Dr. Peter Venkman

— You know, you don't act like a scientist.
— They're usually pretty stiff.
— You're more like a game-show host.

Twenty-four hours a day, seven days a week. No job is too big. No fee is too big.

— Whatever it is, it's gotta get by us. Right. Go get her, Ray!
— Gozer the Gozerian? Good evening. As a duly designated representative of the city county and state of New York I order you to cease all supernatural activity and return to your place of origin or to the nearest convenient parallel dimension.
— That ought to do it. Thanks very much, Ray.

— But there are some things we do... standard procedures in a case like this, which often bring us results.
— I could check out the structural details in the building. Maybe the building has a history of psychic turbulence.
— Right. Good idea.
— I could search «Zuul» in the usual literature. Spates Catalog.
— I'll take Miss Barrett back to her apartment and check her out. I'll go check out Miss Barrett's apartment. O'kay?

— There's something very important. I forgot to tell you.
— What?
— Don't cross the streams.
— Why?
— It would be bad.
— I'm fuzzy on the whole good/bad thing. What do you mean, «bad»?
— Imagine all life as you know it stopping instantaneously and every molecule... in your body exploding at the speed of light.
— Total protonic reversal.
— Right, that's bad. Okay.

— What are you supposed to be, some kind of a cosmonaut?
— No, we're exterminators. Somebody saw a cockroach up on 12th.
— That's gotta be some cockroach.
— Bite your head off, man.

— You can't park that here!
— Everybody can relax, I found the car. Needs some suspension work and shocks... and brakes, brake pads, linings, steering box, transmission, rear end.

— Dana, did you see some shirts here in the floor-bed area?
— Yeah, I put them in the hamper.
— I have a hamper?!
— Yeah, it's in the bathroom.
— Neat. Will you tell me next time you're gonna do that, though, please?
— Well, I thought they were dirty.
— I have more than two grades of laundry, okay?
— There's not just clean and dirty. There are many subtle levels, okay?
— You hang this outside the window for 20 minutes, it's perfectly fine.
