Mayor: What do you mean "biblical"?
Dr. Raymond Stantz: What he means is Old Testament, Mr. Mayor. Real wrath of God type stuff! Fire and brimstone coming down from the skies! Rivers and seas boiling!
Dr. Egon Spengler: Forty years of darkness, earthquakes, and volcano's!
Winston Zeddemore: The dead rising from the grave!
Dr. Peter Venkman: Human sacrifices, dogs and cats living together! Mass hysteria!
Thats right! You can panic now.
