[upon seeing the Slimer]
Dr. Peter Venkman: [very uncompfortably] Come in. Ray
Dr Ray Stantz: [on the walkie talkie] Venkman! I saw it! I saw it!
Dr. Peter Venkman: It's right here, Ray. It's looking at me.
Dr Ray Stantz: He's an ugly little spud isn't he?
Dr. Peter Venkman: I think he can hear you, Ray.
Dr Ray Stantz: Don't move! It won't hurt you.
Dr. Peter Venkman: [the Slimer charges at Venkman] Aaaaaahhh! Aaaaaahhh!
