Venkman: This city is headed for a disaster of biblical proportions.
Mayor: What do you mean, "biblical"?
Ray: What he means is Old Testament, Mr. Mayor, real wrath of God type stuff.
Ray: Fire and brimstone coming down from the skies! Rivers and seas boiling!
Egon: Forty years of darkness! Earthquakes, volcanoes...
Winston: The dead rising from the grave!
Venkman: Human sacrifice, dogs and cats living together... mass hysteria!
Mayor: All right, all right! I get the point! What if you're wrong?
Venkman: If were wrong, then nothing happens! We go to jail, peacefully, quietly... We'll enjoy it! But if we're right, and we can stop this thing... Lenny: you will have saved the lives... of millions... of registered voters.
Peck: Please do not tell you are seriously considering listening to this man.
Mayor: (gestures at Peck after a beat) ...Get him out of here.
Egon: I have a radical idea. The door swings both ways, we could reverse the particle flow through the gate.
Egon: *beat* We'll cross the streams.
Venkman: 'Scuse me Egon? You said crossing the streams was bad!
Ray: Cross the streams...
Venkman: You're gonna endanger us, you're gonna endanger our client - the nice lady, who paid us in advance, before she became a dog...
Egon: Not necessarily. There's definitely a very slim chance we'll survive.
(beat while they consider this)
Venkman:(slaps Ray) I love this plan! I'm excited to be a part of it! LET'S DO IT!
Winston: This job is definitely not worth eleven-five a year!
Prosecutor: I'll ask you again, Dr. Venkman, why were you digging the hole? And please remember you're under oath.
Peter: There are some things in this world that go way beyond human understanding. Things that cannot be explained. Things that some don't even want to know about! That is where we come in.
Prosecutor: So what you're saying is that the world of the supernatural is your exclusive province?
Peter: Kitten, I think that what I'm saying is that: sometimes, shit happens, someone has to deal with it, and who you gonna call?
Louis Tully: Your Honor, ladies and gentleman of the-of the audience, I don't think it's fair to call my clients frauds. Sure, the blackout was a big problem for everybody. I was trapped in an elevator for two hours and I had to make the whole time. But I don't blame them. Because one time, I turned into a dog and they helped me. Thank you.
