- Dr. Egon Spengler: [using walkie talkie] I believe they enable him to create the rings by manipulating waves of ecto-charged green visible light.
- Kylie Griffin: Are you sayin', that if we send out proton streams a half cycle out of phase with his light waves, the two will cancel each other out, shutting off his powers?
- Dr. Egon Spengler: I... suppose I was.
- Eduardo Rivera: I don't believe it, you're starting to talk just like Egon!
- Eduardo Rivera: It's a particle.
- Kylie Griffin: It's a wave.
- Eduardo Rivera: Particle.
- Kylie Griffin: Wave.
- Eduardo Rivera: The cute little light particles...
- [grabs a spoon from Garrett]
- Eduardo Rivera: ... bounce like tiny tennis balls off reflective surfaces. And when the surface ain't flat, they get seriously messed up.
- Kylie Griffin: Look, brainiac. Light passes through the glass and gets bent on different bandwidths creating different colors. Can tennis balls do that? Not particles. Waves.
- Garrett Miller: Ahh, I recognize that fragrance. Physics 101.
- Roland Jackson: Actually, you're both right. Planck's quantum theory stipulates that waves of light sometimes act like particles. While Heisenbergs's uncertainly principle postulates that particles of light or photons display wave-like patterns.
- Garrett Miller: Shooting spitballs at boulders, Roland my friend. Never gonna penetrate.
- Eduardo Rivera: Yeah, like you get it.
- Garrett Miller: Of course, I do. Planck's quantum theory, uh... st... stipulates... uh... uh... what he said.
- Roland Jackson: Look, guys. It's simple. Light is 'both' a particle 'and' a wave.
- Janine Melnitz: It's like that stuff that's both a gum and a candy.
- [phone rings]
- Janine Melnitz: Ghostbusters, now offering physics tutoring at reasonable rates. Suit up, guys.
- Roland Jackson: Gu Mo's powers have nowhere to go. He's on overload.
- Eduardo Rivera: Yeah, without an outlet, the photons are building up like a grenade with the pin pulled out. If we shut off our blasters...
- Kylie Griffin: [interrupting] Now who's talking like Egon?
- Roland Jackson: Eduardo's right.
- Garrett Miller: He is?
- Eduardo Rivera: I am?
- Roland Jackson: Everybody, power down, now!
- Dr. Egon Spengler: Removing the Dragon's Eyes must have released him. If Gu Mo regains those gems...
- Janine Melnitz: [interrupting] He'll create fifteen flaming circles here, making him unstoppable.
- [Egon looks at her with surprise]
- Janine Melnitz: You work here long enough, you pick up a few things...
