Though it shouldn't surprise me, I just didn't realize there were seriously professional ghost busters out there. Until I took a gander at this ridiculous Gauss Master Ghost Detector. Yup, that's right, you too can join in the fun of following Bill Murray's pretend footsteps by measuring ghost EMF's to find your neighborhood ghouls. And it even comes with instructions for "conducting paranormal investigations." Uh huh. On the plus side, it's only $29.95 on eBay.
