I was reading a blog post here about that awful A&E show Paranormal State and it occurred to me:
Why do the EVP voices always say 'scary' ghosty things? How come they never say "Man, I could go for beer right about now!" or "I miss Twinkies!"?
Of course, considering how auditory pareidolia works, they're probably just mis-hearing what those crazy EVP spirits are really saying and in fact thay are saying things like "Could somebody please play the new Dylan CD?".
