But the more likely possibility is that ghosts, if real, would better things to do than to mess with whomever Zak Bagans sends to do the work he doesn't want to do.
