"What about the Twinkie?"
- Peter Venkman; Ghostbusters
Egon warned the other Ghostbusters that the level of psychokinetic energy (P.K.E.) in the city was unusually high, and something "big" was on the horizon. Winston asked him what "big" meant exactly, so Egon picked up a Twinkie from Ray's desk and used it for an analogy: whereas a normal Twinkie would represent a standard amount of P.K.E., the surge Egon was tracking would equate to a Twinkie that was thirty-five feet long and weighing approximately six hundred pounds. Ray was stunned, and Winston observed, "that's a big Twinkie." Egon then ate the Twinkie.
Later, Peter arrived and Winston asked Egon to "tell him about the Twinkie." Concerned, Peter asked, "what about the Twinkie?"
- Harold Ramis came up with the Twinkie analogy as part of a longer explanation describing the universe as an expanding, four-dimensional balloon. The Twinkie part was the only thing to survive into the movie.  
- In The Real Ghostbusters episode "Camping it Up", Twinkies were scripted to be in Slimer's bag at the start. 
- The dimensions of Egon’s twinkie are inconsistent: a 600-pound Twinkie should only be about 6.4 feet long while a 35-foot long Twinkie should weigh about 50 tons.

- ↑ Shay, Don (November 1985). Making Ghostbusters, p. 104 annotation. New York Zoetrope, New York NY USA, ISBN 0918432685. Harold Ramis says: "We were delighted with the notion that this script could be so 'out there,' and yet still have a scientific and parapsychological plausibility. From a physics point of view, Dan was always talking about things like 'holes in the reality envelope.' Well, I didn't know what that would mean to an audience, so I came up with this 'Mr. Wizard' kind of analogy -- describing the universe as an expanding, four-dimensional balloon. And as I was talking, I'd be blowing up this balloon. Then I'd explain, 'If something were to penetrate the envelope of our reality...' -- and the balloon would pop. That then led to the 'Twinkie' analogy. The whole thing made sense in terms of the plot but it was just much too long, so only the Twinkie survived."
