Penn & Teller: Bull! (2003) : 3x10

It's scary to know in today's Age of Enlightenment, the world's fascination with the "paranormal" is at an all-time high. And where there are gullible believers, you can bet there are hordes of "experts" lurking, ready to sell something to them. We will delve into the realm of the "spirits" and take a look at the revived interest ghost hunting. We'll spend time with so-called parapsychologists as they track ghosts with their new-fangled, pseudoscientific equipment. Will they find something? Yeah, right! We'll show you how some of them bullshit themselves as much as their clients as they try to get to the bottom of nonexistent mysteries.
