The Real Ghost Busters1986

[after a magic book zooms down a pit, as part of Vladimir's ceremony to summon an "Old One"]

Vladimir:

Dr. Peter Venkman:
Excuse me, but did it occur to you that your best weapon against us was that book, and that now it's down there, and you, you're pretty much up here?

Vladimir:
...Good point.
