- After Venkman meets with Dana, and he, Ray and Egon are sitting alone, eating Chinese take-out in the dark:
Venkman (lifting beer can in toast): To our first customer!
Ray (in unison): Our first customer!
Venkman: ... And only customer.
(beat as the trio take a swig)
Venkman: I'm gonna need to draw some of the petty cash. I should take her out to dinner, I don't want to lose her.
Ray: Uh, this magnificent feast here represents the last of the petty cash.
Venkman (silently, solemnly): Slow down. Chew your food.
- Venkman's introduction to Slimer.
"He slimed me."
"I feel so funky!"
Ray: (over the radio) "Venkman! I saw it! I saw it! I saw it!"
Venkman: (nervously) "It's right here, Ray. It's looking at me."
Ray: "He's an ugly little spud, isn't he?"
Venkman: "I think he can hear you."
- Want Funny Background Event taken to its hilarious zenith? Rewatch the prison scene again. As Egon is explaining Gozer and Zuul's plans, the prisoners that keep passing by become increasingly enthralled by the topic at hand!
Egon: ...Shandor decided that society was too sick to survive. [Pauses to glance at the other prisoners, then continues his info-dump.]
- The way Egon puts an end to Janine's flirting questions.
Egon: I collect spores, molds and fungus.
- Venkman teasing Egon shortly before going to confront the library ghost:
- The scene at the Mayor's office, when Ray explains how Obstructive Bureaucrat Walter Peck caused the ghosts to be released:
Ray: Everything was fine with our system until the power grid was shut off by Dickless here.
Peck: They caused an explosion!
Mayor: Is this true?
Venkman: Yes, it's true. This man has no dick.
Peck: [Being pulled out] I'll fix you Venkman, I'm gonna fix you...
Venkman: I'm gonna get you a nice fruit basket. I'm gonna miss him.
- On the commentary, Ivan Reitman relates meeting with William Atherton after the film became a hit, and he was quite upset that suddenly random people were calling him "dickless," including one incident where a whole bus full of tourists stopped to yell it at him.
- As Peck is being escorted out of the building, watch Ray. He puts his hands on his hips and puffs out his chest like a proud little bird with a smug smile on his face, seeing Peck shot down obviously making his day.
- When Ray, Egon, and Venkman are touring the old firehouse:
Spengler: I think this building should be condemned. There's serious metal fatigue in all the load-bearing members, the wiring is substandard, it's completely inadequate for our power needs, and the neighborhood is like a demilitarized zone.
Stantz: Hey, does this pole still work?? (slides down the pole) Wow. This place is great! When can we move in? You guys gotta try this pole! [...]
Venkman: (beat) I think we'll take it.
- Bill Murray's face when the Cardinal of New York walks in is quite possibly the greatest deadpan reaction gag of his career, and when you consider the range of said gags, that's saying something.
- The moment in the original when Ray decides that Bureaucratese is the best way to deal with an invading God from Dimension X:
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 cease any and all supernatural activity and return forthwith to your place of origin or to the nearest convenient parallel dimension.
Venkman: ... that oughta do it, thanks very much Ray.
- Followed up by some useful advice from the Christian Token Minority:
Winston: Ray, when someone asks you if you're a God, you say "YES"!
- Reportedly, Dan Aykroyd made an appearance at a convention where someone in the crowd asked him once again "Are you a god?" This time he did say "Yes."
- In the library, just before they find the ghostly librarian:
Stantz: Listen! Do you smell something?
- From the capturing of Slimer, we have the immortal couplet.
Stantz: I'm opening the trap - Don't look directly into the trap!
The trap is opened
Spengler: I looked at the trap, Ray!
- "The flowers are still standing!"
- "Guys, guys, we've been going about this all wrong. This Mr. Staypuft is okay, he's a sailor, he's in New York—we just get this guy laid, we won't have any trouble!"
- Peck being an ass again and Egon having had enough.
- Trying to fight Gozer.
Venkman: Whatever it is, it has to get by us!
Venkman: GO GET HER, RAY!
- This is an Ironic Echo of Ray saying "GET HER!" to the ghost in the New York Public Library in the beginning of the movie, which Venkman was amused by.
- After catching Slimer:
Ray: Sir, what you have there is what we refer to as a focused, non-terminal repeating phantasm, or a Class Five full roaming vapor. Real nasty one, too!
Peter: Now, let's talk seriously. For the entrapment, we're gonna have to ask you for four big ones. Four thousand dollars for that. But we are having a special this week on proton charging and storage of the beast, and that's only going to come to one thousand dollars, fortunately.
Hotel Manager: Five thousand dollars? I had no idea it would be so much. I won't pay it.
Peter: Well, that's all right. We can just put it right back in there.
Ray: We certainly can, Dr. Venkman.
Hotel Manager: No, no, no, no! All right!
- In the widescreen version, you can see Egon feeding Peter the numbers via hand signals.
- The conclusion of the Running Gag of Louis locking himself out of his apartment, with Rick Moranis' gloriously pathetic delivery of "Somebody let me iiIIIINNN!"
- Later, we get to see the party, culminating with Vinz Clortho in the back room getting a coat tossed in his face.
- The Central Park carriage-driver's reaction to the possessed Louis Tully talking to his horse, growling at him with inhuman red eyes, and running off screaming about how the apocalypse is at hand:
Carriage-driver: What an asshole.
- The conversation Vince had with the horse was funnier.
- Be glad the horse didn't turn out to be the Gatekeeper. Very glad.
- When Gozer is revealed as having taken on the form of the Stay-Puft Marshmallow Man. The look on his face is priceless, too - he looks so happy!◊
Peter: Ray has gone bye-bye, Egon. What've you got left?
- The Smash Cut moment when, having arrived at the Dana's building to battle Gozer and been greeted like conquering Big Damn Heroes by the people, we cut to see the Ghostbusters exhaustedly pulling themselves up the stairs to reach Dana's floor.
Peter: Where are we?
Ray: Looks like the mid-teens.
Peter: Well, when we get to twenty let me know. I'm gonna throw up.
- After Gozer is destroyed and the damage is done, the Ghostbusters all emerge from the rubble. Everyone's covered head to toe in marshmallow foam except for Venkman who's relatively clean. There's a moment where the guys are looking at Venkman like, "Wait, what the hell?"
- On a related note, it looks as if Dana was killed in the explosion. Ray, who had been making jokes about the smell of burned dog hair, realizes his mistake and apologizes with extreme sincerity and sympathy. Peter turns around to look at him... to see him standing there quite seriously, covered in marshmallow.
- The completely serious way Venkman responds to the "Twinkie" metaphor.
Winston: Tell him about the Twinkie.
Venkman: *dead serious* ...What about the Twinkie?
- When the boys are shooting at Gozer and Ray exclaims: "Aim for the flattop!"
- Winston applying to work for the Ghostbusters.
Janine (completely deadpan): Do you believe in UFOs, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster and the theory of Atlantis?
Winston: Ah... if there's a steady paycheck in it, I'll believe anything you say.
- When the police arrive at Ghostbuster HQ, Janine greets them with this priceless line;
Janine: Dropping off or picking up?
- Also her line during another endless day in the office:
Janine: I've quit better jobs than this. (Answers the phone.) Ghostbusters, whaddaya want?!
- The entirety of their first case snagging Slimer is one long CMoF the second they reach the elevators.
Elderly Gent: What are you supposed to be, some kind of a cosmonaut?
Venkman: Hah! No, we're exterminators. Someone saw a cockroach up on 12.
Elderly Gent: That's gotta be some cockroach.
Venkman: (deadpan) Bite your head off, man.
(the elevator opens)
Stantz: Going up?
Elderly Gent: I'll take the next one.
- Peter going to Dana's apartment to find she's been possessed by the a demon, Zuul, "the gate keeper".
Zuul:(opens the door) Are you the key-master?
Peter: Not that I know of.
(Zuul rolls her eyes and slams the door. Peter knocks again.)
Zuul: Are you the key-master?
Peter: Yes! (Zuul lets him into the apartment.)
- After she informs him of the coming of Gozer...
Peter: *deadpan* Are we still going out?
Zuul: "Do you want this body?"
) "Is this a trick question?"
- When he's in Dana's apartment for the first time:
Peter: I'm gonna go for broke... I am madly in love with you.
Dana: I don't believe this. Will you PLEASE get out?
Peter: And then she threw me out of her life.
- Any scene with Egon and Janine is either this or a Crowning Moment of Heartwarming.
- The scene where Egon rolls his eyes and awkwardly hugs Janine apparently went a little differently in the original script:
Janine: (worried) Egon, there's something very strange about that man. (she indicates Louis)I'm very psychic usually and right now I have this terrible feeling that something awful is going to happen to you. I'm afraid you're going to die.
Egon: Die in what sense?
Janine: In the physical sense.
Egon: I don't care. I see us as tiny parts of a vast organism, like two bacteria living on a rotting speck of dust floating in an infinite void.
She hugs him, Spengler responds awkwardly, not sure where to put his hands.
Egon: (nervous) You have nice clavicles. (he gulps) I wonder where Stantz is. I think we're going to need him.
- "Take me now, subcreature."
- "Egon, I'm a little fuzzy on the whole good/bad thing."
"Right. That's bad.
Okay, all right. Important safety tip, thanks Egon.
- Gozer gives the Ghostbusters a choice of who would destroy their home. Venkman tells Stantz, Egon, and Zedd to not think of anything, which leads to this:
Venkman: Nobody choosed anything! *Motions over to Egon* Did you choose anything?!
Venkman: *Motions to Zedd* Did you?!
Zedd: My mind is totally blank!
Venkman: I didn't choose anything!
*Egon, Venkman, and Zedd all turn towards Stantz and begin to close in on him.*
Stantz: I couldn't help it! It just popped in there!
Venkman: What? WHAT just "popped in there"?
Stantz: I-I tried to think!
- After it turns out Tully and Dana are alive, they pull them out of the husks of their dog forms.
Tully: [Looks at the wrecked roof] Man, the superintendent's gonna be pissed.
- The very last line of the Director's Commentary.
Joe Medjuck: (pointing at a credit) I had a secretary?!
- While the sequel is considered slightly inferior to the original, it does have this:
Venkman: Say, Johnny, where the hell are you from?
Janosz: Uh, de Upper Vest Side...
- Also from the sequel, when the Ghostbusters were committed:
Ray: As I explained before, we think the spirit of a 17th century Moldavian tyrant is alive and well in a painting at the Manhattan Museum of Art.
Psychiatrist: Uh-huh, and are there any other paintings in the museum with bad spirits in them?
Egon: You're wasting valuable time. He's drawing strength from a psychomagnotheric slime flow that's been collecting under the city.
Psychiatrist: Yes, tell me about the slime.
Winston: It's very potent stuff. We made a toaster dance with it. And a bathtub tried to eat his friend's baby.
Psychiatrist: A bathtub?
Venkman: Don't look at me. I think these people are completely nuts.
- Again from the sequel, the entire scene where Egon and Ray show Peter and Winston the effects of the mood slime, especially the dancing toaster.
Ray: We sing to it, talk to it, say... supportive, nurturing things to it.
Venkman: You're not sleeping with it, are you Ray?
(Ray shakes his head; Egon hangs his head in embarrassment.)
Winston: It's always the quiet ones.
Venkman: You hound.
- Louis' very helpful defense during the court room scene.
Louis: 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.
- The judge's reaction is priceless.
- As is Egon's:
Egon: Very good, Louis. Short, but pointless.
- We can't forget Louis' intro:
Louis: This isn't my kind of thing. I mostly do taxes, some probate stuff. I got my law degree at night school.
That's OK Louis. We were arrested at night. [Face Desk
- The power-up sequence:
- Singing to the overprivileged nine-year-olds.
Ray and Winston: (singing) If there's something strange in the neighborhood, who you gonna call?
) He-Man! He-Man!...
Ray and Winston: (trailing off) And it don't look good...
- After the ghosts of the Scolari brothers are on the loose:
Judge Wexler: (grabbing Ray) You've gotta do something! Help me!
Ray: Don't talk to me, talk to my attorney.
Louis: And that's me! My clients are under a judicial mistrangement order! That blue thing I got from her! They could be exposing themselves!
Peter: And you don't want us exposing ourselves!
- Egon's initial reaction is pretty sweet, too:
Judge: You gotta do something!
Egon: Why don't you just tell them you don't believe in ghosts?
- After they've grabbed the prosecuting attorney:
Peter: You're next, bubbles.
- Plus, when the Scoleri Brothers appear, the first thing under Ray's mouth (As the 'Busters and Louis hide under their table) is an excited, "Wow!"
- Louis tells the story of Snow White in tax lingo.
- After Louis suits up and goes outside:
Louis: Boy, this thing is heavy...
- Later on, he goes to the museum via bus... while wearing full Ghosbusters gear...with Slimer as the driver.
- The discussion of Vigo's Rasputinian Death:
Ray: He was poisoned, stabbed, shot, hung, stretched, disemboweled, drawn and quartered.
- Our peek into Egon's childhood: "We had part of a Slinky, but I straightened it."
- Janosz's line after being hosed. "Vy am I drippings vith goo?"
- At the end of Pete, Ray, and Egon's fight with the Scoleri Brothers. When they activate the trap while heroic music is playing in the background, the way the music ended with the skinny brother getting sucked in with his glowing eyes bulging out wide before the trap's lid quickly shuts closed made it look like a funny cartoon sequence ending with funny cartoon music.
- Janine's one-sided phone conversations when business starts picking up: "I'm sorry, but they can't get to you until after the new year... Well then just don't go in there!"
- "Ray... we'd like to shoot the monster. Could you move, please?"
- And the fact that their immediate reaction to Ray being possessed is to immediately hose him down.
- Vigo doing his Badass Boast on New Year's Eve - and Janosz being bored out of his skull.
- Janosz tries to convince Dana that Vigo's possessing Oscar is a good thing.
Janosz: There are many perks to being the mother of a living god...
- Ray attempts to be diplomatic to the Mayor of New York.
Ray: And I'd like to say that almost fifty percent of us voted for you in the last election.
- Egon's insults to the slime sample during his and Ray's demonstration to Peter and Winston.
You're nothing but an unstable short-chain molecule!
You have a WEAK electro-chemical bond!
- Made even funnier as the slime bubbles. No insult is too complicated for it to understand.
- How Egon describes how Peter's been since the first movie.
He was borderline for a while, then he crossed the border.
- A doorman, played by Bobby Brown asks Egon and Ray if they had an extra Proton Pack for his little brother.
Egon: The Proton Pack is not a toy.
Ray: He's probably right.
- Peter's speech to Vigo:
Venkman: Not so fast, Vigo! Hey, Vigo! Yeah, you. The bimbo with the baby. Anybody tell you the big shoulder look is out? You know, I have met some dumb blondes in my life, but you take the taco, pal! Only a *Carpathian* would come back to life now and choose New York! Tasty pick, bonehead! If you had brain one in that HUGE melon on top of your neck, you would be living the sweet life out in Southern California's beautiful San Fernando Valley!
- Deleted scene while in the Statue of Liberty:
Ray: We’ll stay to the right of the channel, go ashore at battery, go up the westside highway to 57th fly up 9 across the park at 65.
Peter: What?! No, no, no, no… you want to go up FDR to 4-2, slide over to 5 and jump up 5.
Ray: Up 5? We can’t go up 5! It’s one-way going the wrong way!
Peter: Ray, we’re walking a 150 foot national monument through Manhattan. You think we should worry about a traffic ticket?
