Parapsychology...
Janine Melnitz: Do you believe in UFOs, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster and the theory of Atlantis?
Winston Zeddemore: Ah, if there's a steady paycheck in it, I'll believe anything you say.
Dr. Peter Venkman: Oh my God. Look at all the junk food.
Dana Barrett: No. No, Dammit. Look this wasn't here...
Dr. Peter Venkman: You actually eat this?
Dana Barrett: No, this wasn't here. There was nothing here. There was this... space, with a building or something with flames coming out of it, and there were creatures writhing around it, and they were growling and snarling. And there were flames, and I heard a voice say "Zuul" I mean it was right here.
Dr. Peter Venkman: Well I'm sorry, I'm just not getting any reading.
Dana Barrett: Well are you sure you're using that thing correctly?
Dr. Peter Venkman: Yeah, Its not... I mean I think so, but I'm sure there are no animals in there.
Dana Barrett: This is great. Either I have a monster in my kitchen or I'm completely crazy.
Dr. Peter Venkman: [s m i l e s] I don't think you're crazy.
