It at first seems silly to debunk something like vampires. Creatures that are, especially now, so a part of pop-culture that we actually have space vampires on TV.
But no, there are people who actually believe in these things! Ghosts are one thing. There are tons of people who believe in ghosts. They're no less idiotic, but at least the group is larger.
So some scientists have taken it upon themselves to disprove both ghosts and vampires. The vampire one is beyond reproach, but they don't seem to get the concept of "supernatural" for ghosts. They don't need feet to walk! They have GHOST FEET.
