Egon describes the danger of keeping all of the captured ghosts within the containment unit and compares the amount of psychokinetic energy to a Twinkie... a Twinkie 35ft long weighing approximately 600 pounds... Trivia: Harold Ramis really had no intention of starring in the film, only writing it. But he decided to star in this film as Dr. Egon Spengler after he felt he was the best person suited for the role.
