Dr. Peter Venkman: As a friend, I have to tell ya you've finally gone around the bend on this ghost business. You guys have been running your ass off, meetin' and greetin' every schizo in the five boroughs who says he has a paranormal experience. What have you seen?
Dr Ray Stantz: Of course you forget, Peter. I was present at an undersea, unexplained mass sponge migration.
Dr. Peter Venkman: Ray, the sponges migrated about a foot-and-a-half.
