HOTEL MANAGER: What was it? Will there be any more of them?
STANTZ: Sir, what you had there was what we refer to as a focused, non-terminal repeating phantasm or a Class Five Full Roaming Vapor….A real nasty one, too.
VENKMAN (Starts writing a bill): That’ll be $4,000 for the entrapment plus $1,000 for proton recharge and storage.
