Ray Stantz: Where do these stairs go?
Peter Venkman: They go up.
Peter Venkman: Get her?! That was your plan? Get her?!
Ray Stantz: Everything was fine with our system until the power grid was shut off by dickless here.
Walter Peck: They caused an explosion!
Mayor: Is this true?
Peter Venkman: Yes, it's true. This man has no dick.
Ray Stantz: You know, it's just occurred to me, we really haven't had a completely successful test of this equipment.
Egon Spengler: I blame myself.
Peter Venkman: So do I.
Ray Stantz: Well, no sense in worrying about it now.
Peter Venkman: Why worry? Each of us is wearing an unlicensed nuclear accelerator on his back.
Peter Venkman: Or, you can believe Mr. Pecker.
Walter Peck: My name is Peck.
Peter Venkman: Human sacrifice, dogs and cats living together! Mass hysteria!
Ray Stantz: We should split up.
Peter Venkman: Good idea. We can do more damage that way.
Dana: You don't act like a scientist.
Peter Venkman: Most of them are pretty stiff.
Dana: You're more like a game show host.
Peter Venkman: We came, we saw, we kicked its ass!
Peter: Go get 'er Ray!
[Ray hesitates.]
Ray: Gozer, the Gozerian, good evening. As a duly designated representative of the city, county and state of New York, I hereby order you to return forthwith to your place of origin or to the nearest convenient parallel dimension.
Peter: That oughta do it, thanks very much Ray!
Peter Venkman: Oh my god. Look at all the junk food!
Janine Melnitz: Do you want some coffee, Mr. Tully?
Lewis Tully: Do I?
Egon Spengler: Yes, have some.
Lewis Tully: Yes, have some!
Winston: I gotta tell you, these things are real. Since I've joined these men, I have seen shit that'll turn you white!
Peter Venkman: I get it! Oh! Very cute. Whatever we think of. If we think of J. Edgar Hoover, J. Edgar Hoover's gonna appear and destroy us.
Egon: And he wasn't alone. He had close to a thousand followers when he died. They conducted rituals up on the roof. Bizarre rituals that intended to bring about the end of the world now it looks like it may actually happen!
Peter Venkman: I'm gonna go for broke. I am madly in love with you.
Dana: I don't believe this. Would you please leave?
Peter Venkman: And then she threw me out of her life. She thought I was creep. She thought I was a geek, and she probably wasn't the first.
Dana Barrett: Are you the key master?
Peter Venkman: Not that I know of.
[Dana slams the door. Peter tries to look through the eyehole. He knocks on the door and she opens it.] Dana Barrett: Are you the key master?
Peter Venkman: Yes.
Ray: It's my fault.
Peter: It's OK. The table broke the fall.
Peter Venkman: We've been going about this whole thing all wrong. This Mr. Stay Puft is OK. He's a sailor. He's in New York. We get this guy laid, we won't have any trouble.
Peter Venkman: Let's show this prehistoric bitch how we do things downtown.
